Land measurement app for area, perimeter, coordinates, KML and reports
A land measurement app should do more than show GPS. It should connect area, perimeter, coordinates, KML, DXF, photos and reports.
Field takeaways
- MapLab Survey supports points, lines and polygons.
- It supports field calculations such as area, perimeter, slope, profile and volume.
- KML, DXF, GeoJSON and CSV serve different delivery needs.
- Phone GPS is approximate; external RTK is for precise work.
- Layers, photos and notes make the data understandable.
Who uses a land measurement app?
A farmer checking a field's area, a construction crew, GIS staff, survey technicians and field teams on infrastructure, agriculture and energy projects all reach for the same app. The shared need: getting field data to the office intact, in a form that still makes sense six months later. Measuring is the easy part; remembering what was measured, by which method and in which coordinate system is what separates a field tool from a calculator with a map.
What MapLab Survey covers
- Area and perimeter; distance, routes and GPS track recording.
- Opening and sharing KML/KMZ; exporting DXF, CSV and GeoJSON.
- Photo-tagged locations and field notes.
- Coordinate systems such as WGS84 and UTM, and reporting.
Before the first point
Do not start measuring the moment the app opens. Name the project, create layers by feature type with understandable names, pick the coordinate system and note the data source. That minute of setup in the field saves hours of sorting in the office.
Accuracy, honestly
The phone's own GPS works at the metre level, enough for reconnaissance, planning and approximate areas. Centimetre accuracy takes an external RTK GNSS receiver over Bluetooth — same app, same workflow, the hardware makes the difference. Stating which accuracy you worked at is as valuable as the figure itself.
Photos and notes
A measurement with a photograph of the location survives a dispute; one without usually does not. Attach a short note to anything ambiguous — which corner was which gets answered in the field, not reconstructed in the office.
Finish with the export
Reopen the file on the map and check positions before exporting. Choose the format for the recipient — DXF for CAD, GeoJSON for GIS, CSV for spreadsheets, KML for quick viewing — and put the coordinate system in the filename. The same project also produces a photo-backed report, so geometry, notes and images travel as one delivery.

MapLab Survey handles RTK/GNSS point capture, drawing, area and volume calculations and coordinate conversion, then exports to DXF, KML/KMZ, GeoJSON, Shapefile, GeoPackage, NCZ or CSV. Capture, calculation and export work offline. Live NTRIP corrections and online basemaps need a connection.
