A browser map, with an iPhone app described as coming soon, shows property boundaries and public-land edges against terrain and in 3D.

Landing page captured for the 2026-10-30 issue.

For: Hunters, landowners, and boundary-checking visitors
Worth noticing: Imported boundaries can use GPX, KML, KMZ, or GeoJSON; the page warns phone GPS may be off by 5–15 meters.

Field notes

The browser map lets users click locations in North Carolina, inspect nearby land and boundaries, load their own line files, and preview terrain in 3D. The listed inputs include GPX, KML, KMZ, and GeoJSON; the iPhone version is described as coming soon. Coverage is uneven: public-land data is statewide, while terrain, roads, and trails are specified around Raleigh, Durham, and Chapel Hill.
