From May 13 to 17 the city of Milan hosted the world’s largest Earth Observation conference, the ESA Living Planet Symposium. Over 4000 participants (remote sensing experts, national and international companies, students, organizations and agencies from all over the world) were debating on state-of-the-art technologies and applications in the Earth Observation domain. And right in the middle of it: nearly 40 EAGLEs from all generations, excited to be part of this huge event.
But one by one and from the start: We arrived in Milan already two days before the conference using that free time to explore the city and visit the most popular places like the fortress and of course the famous cathedral.
Since it was the first conference for most of us, we had high expectations – and we were not disappointed. The scientific program and its hundreds of talks covered all the current driving topics with many specific application examples but also the introduction of new methods within the data analysis domain. In addition, lots of interesting posters were presented in the evenings, where also some EAGLEs contributed as you can read in the previous blogpost. Overall, socializing was a big part and it was very interesting to get in contact with the different speakers, presenters and companies during the breaks to discuss, ask questions and exchange knowledge. Some of us even got themselves some internships!
Besides getting the most information possible at the conference, we were of course enjoying the Italian way of life by eating tasty pizza and being daily customers of what is perhaps the best ice cream parlor you could imagine right around the corner of our hotel. After the Symposium, several EAGLEs took the chance and didn’t go back straight to Würzburg but to different destinations like Venice and other Italian cities, the Alps and Munich.
Overall, it was a very nice and inspiring week and it was very impressive to see what the Earth Observation community is capable of and we are proud to be a part of it. Also having all EAGLE generations together was very fun since some people don’t drop by in Würzburg very often due to their internships for example. We’re also looking forward to the next Living Planet Symposium in three years where hopefully many of us will present some awesome work.

An EAGLE student’s contribution to a study on mapping farming systems in Africa to be presented at ESA Living Planet Symposium 2019
In a few days, me and some other EAGLE program students are going to attend the “Living Planet Symposium 2019” by ESA which is amongst the biggest Earth observation conferences in the world. Part of my internship work at Remote Sensing Solutions GmbH is going to be presented as a poster in the poster session “A3.15 Land Surface Phenology” on Thursday, May 16 2019. Below you can find my poster entitled “New Ways To Utilize Sentinel-2 And Landsat Time-Series Data For Farm Systems Mapping In Africa” (click on it to display it in full size). So excited to be there 🙂

Since more and more EAGLEs of the 1st generation started to stretch their wings, it is time for one last recap. Over the last two and a half years, every one of us was quite busy learning new and exciting techniques and methods in the scientific field of remote sensing. We also were given the chance to expand our network and explore academic fields, which were not necessarily related to our previous occupations. As everybody has found a topic worth exploring, it is safe to say that the initially promised space for personal and academic development has been successfully established. This becomes even more evident, when the individual progress is observed more closely. People, who had difficulties following the classes at the start of the program, now develop their own processing frameworks and implement them in a variety of programming languages. Whereas those, who had prior experience in Earth observation, significantly expanded their knowledge and skill set. As one by one is leaving the eyrie (internally referenced as horst), we set out onto very different paths. Some of us are exploring the economic potential of remote sensing by starting their own company, while others reap the benefits of their networking efforts by joining one of the institutions connected to the program. Others again decided to stay close to the eyrie pursuing their PhD while simultaneously mentoring new generations of EAGLEs.
In sum, I think it is fair to say that we spent some great time together making new friends and finding interesting and exciting topics to discuss as we explored new aspects in the field of Earth observation and geoanalysis. Therefore, we would like to express our gratitude to all those who made this journey possible. May they keep out the good work, so that future generations can at least have as much fun as we had.

The internship at DLR gave me the opportunity to contribute to a case study investigating the effect of spatial resolution on the snow classification accuracy using different sensor images using Spot-5, Sentinel, Landsat, and MODIS for the time frame of 1984 to 2018. The study area covers the mountainous region of Europe with snow cover, for instance in Alps and mountainous parts of Spain, United Kingdom as well as Scandinavian countries. There are some general assumptions that the results of classifications from higher resolution satellite image will have higher accuracy, but there were no such scientific papers in the respective field that confirm this assumption. Therefore, the study aimed to fulfil this gap.
