PrimaGIS Mapping Solution Spatial Extension
Sponsors
<-- Free GIS Software & Resources
PrimaGIS is a mapping solution meant primarily as a spatial extension for Archetypes based objects. The idea is to allow existing Archetypes based objects to be presented on predefined maps and allow users to easily access this spatial information in relation to the primary information of the objects. It is possible to have non-AT objects as data items also. PrimaGIS is not a standalone application, but builds on top of Mapserver, Python Cartographic Library (PCL) and Cartographic Objects for Zope (ZCO).

Setting up a PrimaGIS instance, including acquiring the initial spatial data and setting up the underlying ZCO hierarchy, requires some domain specific knowledge about Mapserver/ZCO, but afterwards using and updating the map and spatial data is done 100% through-the-web using the Plone interface and should require no special skills in addition to knowing normal Plone content administration.
Spatial extensions to new and existing Archetypes objects are added either explicitly by implementing an interface (IGeoAware) or implicitly by using geo-aware proxy objects, in the latter case no changes are needed to existing objects and products. Each proxy object represent a location on a map and may refer to arbitrary number of Archetypes objects. In addition, an Archetype object may have spatial references to arbitrary number of maps and locations, when using the proxy approach.
