1,747 township records on device
The Illinois pack is part of Legal Land Locator's 30-state U.S. PLSS index. Search a written description, use individual fields, reverse-estimate from a map tap or ask for the legal location near your current position.
Built around the field job
After lookup, inspect section and aliquot outlines, copy the canonical description or coordinates, measure distance and bearing, save the site with access notes and open navigation. Reopened sites retain their grid overlays.
Offline means the grid, not every map tile
The transformed township index, parsing and geometry are bundled with the app. Apple Maps supplies the background basemap and satellite imagery, so those tiles can still need service unless cached.
Navigation estimate—not a survey
PLSS grid output is useful for route planning and field orientation. Verify critical locations with official records and a licensed surveyor.
Read the description before the field visit
Follow a township, range and section example and compare PLSS with Canadian DLS descriptions.
Questions about Illinois lookup
Does Legal Land Locator cover Illinois?
Yes. The installed Illinois pack contains 1,747 BLM-derived township records for offline PLSS lookup.
Does the result establish a property boundary?
No. Results are navigation estimates and do not replace official records or a licensed survey.
Does lookup need cellular service?
The legal-description conversion and grid geometry run on the device. Background map imagery may need a connection unless cached.
