Property lines & parcel boundaries
Fence fights, shed placements, and vacant-lot walkthroughs all start with the same question: where are the property lines? County GIS shows parcel boundaries for tax purposes. Here is how to find property lines, read a property boundary map, and tell lot lines on a lot map or acreage map from a true survey.

Property lines on a screen
On a county viewer, property lines are the edges of tax polygons. They help you orient a vacant parcel against the road, rail spur, or neighboring plant. They do not certify where a licensed surveyor would set iron pins.
Parcel boundaries
Parcel boundaries come from the cadastral fabric — compiled from plats, deeds, and coordinate geometry. In new subdivisions they hug the plat; on older rural metes-and-bounds they can be generalized. Zoom level matters: at township scale, lines look clean; at driveway scale, you may see offsets from fences and hedges.
How to find property lines
- Open the county GIS from Platbookmapper.
- Zoom until outlines appear; switch to aerial basemap if available.
- Click the parcel; note bearings only if the county publishes them (many do not).
- For stakes, call a surveyor — or at least compare to the recorded plat.
Property boundary map
A property boundary map in GIS is usually the parcel layer plus labels. Export or print tools (when offered) make a field sketch. Pair it with a compass or handheld GPS when you walk a wooded line between farm and industrial park.
Lot lines vs easements
Lot lines are the fee-simple edges. Easements (utilities, access) may appear as separate overlays or only on the plat. Do not assume a grassy strip is “extra land.”
Lot map & acreage map
A lot map focuses on numbered lots in a block; an acreage map emphasizes area labels for larger rural tracts. Both are still tax-oriented until a surveyor stamps a drawing.
Land map in everyday language
“Land map” is a catch-all search. In practice it means the same county parcel GIS — or a topo atlas for terrain context. Start with parcels; add soils, flood, or zoning layers if the project needs them.
Not a survey. Screen parcel boundaries are not construction stakes. Disputes, fences, and setbacks need recorded plats or a licensed survey.
