OGC Service
OGC (Open GIS Consortium) is a voluntary, non-government and non-profit organization, devoted in developing an open system to run geoprocessing and leading the interoperability standard of geographic information.
WMS, WFS, WCS and WMTS data are provided in “OGC Service” of SuperGIS Desktop. WMS (Web Mapping Service) is the standard protocol defined by OGC for internet client end to demand the mapping. Through WMS client end can require the specified layer and some parameters like size or reference coordinate system provided for mapping. Besides, WFS (Web Feature Service) is the standard protocol defined by OGC, the features are supported to Insert, Update, Delete, Query and Discover. Client end sends the request of the features needed by the application through WFS to obtain the data. WCS (Web Coverage Service) is the standard protocol defined by OGC for client end to obtain the image data of specified spatial area and band, such as satellite image and remote sensing image, etc. WMTS is based on Map Tile technology that the server will pre-generate the map tile imagery (or cache the map imagery in advance), as the front-end requires the map imagery of a specific region, the server will transmit the map tile of that region to display on the front-end.
