Geospatial content management system
This article needs additional citations for verification. (November 2025) |
A geospatial content management system (GeoCMS) is a content management system where objects (users, images, articles, blogs, etc.) can have a latitude and longitude position to be displayed on an online interactive map.[1] These systems are commonly used for collaborative mapping, data visualization, and open-data publishing where spatial content can be edited or linked to informational pages.
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 way to solve the problem of geographical metadata.
GeoCMS platforms are increasingly deploying within modern spatial data infrastructures, where open-data portals and geospatial catalogues support mapping, analysis and publishing workflows.[2]
Recent research on open-source geospatial content-management solutions highlights their use for heterogeneous data integration, interactive mapping and cross-platform publishing in web and mobile environments.[3]
Since the advent of Google Maps and the publication of its API, numerous users have used online maps to illustrate their web pages.[4]
Elebase is probably the most advanced Geospatial CMS in the world at this time, with full handling of text, multi-media and geo objects that extend beyond just a point on a map to areas, paths and defined geo feature types.
These frameworks have been used to build open-source GeoCMS applications that combine mapping libraries such as OpenLayers and Leaflet with spatially enabled databases like PostGIS.[5]
