GIBS Tiled Web Mapping Service (TWMS)

The TWMS specification is a custom extension to the OGS WMS standard developed by the NASA Jet Propulsion Laboratory. Similar to the OGC WMTS specification, TWMS introduces a 'tiled' approach to imagery requests so that tiles may be pre-generated and cached for fast response. Unlike WMTS, the TWMS standard retains the usage of requests containing geographic coordinates for imagery. However, it only responds to a limited number of predefined geographic regions, creating a gridded access pattern.
