MODIS Web Service
https://daac.ornl.gov/MODIS/MODIS-menu/modis_webservice.html
The MODIS Web Service is a tool that provides users with a means to order subsets of MODIS Land Products through standards based SOAP (Simple Object Access Protocol) established open source formats. Examples of currently supported open source formats: (1) OPeNDAP DAP, (2) OpenSearch and (3) Web Map Tile Service. The Open-source Project for a Network Data Access Protocol (OPeNDAP) Data Access Protocol (DAP) is a method for requesting and moving data on the web. Several of the DAACs including Physical Oceanography DAAC, GES DISC and LaRC offer the capability to use OPeNDAP to retrieve MODIS data products. OpenSearch is a protocol or format structure used to communicate search requests and search results. OpenSearch is used at LANCE-MODIS and LAADS Web. Web Map Tile Service (WMTS) is a protocol or format to host georferenced map tiles. WMTS is used with NASA EOSDIS Global Imagery Browse Services (GIBS) for serving MODIS data.
