A web platform was developed for an automatic district-scale satellite data acquisition process and to be made available for interested parties in open access, as it does not require any knowledge of remote sensing data acquisition and processing. The web platform requires the user to select the area of interest and type of the boundary for satellite data extraction. The advantage of this platform is the ability to extract the satellite data for only cropland areas by excluding other land use/cover types in the district.

Note: If the selected district does not have cropland areas, you will receive an error "Error generating chart: No properties to chart" instead of graph.

 (Video tutorial will be available soon)

The croplands masked using land cover and use product MODIS-MCD12Q1 V6, which provides yearly information on global land cover types since 2001 (Friedl and Sulla-Menashe, 2019). In our study, we used the sub-model “Annual International Geosphere-Biosphere Programme (IGBP) classification”. As cropland, we merged the layers 12 and 14 in order to capture all possible croplands in the selected areas. All years since 2001 until 2020 were combined in order to produce a single mask for croplands.
