Pierre Allain Obelix team

Post doctoral researcher at LETG-Costel and Irisa Rennes in the Obelix team. My work currently focuses on time series classification in satellite images for crop and grassland detection.

Time series classification

Using MODIS images at 250 m resolution, we aim at mapping crops and grassland in several test areas in France. Considering a set of satellite images over one or more years, a time serie is available for each pixel coordinates. The serie contains datas about the behavior of vegetation at this location. Thanks to machine learning algorithms and survey data, estimation of the type of crop is made possible in poorly known areas.
