We congratulate Maninder who successfully defended his M.Sc. thesis “Comparing the performance of crop growth models using synthetic remote sensing data at DEMMIN, Germany” supervised by Martin Wegmann and Christopher Conrad.
Maninder Singh Dhillon handed in his M.Sc. “Comparing the performance of crop growth models using synthetic remote sensing data at DEMMIN, Germany” supervised by Thorsten Dahms with the first and second supervisors Martin Wegmann and Christopher Conrad, respectively.
His M.Sc. defense will be on Monday 18th at 2pm in room 0.004 (Oswald-Kuelpe Weg). Read the abstract of his M.Sc. for more details about his research project.
Abstract: Climate change, natural resource degradation, and population growth are increasingly challenging food security. Climatic effects such as warming temperatures, and decrements in soil moisture have already stagnated the winter wheat yields in many parts of the world. The present study was conducted over three years from 2015 to 2017 on a main agricultural production region of North-East Germany. Five widely used crop models, namely, WOFOST. CERES, Aqua crop. LUE and CropSyst, are compared to predict the biomass of winter wheat crop. The study stresses the use of remote sensing with crop growth models, as they lack spatial information on the actual conditions of each field or region. It also elaborates the concept of data fusion, in which both Landsat (30 m) and Modis (500 m) are combined to get synthetic remote sensing data of 30-meter spatial and one-day temporal resolution, in crop growth modeling with its contribution to crop growth models. Measurements of the biophysical parameters such as Leaf Area Index (LAI), Canopy Cover (CC), Fraction of Photosynthetically Absorbed Radiation (FPAR) were grouped according to the phenology using the BBCH characterization (Biologische Bundesanstalt, Bundessortenamt und Chemische Industrie). The analysis was carried out for winter wheat during the years 2015 to 2017 and included a detailed comparison of the simulated and measured crop biomass as well as an impact of climate parameters such as temperature stress, soil moisture stress and vapor pressure deficit (VPD) on crop growth, and an evaluation of the modelled crop biomass. The study shows that the models (Aqua crop, CropSyst, and LUE) that require fewer input parameters to simulate crop biomass are well suitable and easier to implement.
Our new EAGLEs arrived!
We welcomed our new international EAGLE students from the US, Ecuador, Bangladesh, Ruanda or Germany for the upcoming winter term and introduced the lectures as well as the courses. In the evening we had a joint dinner to get to know each other. The first course started on Tuesday morning at 9 am on fundamentals of Earth Observation by Claudia Kuenzer.
On Monday, 24th of September from 1:30 onwards the following EAGLE students will present their M.Sc. idea. Everybody is welcome to join their presentations and to provide feedback:
“Time-Series Analysis of Sentinel-1 and Sentinel-2 Imagery for Detection of active Morphodynamics in the Atacama Desert, Chile”
“Risk assessment for flood events based on remote sensing data – a case study for North-Rhine Westfalia, Germany”
“Remote sensing of water quality using Sentinel-2 towards a potential separation of harmful algal blooms from other Algae”
“Assessing the development of circular irrigation in South Africa since 19*”
“Tracking crop penology based on S1-Time series”
“Solar power potential in Portugal”
“An approach to optimize object-based classification: Mapping dead trees and gaps in Białowieża Forest”
“Deep learning for Instance Segmentation and a comparison to a Conventional Segmentation on historical aerial images of the Second World War”
“Drought Monitoring in University Forest with Hyper-Spectral And In-Situ Data”
Our 2018 EAGLE summer dialogue took place last Friday, 22nd of June and was a great place to meet all students, lectures, staff of the department and quite some external guests from all around Europe. Thanks to our EAGLE organizers and all the external guests coming to Würzburg to enjoy an evening of BBQ. We are also grateful to our guest who spend time with our students discussing future opportunities of internships, MSc thesis or job applications. Quite some business cars were exchanged.
We are very much looking forward to the 2019 EAGLE summer dialogue with probably even more students and guests!
This year, Dr. Rene Colditz from the European Commission joined the EAGLE summer dialogue as keynote to outline his career path from being a student in Würzburg to being a policy offer. Rene studied Geography in Würzburg, continued with his PhD on MODIS land cover classification under the supervision of Stefan Dech before working for CONABIO, Mexico, for nearly 10 years as a remote sensing specialist. Now he works as policy officer at the European Commission, DG CLIMA, C3 Land use and Finance for Innovation in Brussels, Belgium.
the application deadline for our next term of the international M.Sc. program EAGLE “applied Earth Observation and Geoanalysis of the Living Environment” is approaching. Application for the upcoming winter term are accepted until May 15th. More details on the application process at http://www.eagle-science.org/apply