Talking about how this internship impacted my professional carrier, the divers working environment of DLR allowed me to interact with colleagues from different countries. As a result, I enhanced my skill sets by working in a multi cultural environment of DLR. Talking more about DLR, it is an accredited research institution especially in Geoscience related field, it strengthened my knowledge in the field of earth observation and gave me the opportunity to make professional connections in the related field.
The internship tasks were clearly structured and my supervisor was available most of the times for my queries. My working station was in the intern’s room, where all trainees from different departments work , so I had the chance to get introduced with other students.
The working hours are flexible, that gives you the freedom to manage your time in an efficient way and work in your own pace. You may work longer and save few hours for the Friday afternoon or come earlier in the morning and leave earlier.
During my internship I had the chance to participate in side events like workshops, seminars and a tour to the satellite Mission control centre which is offered for every new intern. Accommodation cost is higher in downtown of Munich as compared to the suburbs where the cost is relatively equal to Wuerzburg. The DLR office is located in the suburb of Munich called Wessling. It is an hour drive from the city centre to Wessling by “S-Bahn” , and it is easy to find a cheap accommodation near the respective area. Living in Munich gives you a opportunity to discover Museums and historical buildings for instance, “frauenkirche”, Nymphenburg Palace, Munich Residence, New & Old town Hall, St. Peter’s Church are famous, as well as there are many museums that are famous, which are : “Deutsches Museum Verkehrszentrum” It is a museum for vehicles, Old & New and Modern Pinacoteca. If you are a football fan, you can visit the famous football stadium, which is called “Allianz Arena”. Moreover, there is a famous festival in Munich every year called “October Fest” that starts from 21st of September and ends 6th of October with more than 6 million people in it. On the other hand, if you are a nature lover, Munich can offer you more, like you can reach the Alps in an hour by regional train for hiking, biking and camping. Not only that, here are many beautiful lakes in Wessling to spend your free time.
Last week, on December 7, the latest EAGLE generation also made its way to Oberpfaffenhofen near Munich to visit DLR’s Earth Observation Center (DLR-EOC). This year there were again very exciting talks on the following topics:
- Optical radar remote sensing for observing the coastal zone and river basins (Marco Ottinger)
- Earth observation for vegetation monitoring (Dr. Sarah Asam)
- Time series analysis of global snow cover (Dr. Andreas Dietz)
- Sensing the pulse of urban development (Dr. Felix Bachofer)
We also had the opportunity to talk to PhD students and researchers about their work, which was very interesting and informative.
As a highlight of our trip we got a guided tour through the German Space Operation Center (GSOC) – unfortunately Alexander Gerst just had a lunch break, so there was no time for a greeting from space. A visit to the Center for Satellite Based Crisis Information (ZKI) rounded off this exciting day.
All in all, the EAGLEs gained a lot of new experiences and deeper insights into the work with remote sensing data. Surely for some of us this will not be the last time at DLR, one or the other will do an internship there or write his/her master thesis.
But that’s not all! The next day we drove together to the Partnachklamm (gorge) near Garmisch-Partenkirchen in the Alps. For many it was a completely new experience to be so close to the Alps and to touch snow for the first time. After a more or less long hike, some “Kaiserschmarrn” at a Bavarian Alm and the crossing of the gorge, we went back to Würzburg in the evening.
For all of us, these were two nice days in and around Munich with new experiences in remote sensing as well as within the EAGLE community.

Today, the new EAGLE intake that pooled from all over the World has completed six academic weeks in the program – it’s about time to introduce ourselves!
