How to walk a field boundary with GPS track, area, photo notes and checks
Walking a field boundary is practical for reconnaissance and approximate area checks, but it is not a legal cadastral boundary by itself.
Field takeaways
- Walking measurement is useful for reconnaissance and approximate area checks.
- Tree cover, valleys, buildings and phone GPS quality can affect the line.
- Parcel boundary and actual use boundary may differ.
- Photo notes document corners, gates and unclear sections.
- MapLab Survey keeps track, polygon, area, photos and export together.
Walking records reality
Following the boundary on foot captures the irregular corners and the places where the fence has moved. It also records every wobble of GNSS noise.
Corners beat continuous tracking
Stop and record a point at each corner rather than logging continuously. The polygon is cleaner and the perimeter is not inflated.
Walk the line, not the fence shadow
Keep a consistent side of the fence and note which side you walked. A metre of offset all the way round is a visible area error.
Close and compare
Return to the starting corner and check the closure, then compare the result with any registered figure before drawing conclusions.
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.
