Walk a parcel boundary with phone track and photo notes
Walking a parcel boundary is a practical way to understand the ground before making decisions.
Field takeaways
- A walking track records occupation and field observation.
- Parcel KML can be used as reference.
- Phone GPS is not legal boundary setting.
- Photos document fences, walls, ditches and roads.
- MapLab Survey keeps track, reference and notes together.
What a walking check gives you
Seeing a parcel on the map is one thing; walking the ground is another. Use lines, old fences, stone walls, ditches, tracks, tree rows and the neighbour's use marks reveal themselves on foot. None of it replaces the official boundary, but it sharpens field judgement and improves decisions about buying, leasing or fencing.
The flow with MapLab Survey
Load the parcel reference as a KML/KMZ layer. Start GPS track recording and walk the boundary. At corners, fence turns and ambiguous spots, record a point plus a photo. When the walk ends, your track and the parcel line sit on the same map — where they agree and where they part is visible at a glance.
Reading the gap between track and reference
A metre-level parallel offset is usually phone GPS accuracy; a single-corner jump is signal loss (under trees, against buildings); but a systematic, growing separation may be telling you the use line genuinely differs from the parcel line. To tell the three apart, re-measure suspicious corners standing still, with averaging.
Record what matters
Not every fence post — every decision point: corners, turns, where the neighbour's use begins, gates, crossings, anything that looks contested. Photos saved with coordinates mean that months later, "where was that fence?" has an answer in the archive.
What the result is for — and not for
A walking check is a reconnaissance and decision tool: it shows what needs settling by official survey. It resolves no boundary dispute and produces no registrable data. But when you go to the licensed survey, you arrive with track, photos and notes in hand — and that shortens the most expensive part of the process.
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.
Frequently asked questions