Our diverse group of students spent their first week being drilled and thrilled by a series of introductory lectures by Dr. Claudia Künzer, Head of the Land Cover Department at DLR’s Earth Observation Centre. Along with teaching remote sensing, satellite systems and image analysis basics, she provided a personal insight into the sector in general and a multitude of applications. Then, ready for take-off, we started our regular courses ranging from theory and application of optical and radar remote sensing over relevant skills in programming, GIS and image analysis to vegetation biogeography, mineral exploration or scientific presentation. And as we settle into a naturally-busy schedule, jumping between lectures, we will try and keep you posted about what we are up to.
Finally, you are now able to sneak a peek at each of our individual backgrounds, motivation and what we intend to do for the next chapter of our lives. But for now…
The Third EAGLE Generation!
Written by Karsten Wiertz
This year, two of our EAGLE students had the opportunity to participate at the Copernicus Hackathon 2018 in Darmstadt. In the Hackathon, participants formed small groups, chose a task and had 24 hours to work on it with the technical support of mentors. The theme of this years’ hackathon was to solve one of three questions in the context of smart cities/urban planning with focus on traffic.
The teams could choose one of the following challenges:
- Help to prevent critical infrastructure like railway networks and highways from fire hotspots
- Monitor and help to improve air quality for bicycle speedways in Hesse
- Track changes in transport infrastructure (road and railway network) based on OpenSource data
Our two EAGLEs teamed up with two other participants and chose the challenge of tracking infrastructure changes. With their team, they came up with the name “RoadEO” (temporary name during the hackathon) and focused on the detection of changes related to newly built roads at different locations around the globe. As part of their task, they had to use open-source data and chose to start working primarily with Sentinel-2 data. In their business idea, they developed two main products, urban development and progress tracking. This provides investment-or insurance companies, local governments, construction companies, and many more with valuable information on the progress of infrastructure and the influence on the value of property. After just 24 hours of intensive work the teams had to present their results as demo-pitches in front of the other teams and got feedback and questions from the audience.
As part of the Hackathon, all participants had the chance to attend the INTERGEO 2018 in Frankfurt and pitch their business case live at the ESA booth on the trade fair. They were also invited to attend the “Open Day together with Bundesamt für Kartographie” with the topic of Open (geo-) data. Finally, on Wednesday, the 17.10.2018, all teams had to pitch in front of a jury and visitors of the trade fair. The jury evaluated the ideas based on different criteria and, after some time of waiting in excitement, presented their results. At last, we can proudly announce that the winning team of the Copernicus Hackathon 2018 is team RoadEO, which two of our EAGLE students, Karsten and Louis were part of.
Settling down in a foreign country can be a challenging process, especially if you do not speak their language well. Untangling the process can be daunting, complex, and usually lengthy.
Before you embark on this process, please make sure that you have enough money with you, so that you can survive until you have opened your bank account for your scholarship, blocked account or sponsors to deposit money for your use. Also, having someone who can help translate German is a boon to many of these steps. P/s: You also have the option to contact a student tutor for help.
Initial trip from the airport to Würzburg
The easiest option to travel to Würzburg is via train. You may purchase your tickets ahead of time via Deutsche Bahn website and search for a cheaper offer. Do provide ample time between your arrival and the train departure, as immigration clearance may take time if there’s a crowd and German trains are usually punctual.
Another option is by coach (locally known as bus). If you’re arriving at either Frankfurt or Munich International Airport, Flixbus provides cheap transport between the airport and Würzburg. However, coaches are definitely slower and less frequent than train.
German phone line (with data)
If you do not have any form of communication and want to avoid hefty overseas mobile charges, this is a very important milestone to clear. There are many options to choose – from phone shops with postpaid phone plans to the cheaper prepaid options from supermarkets.
In Germany, all SIM cards are sold locked. To unlock them for use, you have to complete a verification process, which require your passport, and a bit of time while they process your verification. If possible, complete the verification in the shop immediately after your SIM card purchase. This will save you the trouble of finding a WiFi source (especially if you do not have easy access to one) for the online verification. Do note that you’ll need a German address for this verification. It is possible to use an interim address (e.g. your temporary accommodation) for this.
