Geographic Information Systems

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 that you can use to access some of our data dynamically @

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. The maps on this page will help you know more about your particular area and neighborhood. As with the Links Page, these maps may be useful to students with school or other projects.
