PrimaGIS is a collaborative Web mapping application for Plone that is built on top of MapServer, Python Cartographic Library (PCL), and Cartographic Objects for Zope (ZCO). In addition to supporting traditional spatial data sources (e.g. shapefiles, PostGIS databases, raster images, and WMS/WFS services), it allows users to combine data from a content management system (Plone) within the maps.
