What is zigGIS?
zigGIS is an ArcGIS Desktop extension that allows you to connect directly to spatial data stored in PostGIS. It is a lightweight option allowing you to centralize your spatial data into the leading open source spatially-enabled relational database.
Using zigGIS, you are able to take advantage of the advanced analysis and cartographic tools of ArcMap while leveraging the superior spatial data storage and management capabilities of PostGIS. zigGIS enables you to view, analyze and edit your PostGIS spatial data from within ArcMap.
The most exciting new feature of zigGIS is the introduction of multi-user editing of PostGIS data from within ArcMap. zigGIS now includes tools enabling you to check out your data and make edits with the native ArcMap tools.
Best of all, zigGIS enables all of this capability for users of ArcView on up without the need for additional middleware.
