| 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 Agro-informatics Platform (FAO AP) at this address: https://data.apps.fao.org/?lang=en&share=f-3af5703a-3b9f-4976-9d57-5391038c8674 or through ASIS ArcGIS Online at https://data.apps.fao.org/. ASIS datasets have been published by FAO as Image Services (WMTS) 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.
From 20 January 2026, some adjustments have been introduced to ASIS assets on GEE. Read details here:
