How is land measurement done with phone, RTK, KML and MapLab Survey
Land measurement is not just drawing a line on a phone. The target, accuracy and delivery format must be clear.
Field takeaways
- The first decision is purpose: reconnaissance, area, parcel check or stake-out.
- Phone GPS is suitable for approximate work, not legal boundaries.
- RTK needs corrections, fixed solution, antenna height and control.
- KML, DXF, CSV and GeoJSON serve different deliveries.
- MapLab Survey keeps measurements, layers, photos, notes and exports in one project.
Method follows tolerance
Decide what the result has to be accurate to before choosing how to measure. Reconnaissance, an area declaration and a legal boundary sit at three different levels.
Capture the corners
Record a point at each change of direction and let the straight sections run between. Continuous tracking records noise, not geometry.
Check as you go
Measure a known point at the start, and close the polygon at the end. Those two habits catch most of the mistakes that otherwise surface in the office.
Hand it over with context
Coordinate system, date and method belong next to the result. The number alone cannot be verified or reused.
Try these steps on your own phone.
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.