For example, if you are purchasing the prepaid SIM cards from an ALDI supermarket, approach the cashier and ask for an in‑shop verification. While you might have to wait a while before the cashier is free to help you with the verification, it’s useful in the long run to get your communication channel up and running as soon as possible. Beware though, as some of us were unlucky and encountered service staffs that only spoke German.
Transport within Würzburg can be pricy. A bus ride will cost at least €2.70 per trip. Until you get your matriculation card (which also functions as a transport pass), it is recommended to get the day pass to cover your transport needs. The day pass can be easily obtained from any bus conductor or ticketing stations and costs €5.10.
In the unfortunate event which your matriculation card will take more than two weeks to issue, it will be more economical to purchase a monthly ticket that costs €45. This ticket allows you to travel within Würzburg and its surrounding areas without limitations for a month.
OpenStreetMap is the recommended map service for Würzburg, as Google Maps does not have information about the tram (locally known as street train, or Straßebahn) and bus services that ply in Würzburg. You may use also apps such as Bayern Fahrplan to help you with moving around Würzburg (Android and IOS).
Health insurance is required in Germany. You have a range of choices from both public and private health insurance companies. Do note that choosing between public or private health insurers will have short‑term and long‑term consequences, especially if you have plans to remain in Germany after your studies. You will not able to return to public insurance once you switch out to a private insurer. There is also an age‑restriction for entry into public health insurance (e.g. below 30 years of age). It is essential to do your due diligence before choosing.
If you choose a private health insurer, you would need to get an exemption letter from a public health insurer. One option is to visit the AOK Bayern Student Service Office in Sanderring. As long as your private health plan provides sufficient coverage and is valid for your whole school term (ie. at least 2 years coverage for the EAGLE programme), you may obtain the required exemption letter.
Bring along all necessary documents as instructed by the matriculation letter to the international office. Once you have matriculated, you will need to activate your online student account. The login information will be sent via email. As the activation is not immediate and will take a few days, do complete this online activation as soon as possible.
You will also need to wait for your matriculation card to be produced. The International Office will contact you once the card is ready. Take the card to a validation machine (available in the library and ground floor of building 82). Follow the instructions provided by the Office and your card is now valid for “free” transport.
This is a crucial milestone. Basically, a German address is required for matriculation, phone verification, health insurance, unlocking a blocked account (if you have one), and even opening a bank account. Not to mention, there will be less stress in your life with a secured roof over your head.
Unfortunately, the process of obtaining an accommodation is stuck in a loop with the bank account and residence permit. Simply put, a proof of residence (usually residence permit) is required to open a bank account, which may be required to pay for your accommodation, which then is required to apply for a residence permit.
Fortunately, alternatives are available to break this loop. Not all accommodations require a German bank account for payment. Bring sufficient cash to Germany so that you can use them to pay for an accommodation if needed. You may also wire or transfer money from an overseas account directly to your landlord to pay for your accommodation’s initial payment, if this option is available.
If you are fortunate enough to secure an accommodation before you arrive at Würzburg, give yourself a pat on the back. Demand for accommodation here is way more than supply – even the student apartments may have a waiting list of one semester or more! There is no easy way around finding an affordable accommodation here. You will need to use all possible avenues, such as Studentenwerk, WG-Gesucht and even word‑of‑mouth, until you find a suitable place. In the interim, you may try Babelfish or Jugendherberge for a cheap temporary accommodation.
While opening a bank account can be annoying as part of the bank‑accommodation‑permit loop, there are possible bypasses (e.g. obtaining an official letter with your name and German address on it or opening an account with an online bank).
To open an account in the usual brick‑and‑mortar banks, you will require a residence permit or an official letter with your name and German address on it. As the contract for opening a bank account is only legally binding in German, you will need to either understand German or bring someone who can translate German to you. A fee is required in order to keep the current account operational. Some banks offer a student account which has zero fees, but these accounts are usually age‑restricted (e.g. below 27 years of age).
