Why Professionals Choose GpsField

Save time and work more efficiently with powerful geospatial tools, accurate measurements, and actionable insights - built for the real world.

Parcel Precision

Millimeter polygon accuracy, even on curved terrain.

Traditional web map tools calculate simple flat Euclidean planar formulas, introducing up to 15% error over large parcels. GpsField runs geodesic geodesy accounting for earth curvature, elevation contouring, and magnetic declination.

Answers & Transparency

Frequently Asked Questions

Got questions about accuracy, offline usage, or file exports? We have clear answers.

GpsField executes the Karney geodesic algorithm on the WGS-84 terrestrial ellipsoid rather than basic flat-plane planar projections. This means over large acreage (from 1 acre to 50,000+ hectares), error remains under 0.02%. When walking perimeter boundaries using phone GNSS or external RTK Bluetooth rovers, accuracy reaches sub-decimeter precision.
