Iowa GIS Maps by County: The Parcel Viewer Each Uses
Which parcel map software each Iowa county uses (99 of 99 verified), how to search the common viewers, and a link to every official map.
Looking for Iowa county GIS websites? Iowa has 99 counties, and their official parcel maps do not all run on the same software. Knowing which viewer a county uses tells you what the search box expects and where the parcel report is.
If you look up land in more than one Iowa county, you will notice the parcel maps don't match. That is because each office chooses its own software. Below, all 99 Iowa entries in our directory are listed with the viewer each one uses, plus tips for the most common types.

Before you rely on what you find
Treat these maps as a starting point. Parcel outlines are tax-map drawings and can be off from the true line; the recorded deed and a licensed survey are what count. To check flood zones, soils or wetlands for a spot you found, open it on the Platbookmapper Land Map, which pulls FEMA, USDA and U.S. Fish & Wildlife layers.
