How to measure land area on your mobile

Karnataka LandGrid  |  Updated

Quick answer

On a satellite map, tap each corner of the plot; the app joins the points and shows the area (acres-guntas, square feet) and the length of every side. With survey boundaries switched on you can trace the parcel exactly. Map measurements are approximate; for legal measurement, get a survey done by the survey department.

Measure on the satellite map

  1. Zoom in on the plot until you can see its corners clearly.
  2. Tap each corner in order around the plot. The shape closes and the area appears.
  3. Read the result: area in acres-guntas and square feet, the perimeter, and the length of each side.
  4. Adjust any corner by dragging it, then save or share.

The Karnataka LandGrid app includes this measure tool together with the survey boundaries, and is coming soon to Google Play and the App Store.

Check a plot against its survey number

Switch on survey numbers, tap the parcel to see its approximate area, then measure the part you are buying. If you are buying only part of a survey number, the measured area should match the portion in the agreement and the 11E sketch.

How accurate is it?

  • Accuracy depends on the satellite image and how precisely you place the corners. Expect small differences on small plots.
  • The mapped survey boundary is for reference; it can differ from the RTC extent and from the ground.
  • For registration or disputes, use a measurement by a licensed surveyor or the survey department.

To convert between units, use the acres and guntas converter.
