Property Lines Map SD
A property lines map for South Dakota is the local parcel viewer. Open the county GIS map from Platbookmapper instead of relying on a statewide outline.

South Dakota has 66 counties. East-river farm counties and west-river ranch counties both map parcels locally. Section, township, and range still describe a lot of the land. The county GIS viewer draws it.
The line people want is the assessor's parcel polygon: the lot as the local office maps it for taxes. It shows which parcel is which. It does not mark iron pins, and it is not precise enough for a fence or a setback. Aerial photos underneath the line are clues, not monuments.
Open the South Dakota property lines map
- Start at the Platbookmapper home page and search the county, parish, or borough.
- Or open the South Dakota directory and pick the local viewer from the list.
- Follow the official GIS link. That leaves Platbookmapper and opens the local parcel map.
- Search the site address or the parcel number on the tax bill. Vacant land and new buildings often have no address in the file yet.
Platbookmapper only links out to those local parcel and lot-line GIS maps. It does not host the lots, and the line on the screen is not a survey.
Not a survey. County GIS and tax parcel maps are assessment and planning layers. They are not a substitute for a recorded plat, deed, or licensed survey.
