From http://www.directionsmag.com/articles/fun-with-georss/123114Summary:
If you know what RSS is, georss is a logical step forward. but, since should people only vaguely know of RSS, let's start there. RSS stands for Really Simple Syndication or Resource Description Framework (RDF) site summary or rich site summary. this article, by Adena schutzberg, explains RSS and georss, tells us why it's important, and provides examples of ways you can "play" with georss.

Mssqlspatial
Mssqlspatial complies with OGC Simple Features Specification for SQL Revision 1.1 and is built based on nettopologysuite and sharpmap. It is divided into three modules, namely, ETS, sharpmap, and sqlclr. sqlclr is divided into CLR integrated implementation code. It mainly implements space database encapsulation
Nettopologysuite is the C #/. Net version of the famous JTs topology suite. JTs topologysuite is an OpenGIS standard GIS analysis and operation class library.

OpenGIS (Open geodata interoperation specification, ogis-open geographic data interoperability specification) was proposed by the American OGC (OpenGIS Association, OpenGIS Consortium. As a non-profit organization, OGC aims to promote the adoption of new technologies and business methods to improve the interoperability of geographic information processing ), it is committed to eliminating geographic informa
RecentlyCodeTo call the OGC service, so I checked it online. There are mainly the following solutions:
1. Use gsoap, cross-platform, and gsoap is an open-source project, which allows you to conveniently use C/C ++ for soap
Programming on the client and server without having to understand the XML and soap protocols
2. mssoap3.0, Microsoft products
3. an ATL library of ATL server, which is currently open-source
