WebGIS service standards are the basis of modern WebGIS technology.
In order to realize the interoperability of spatial data and promote the sharing of spatial data among heterogeneous platforms, OGC (Open Geospatial Consortium, Open Geospatial Consortium) has been committed to providing standardization of software, data and services in the geographic information industry, and has formulated a series of spatial The service specification of the data, such as WMS, WMTS, WFS, etc. Based on the OGC standard specification, the global sharing and interoperability of geographic information has become an inevitable trend in the development of GIS technology. Therefore, at present, most of the open map service resources are released based on the OGC service specification, providing standard OGC map services to the public.
