GPS Topography: Land Survey

GPS area measurement and land survey in the field. Capture points with your phone's GPS or a tap on the map and instantly get area, perimeter, closure error and UTM coordinates. Deliver PDF plan sheets and DXF files for AutoCAD without going back to the office. Built for land surveyors, civil engineers, site foremen, farmers and students who need a fast land survey with the device already in their pocket.

HOW YOU MEASURE
• Base point from GPS, typed coordinates or a tap on the map
• Points by GPS, by distance and azimuth (radial) or on the map
• GPS accuracy grade on screen and pole height applied to every point
• Area, perimeter, closure error and UTM/geographic coordinates instantly

FREE, NO ACCOUNT NEEDED
• GPS and map land measurement, up to 2 saved projects
• Export to PDF (watermarked), CSV and DXF
• Offline maps for areas without coverage
• GNSS sky view: visible satellites and signal quality
• Augmented-reality view of your survey

GPS TOPOGRAPHY PRO (monthly or annual subscription; free trial on select plans for eligible users)
Client-ready deliverables
• Watermark-free PDF with scaled plan sheet, coordinate table and your signature block
• Export to KML/KMZ, GeoJSON, GPX, Shapefile, LandXML, GeoPackage, total-station TXT and CoT
• Photos and custom forms on every point

Engineering calculations on site
• Cut and fill volumes
• Contour lines, elevation profile and cross section
• Lot partition and boundary buffer
• Coordinate transformation between EPSG systems

Stakeout and receivers
• Point, line and arc stakeout
• External GNSS receivers over Bluetooth or USB (NMEA) and NTRIP/RTK corrections, depending on your receiver

Also in PRO: unlimited projects, cloud backup, layers, feet units and no ads.

ACCURACY YOU CAN CHECK
Geodesic calculations and coordinate conversions are validated by automated tests against EPSG/PROJ and WGS84 references. Final accuracy depends on your phone's GPS or your receiver. What you see on screen is what you export.

COMPATIBILITY
Import CSV, DXF, GeoJSON, KML and GPX. Files open in AutoCAD, Civil 3D, QGIS, ArcGIS and Google Earth, among others. Brands mentioned belong to their owners and are cited only as compatibility examples.

Available in English, Spanish, Portuguese, French, Arabic and Chinese.