If you would prefer to avoid the traditional banks, online banks are available for your use, such as N26. As with all financial decisions, do take time to research and consider your options carefully.
In order to obtain a residence permit, you need an accommodation, period/full stop. When you secure one, you will be provided with a letter for registration at the town hall (local term: Rathaus). You will also need your passport, matriculation letter/matriculation card, and bank account statement. If you are married, a translated copy of your marriage certificate (in English or German) is required too.
After you have obtained a residence permit, you may receive a letter from the German broadcasting institution (Beitragsservice von ARD, ZDF und Deutschlandradio). The legal ruling is that each residence is required to pay the fee, regardless of whether you use their services. If you live alone, do register with them as instructed and pay the fees (€17.50 per month). If you have housemates, check if anyone is already paying, get their account number and inform the Beitragsservice that you’re covered under that account number.
Electronic residence card
The final milestone. You are only allowed to book an appointment with the Rathaus when you have less than three months remaining for your student visa. Depending on the length of your entry visa (e.g. some were given three months while others have six months), you might have to wait.
On your first visit, you will not be processing anything. Instead, you will be given a form to fill and a second appointment on another day. This means, please do not come to the Rathaus with less than a month of your visa remaining.
On your second visit, you will need to bring all the documents as instructed in the form and €107 (either in cash or by debit card). You will need to come half an hour before your given appointment time to provide your mugshots and biometrics (fingerprints, etc). That costs €7. Your application will then cost another €100. It’s then time to return home and wait for two letters (about a few weeks later).
When you get the two letters, bring them for your third visit to the Rathaus and get your card. Congratulations, you are now a third state citizen in Germany! Do check the validity date on your card. If you only have one year before it expires, then you will need to repeat the whole application process (including another set of mugshots and biometrics) in your second year here.
Other useful information
If you come from a country/place which businesses and shops open till late and on weekends, be prepared for a major change. Not only do shops and supermarkets in Bavaria close at 8pm or earlier, they are also non‑operational on Sundays and public holidays. While there are exceptions such as certain F&B outlets, this means that you will need to stock up with food (and party beers) beforehand to avoid nuisance during these periods.
Remember to bring your own bags for shopping. Shops in Germany do not provide free bags for your groceries and other shopping goods. You will need to purchase these bags at a small cost from the cashier if you require them.
You may refer to the University calendar here. That should help with your scheduling and time management.
Tips for convenience
Bring more money if possible. Until you get access to your funds (e.g. unblocking of blocked account), your funds will be mostly restricted to what you bring. For blocked account holders, you will need to undergo a verification process before your account can be unblocked. Verification may be delayed for many reasons. Do take that into consideration when planning your money.
Most entry visa do not come with an innate work permit for students, which is a pre‑requisite for a student job. If you wish to get a work permit, please visit the Rathaus.
Having someone to translate German for you will be highly helpful. In fact, it may even expedite the process considerably. While you can approach the student tutors available at the International Office, don’t shy away from asking your fellow coursemates and/or seniors who can speak German. This will double as an icebreaker, which will make a great start for your student life in EAGLE!
Settling down in Würzburg may seem complex and frustrating when you’re unprepared for how Germany conducts her administrative matters. For the well‑prepared, this can be a smooth process. If you are ever frustrated or depressed about this matter, remember that you can always approach your seniors – we’ve been through the process! Feel free to contact us through our contact form. We look forward to meeting you in Würzburg!

Yesterday, many Geography students and some lecturers of the University of Wuerzburg met at the center lawn of Campus Hubland for the annual Geography summer party, organized by the faculty’s Student Council. One highlight, as every year, was the football tournament, in which nine teams, all drafted explicitly for the event, competed against each other to win the “Mohorovičić Cup”. The cup is named in honor to the Croatian meteorologist and seismologist Andrija Mohorovičić, who is considered as the founder of modern seismology and after whom the “Mohorovičić discontinuity”, the boundary between the Earth’s crust and the mantle, is named.
