Louisiana Parish GIS Websites: Parcel Viewers by Parish
Which parcel map software each Louisiana parish uses (39 of 64 verified), how to search the common viewers, and a link to every official map.
Looking for Louisiana parish GIS maps? Louisiana has 64 parishes, its version of counties, and their official parcel maps do not all run on the same software. Knowing which viewer a parish uses tells you what the search box expects and where the parcel details are.
Louisiana does not run one statewide parcel map that every parish uses. Each local government picks its own viewer, so the screen you see in one parish can look nothing like the one next door. This guide sorts all 64 Louisiana entries in the Platbookmapper directory with the software behind each official map.

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.
