GPS Field Measure - GLand Pro

GLand Pro measures land area, distance and perimeter with your phone's GPS: walk the field boundary, or tap the corners on a satellite map. It is a GPS area measure, acre calculator and field survey app in one. One-time purchase: no ads, no subscription, no account. Your fields stay on your phone, and the GPS area measure works offline.

GPS area measure: walk or tap the map
• Measure area, perimeter, distance, circles and points
• Walk or drive the boundary: GPS records the points, also with the screen off
• GPS corners mode averages several positions for each corner
• Tap mode and crosshair mode for exact points on the map
• Type or paste coordinates (lat/lon, DMS, UTM, MGRS and more)
• Live area, perimeter, side lengths and angles while you measure
• Area accuracy shown as ± from the GPS accuracy of each corner
• Edit shapes: move, insert and delete points, undo, cut holes

Land area calculator in acres, hectares and local units
The acre calculator shows the area in all units at once: acre, hectare, m², km², ft², yd², rood, perch, decare (dönüm), bigha, katha, decimal, cent, guntha, marla, kanal, rai, ngan, square wah, mu, pyeong, feddan, jerib, sotka, arpent (Quebec), sào, mẫu and công (Vietnam), relung (Malaysia), ubin, tumbak and bata (Indonesia) and more, with state variants of bigha and katha for India.

RTK GPS and GNSS survey
• Connect a Bluetooth RTK GPS or GNSS receiver (NMEA) for a precise GPS survey
• Built-in NTRIP client: RTK corrections over your phone's internet
• See the fix type (RTK fixed or float), satellites, HDOP and accuracy
• Every corner keeps its GNSS quality: source, fix, satellites and accuracy
• PDF survey report with an accuracy certificate page
• Stake-out: walk to typed points with an on-screen arrow

Field tools
• Split a field with a line, or divide it into equal parts
• Merge fields and add setback buffers
• Navigate to a field or to any corner
• Calculators: land value, seed and fertilizer amounts, fence length and posts
• Tree count for a planting layout in the real field shape
• Earth volume: area × depth, or cut and fill to a level
• Elevation of a point and elevation profile of a line
• Compass with true and magnetic north
• AR corner finder: see marked corners in the camera picture (ARCore phones)

Made for
Farmers and agronomists, land surveyors, real estate agents, engineers, foresters, and anyone who needs to measure land.

About accuracy
Phone GPS accuracy is often 3-5 m outdoors with a clear view of the sky, and the app shows it live. For centimeter-level work, use an RTK receiver. Live maps, elevation and NTRIP need internet; GPS measuring, saved fields and offline maps work without it.

GLand Pro: a GPS area measure and land area calculator to measure land, then save, export and survey your fields.