With “Team EAGLE”, the University’s EAGLE Master students also participated in the games, playing the important role of representing the Geography Institute’s remote sensing community at the cup. Following the model of Europe’s most successful football clubs, Team EAGLE was formed out of an international selection of players, being (by far) the team with the highest international diversity in the whole tournament: Team EAGLE represented five nationalities, including German (three players), Pakistani, Iranian, Afghan and Singaporean (each one player). Moreover, team EAGLE was one of the two only teams to be multi-gender, being supported on the field by a female striker, who always was dangerous in front of the opponent’s goal. A cheering crowd of EAGLE students, sitting directly next to the field, celebrated the team’s efforts to score enough goals to make it through the group stage, consisting of four games from which four teams remained to play in the semi-finals and final game.
While the individual class of each EAGLE player was clearly outstanding against many “hobby” players of the other teams, a little lack of practice playing in the chosen formation caused the team to be not as effective as needed, especially in front of the opponent’s goal. This, combined with some unlucky situations where the goal post was involved in saving the opponent from being played off by team EAGLE, forced the latter and its supporters to accept that they had been kicked out of the tournament after four hard fight games.
However, being aware of how loosing can make you even stronger, team EAGLE is prepared to fight back one year ahead and to bring the cup home to the Oswal-Külpe-Weg. With a lot of young and fresh talents, expected to arrive in October this year, team EAGLE will improve its skills, its tactics, its class and – its unprecedented, shining spirit!
We will be holding our annual EAGLE Summer Dialogue and Barbeque on 22 June 2018. Here is a quick peek at our programme:

The EAGLE Team
students have been studying within the EAGLE programme in total
students have already graduated the EAGLE programme in total
Last month, from 19-21 February 2019, a group of EAGLE students participated at the “Big Data from Space” conference in Munich. The conference co-organized by ESA & DLR focused on three main topics:
1) Latest advances in machine and deep learning
2) Latest developments of user-friendly platforms to process Big Data
3) New methods to gain knowledge from Big Data in Earth Observation
The aim of the conference is to bring European researchers, companies and institutions in the field of Geospatial Big Data together to strengthen the exchange of methods, technologies and user needs between stakeholders. Therefore, new methods and applications for innovative data analysis were presented on the conference. Additionally, the combination of different spatial data sources and geospatial cloud computing platforms were promoted. Listening to all these presentations from scientists and developers gave a great insight about the current state of research in Big Data Processing and Artificial Intelligence Development. During the coffee breaks were many opportunities to interact with presenters and participants to not only strengthen our knowledge and but also to gain contacts for possible internships. Various other topics were also presented during the poster session. There we had chances to ask questions and discuss with authors as well.
In conclusion, we gained a better knowledge about the current state of research on geospatial big data and its applications and also had the great opportunity to meet up with other participants and discuss with them.
Over the last years, webcams and real-time monitoring has become more and more popular. Especially in mountainous regions webcams are widespread (e.g. ski fields, lakes, traffic, …). As these images provide information in high spatial and high temporal resolution, the question the scientific community is rising and trying to answer is, whether this data could be usable for spatial analysis purposes. The major challenge in this case is to properly georeference webcam images to a map coordinate reference system. Even though from a geometric point of view this can be solved, many parameters are very difficult to be measured in an accurate way (e.g. orientation of the camera system). Therefore, beside the geometric parameters the standard approaches use ground control points (GCPs) that are accurately measured in the field to align the image.
During my innovation lab at the European Academy (EURAC) in Bolzano, I developed the proposed python package georef_webcam providing a tool to georeference webcam images very accurately without knowing all the projection parameters very accurately. It is also compensating the need to go into the field personally, as you can derive GCPs from remarkable man-made structures or from morphological features (edges) in the panoramic view of the image and the Digital Elevation Model (DEM). As cameras are no ideal systems, they usually induce distortions into the image, which must be compensated for accurate georeferencing. The proposed tool is implementing a new approach of polynomial fitting to compensate these errors. The whole georeferencing procedure is wrapped up in a command-line based python script, which is making this procedure as user-friendly as possible. There is no need to deal with the projection procedure itself. The user is just asked for the needed parameters and to draw the GCPs and the Fitting points in a predefined QGIS project. All substeps can be executed iteratively to produce a result that meets the user requirements.
