Geospatial content management system

From Wikipedia, the free encyclopedia

A geospatial content management system (GeoCMS) is a content management system where objects (users, images, articles, blogs..) can have a latitude, longitude position to be displayed on an online interactive map. In addition the online maps link to informational pages (wiki pages essentially) on the data represented. Some GeoCMS do also allow users to edit spatial data (points, lines, polygons on maps) as part of content objects. Spatial data can be published by GeoCMS as part of their contents or using standardized interfaces such as WMS or WFS.

A GeoCMS can have a map of registered users allowing to build communities geographically, by looking at users location. The help of wiki for describing geographical layers present a simple way to solve the problem of geographical metadata.

Since the advent of Google Maps and the publication of its API, numerous users have used online maps to illustrate their web pages. Google Maps is in itself not a GeoCMS but is a powerful building block.

Similarly Mapserver is also a powerful building block for creating GeoCMS.

Tiki Wiki CMS Groupware was the first CMS to become a GeoCMS in early 2003, it is now becoming popular on various other CMS especially since the publication of the Mapserver API in 2002 to many scripting languages: PHP, Python, Perl, Java,...
