Nationwide parcel GIS directory: official county maps across the USA
Platbookmapper is a nationwide directory of direct official parcel maps. Zoom a county on our USA map, open the local GIS, and land on the same interactive viewers counties publish for towns, vacant lots, and industrial parcels — without hunting hubs or dead search pages.
Platbookmapper is an Amazon Associate. If you buy through an Amazon link on this page, we earn a commission. The link is a product, not the county map.
Towns and places on this map
What the directory is for:
- Every county outline — Census boundaries so you can find the right local government.
- Official outbound GIS links — ArcGIS Experience/Web AppViewer, Beacon Map, county iMaps, and similar interactive parcel tools.
- City viewers when needed — Independent cities and major city tools (for example Detroit) when that is the right map.
- Growing coverage — We keep adding verified direct map URLs state by state.
Who usually opens this map
People land here when they need a local parcel map for a town they are buying in, vacant land they are evaluating, or industrial site due diligence — and they want the official viewer, not a sketch.
Vacant parcels and buildable ground
Vacant parcel questions are local: each county map shows empty polygons differently. Use our directory to reach the official tool, then read land-use codes and call planning before you assume buildable.
Local industry and land use
From farm counties to port cities, the directory’s job is the same — get you to the official interactive map that local industry, assessors, and buyers already use.

- If a county still lacks a link, tell us and we will prioritize it.
Not a survey. Screen maps are for reference. Legal boundaries, fencing, and title work need recorded plats, deeds, and a licensed surveyor.