As this script is in early development stage, I cannot guarantee for its full functionality. However, If you want you can also visit to my Github for more information.

Methodology to delineate the critical regions for mitigation of carbon emissions due to groundwater pumping
Figure: Map of the study area and canal network of central Punjab with critical regions
After estimating the total carbon emissions from groundwater pumping (see the previous blog), I wanted to delineate the critical regions of the study region with high carbon emission rate. Therefore, this present study addressed the expansion of groundwater use that not only resulted in a speedy decline in the groundwater table but also added to the problem of carbon emissions (C-emissions) in Punjab. Estimates of C-emissions from groundwater pumping for irrigation in central Punjab indicated that during the last 15 years (1998 – 2013), the groundwater levels had fallen by 8.89 m; pump set density (per 1000 ha) increased by 45%; groundwater use increased by 140 Mm 3 ; energy requirements increased by 4845.1 MkWh (90%), all this resulted into an increase in C-emissions by 984.1 kilotons (30%). The relationship between carbon emissions and groundwater depth showed that for each meter fall of groundwater level in central Punjab, C emissions will increase by 2.67 g/m³. The present level of groundwater exploitation in Bhawanigarh, Dharmkot, Dhuri, Malerkotla I, Malerkotla II, Nabha, Nakodar, Sangrur, Samana, Sherpur, and Sunam is considered as a threat to the environment and should be targeted to reduce C-emissions.
For your views and consideration, visit Groundwater for Sustainable Development (ELSEVIER).
Recently, I published a case report, which was based on a methodology to estimate carbon emissions from groundwater pumping in Punjab, India. The report was correlated with the fact of the green revolution momentum in the late 1960s and 1970s that resulted very negatively to some of the Indian states, especially Punjab. Due to this, the carbon emission patterns due to groundwater pumping in the state have changed enormously, and today the sector is one of the main contributors of C-emissions. Therefore, this study identified the critical blocks of central Punjab that should be aimed at reducing the carbon emissions of the groundwater economy. This study was thus based on the regional scale and highlights various factors that played a crucial role in contributing to these emissions. For the year 2013, the energy requirement for groundwater pumping computed as 7919.6 MkWh and the contribution to the overall C-emissions was 1349.6 (’000) ton. Along with that, an overlay analysis of the choropleth maps (tubewell density, groundwater draft, groundwater depth, and C-emissions) showed that SC-III zone was the most critical zone of central Punjab.
For your views and consideration, visit to Carbon Management (Taylor and Francis group).
The OpenLayer Plugin for QGIS provided all my basemap layers for quite some time now. But since the eagerly awaited launch of QGIS 3.0 earlier this year this plugin became incompatible, leaving you with two options:
- you either gather and compile all XYZ Tiles manually,
- OR run a Python Script.
Open the Python Console (Ctrl+Alt+P), take the script and hit “run command”. Done!

Once I completed coding this, I realized that installing the packages might only be half the job. You’ll most likely want to load them into your R session before executing the rest of your code.
While researching how to operate vectors on library() I found a neat existing solution.
But adding this inside the loop will do the trick.

The new 2017 EAGLE students have been welcomed to Wuerzburg and recently started their studies. Our webpage will be updated as soon as reports and photos about the new students are available.
Since the first ever semester of the EAGLE program has come to an end, we think it is time to come together and enjoy a nice summer evening. On the 23d of June, the EAGLE students invite to a great BBQ at the University of Würzburg. We hope for a good mixture of students, lecturers and other EAGLE interested people. The party will be a great place to share the experiences and information with each other. If you are interested to join, please fill in the contact sheet. More information will be provided via email – stay tuned!
