NASA's Global Imagery Browse Services (GIBS) are designed to deliver global, full-resolution satellite imagery to users in a highly responsive manner, enabling interactive exploration of Earth. GIBS provides access through five mechanisms:
- An Open Geospatial Consortium (OGC) Web Map Tile Service (WMTS) that supports key-value-pair and Representational State Transfer (REST)ful tiled requests
- An OGC Web Map Service (WMS) that supports a key-value-pair non-tiled requests
- A Tiled Web Map Service (TWMS), an unofficial extension to the OGC WMS, that supports key-value-pair tiled requests that match the exact geographic tile boundaries
- Script-level access through the Geospatial Data Abstraction Library (GDAL)
Access to GIBS via the protocols above is explained in the link below. In addition, source code for the GIBS tiled imagery server and tiled imagery storage format is also available.
