Common questions about Montana land GIS

Is Montana parcel GIS accurate enough for surveying or deeds?

No. Montana State Library states its statewide parcel and public lands GIS—the MSDI Cadastral parcel program—is for informational use only—not for legal, engineering, or surveying purposes. Polygon boundaries can lag deeds, split lots, exempt transfers, or rural fence lines.

Does mapped public land guarantee I can hunt or camp there?

Separate rules apply for Wilderness, national parks, grazing closures, firearm restrictions, motorized travel, closures for wildfire safety, leased state trust parcels, tribal boundaries, nuances of enrolled Block Management parcels, conservation easements, and local ordinances.

What is shown in the Conservation Easements layer?

MSL maps easements voluntarily recorded between landowners and qualifying agencies or land trusts on private parcels. Showing an easement does not grant public recreation rights—consult the steward organization for permissible uses.

How often are Montana parcel records updated?

Montana parcels are maintained on roughly a monthly statewide GIS cycle mirrored on State Library MapServer services plus FTP snapshots. Operational delays still happen; verify parcels that matter on the Montana Cadastral GIS viewer or your county assessor map.

Why keep parcel linework toggled off by default?

Statewide parcel rendering is heavier than thematic public-lands overlays. Showing parcels only once you zoom in keeps the Treasure State viewer responsive while you pan across Montana on phones and laptops.

Why is the PLSS township grid off by default?

The township-and-section overlay is visually dense statewide and pulls extra MSDI tiles. Turn it on when you want approximate survey subdivisions alongside parcels or public lands.
