Perimeter measurement app for field and parcel boundaries
Area is not enough for many jobs. Fences, borders, irrigation lines and site limits need perimeter length.
Field takeaways
- Perimeter is the total boundary length of a closed polygon.
- Phone GPS is useful for approximate fence and planning work.
- Too many noisy GPS points can inflate perimeter.
- Imported KML/DXF boundaries need CRS checks.
- MapLab Survey keeps perimeter, area, notes and export together.
Why perimeter gets measured
Almost always because somebody has to buy material: fencing, kerbing, cable or irrigation line. That makes accuracy a cost question, not an academic one.
Walking inflates the number
A boundary walked with GNSS carries small deviations that lengthen the perimeter. Drawing corner to corner gives a cleaner figure for a materials order.
Close the ring
An open polygon reports a perimeter that is missing its final side. Confirm the shape closes before reading the value.
Add for corners and slope
Order against the slope distance on rising ground, and add a margin at corners and gates where material is consumed faster than the drawing suggests.
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.
