Survey number on a land photo

For surveyors, real estate teams and landowners who want plot details printed next to the GPS location, in their state's land unit.

In short
  • Stand right on each boundary stone when you shoot it
  • Enter survey number and area in Cent, Guntha, Acre and more
  • Fixlens records; it does not replace a licensed survey

What goes on the stamp

The Modern template in Fixlens prints the details a land photo usually needs:

  • Survey, Khasra, Khata or Patta number
  • Plot area with its unit
  • Facing direction from the compass, with the Vastu zone
  • Your name and a note, such as which boundary stone this is
  • GPS coordinates with accuracy, date and time, and a map

Step by step

  1. Swipe to the Modern template on the camera screen.
  2. Enter the survey number and area in stamp settings and pick the unit.
  3. Walk the boundary. Photograph each corner or boundary stone and note it, for example "Stone B2, north-east corner".
  4. Take one overview from the access road showing the plot and its surroundings.

Land units supported

Units vary by state, and some, like Bigha, have different sizes in different regions. Confirm the local value with the revenue office for anything official.

Tips for boundary photos

  • Stand right at the stone so the coordinates describe that point, not where you parked.
  • Let the GPS accuracy settle. Under trees, wait a little longer.
  • Use degrees, minutes and seconds if your drawings use that format.

Fixlens records what you enter and what your phone's GPS reports. It is not a substitute for a licensed survey or official land records.
