  Marion County, Iowa -GIS and
Digital Mapping At Home

Whether we realize it or not many of us have become involved in using GIS and digital mapping in our everyday lives. Bing Maps, Google Maps, hand-held and in-car GPS units, E-911 Emergency Response, commercial and governmental web sites, smartphones and "dumb" phones, all involve GIS, GPS, and digital mapping in our lives. The purpose of this page is to provide access to software resources that include GIS mapping software, aerial imagery viewing software, and data resources you can use at home.

Marion County Government makes no implied or express warranty as to the safety, quality, or suitability of the software or web sites listed below. The user should always practice safe computing and practice do diligence before downloading and using any software obtained from the internet.

If you are primarily interested in viewing aerial imagery of Marion County and other Iowa counties, and you are using a Windows pc, the easiest way is to download and install the LizardTech GeoViewer and then go to the NRGIS Library and download the imagery to run in the GeoViewer. If you are an Apple Mac user, download and install the TNTatlas for Mac viewer, I have tested this and it works on OS X.
