Tutorials for using NASA PO.DAAC data with Geographic Information Systems (GIS)

NASA Earthdata GIS (EGIS)

Select NASA Earthdata PO.DAAC collections are available through the NASA Earthdata GIS (EGIS), a resource for distributing cloud-native, GIS-ready NASA Earth Science data, services, and resources. These include ArcGIS and Open Geospatial Consortium (OGC)-compliant raster and feature geospatial services. To access the full NASA Earth observation repository for data download, please visit Earthdata Search. Core functionality is available for EGIS web services; however, some unique behaviors persist. Please see our Expected Behavior and Known Limitations for more details.
