The GIS Unit of Ascension Parish is proud to offer its services to help all departments of parish government as well as parish residents and the public at large. We have developed the most accurate base maps of the parish and we continually expand our database with data layers to produce dynamic maps in a variety of formats. We have developed a web based mapping system using ESRI GIS Technology. The maps can be accessed HERE with any web browser. These maps do not require you to download them or install any plugins. They can also be accessed on the iOS platform (iphone and ipad) as well as the Android platform using the "ESRI ArcGIS app" available in the app stores.

The APG GIS Unit is run by Kib Prestridge and Brian Martinez under the Direction of Brandon O'Deay, Technology Manager. We can be contacted directly by phone at (225) 450-1053 or by e-mail.
