Presentation

An irrigation map over an important part of Catalonia region of Spain have been realized over the year 2018. This map have been obtained using the Sentinel-1 multi-temporal data (September 2017 and December 2018). The classification is based on the Convolutional Neural Network approach.

The classification of irrigated/non-irrigated parcels have been realized only over winter and summer agricultural plots.

The limits of the parcels used are defined using the SIGPAC (Geographical Information System for Agricultural Parcels) database .

The SIGPAC database provides us also with the land cover and the irrigation information over the parcels. The precision of the obtained map reaches 94% when compared to the terrain database of SIGPAC data.
