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.", "distribution": [{"@type": "dcat:Distribution", "downloadURL": "http://map1.vis.earthdata.nasa.gov/twms-geo/twms.cgi?request=GetTileService", "format": "ZIP", "mediaType": "application/zip"}], "identifier": "NASA-424", "issued": "2018-06-25", "keyword": ["digital", "geography", "imagery", "maps", "tiles", "twms"], "landingPage": "https://wiki.earthdata.nasa.gov/display/GIBS/GIBS+API+for+Developers#GIBSAPIforDevelopers-TiledWebMapService%28TWMS%29", "modified": "2025-04-01", "programCode": ["026:005"], "publisher": {"@type": "org:Organization", "name": "National Aeronautics and Space Administration"}, "rights": null, "theme": ["Earth Science"], "title": "GIBS Tiled Web Mapping Service (TWMS)"}
