Putnam County uses several software packages to maintain our data. We use ESRI software products including ArcMap, ARC/INFO, ArcView and ArcExplorer. We also use AutoDesk's AutoCAD software products including Land Desktop, Civil Design and Map.
You will need software capable of importing and using GIS data. There are many free data viewing software packages available on the internet. ESRI's ArcExplorer, a basic GIS data viewer, can read the shapefile format and is available as a free download (click on the link).
