Data Access, Image Services and Metadata
Maps/graphs/tabular data presented on this website are pre-processed, published-ready products, originated from the satellite imagery (raster format). All ASIS raster datasets (global extent, 1 km resolution, 1984-present, over 16, 000 layers) can be interactively visualized/analyzed at FAO Hand-in-Hand Geospatial Portal (HiH GP) at this address: or through ASIS ArcGIS Online at

ASIS datasets have been published by FAO as Image Services (WMS) that allow for further analysis in an array of third-party applications. The datasets also have been disseminated on Google Earth Engine (GEE). To request the access to ASIS asset on GEE, please send an email to [email protected], providing your GEE account.
