  "description": "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.",
