Works without internet
GPS recording, area calculation and the PDF report all work offline. The map background needs data only the first time you view an area.
Features
Every feature is visible in the app. Locked ones show which plan includes them.
Corner averaging
Stand still at a corner for a few seconds and the app averages many GPS readings into one steadier point.
Never lose a walk
Surveys autosave as you move. If the phone restarts or the battery dies, you continue from where you stopped.
Your local units
Acres, guntas, cents, square yards (gajam), ankanam, grounds, hectares — every result is shown in all of them.
Honest GPS quality
The app shows the accuracy your phone reports and warns you before you save a weak measurement.
Edit corners afterwards
Drag a corner to the right spot. The original walk is kept and the report says it was adjusted.
Photos, notes and premium PDF
Attach field photos and notes, and export KML, GeoJSON or GPX for Google Earth and GIS tools.
Teams and branded reports
Staff accounts, survey assignments and PDFs with your business name and logo.
What phone GPS can and cannot do
A phone usually knows its position within about 3 to 5 metres under open sky. On a field of an acre or more that gives a useful estimate. On a small house plot the same error is a large share of the plot, so the app warns you and a tape measure will serve you better.
Land Area Survey estimates area from phone location data. It is not an official government, cadastral or legally certified survey.
- Measure under open sky, away from tall buildings and thick tree cover.
- Hold the phone, do not keep it in a pocket.
- Pause a few seconds at each corner.
- Walk the boundary twice and compare.
