Measuring a field boundary on a satellite map with live area and per-segment distances Measurement result with area, perimeter, and GPS accuracy estimate

Five ways to capture

Pick the method that fits the field — switch anytime.

Placing precise points with the centered crosshair reticle

Tap the map

Tap each corner on satellite imagery. The fastest way when you can see the boundary.

Crosshair

Pan the map under a fixed reticle and drop points exactly where you want them.

Walk the boundaryGPS

Walk around the field while smart filtering keeps only usable GPS fixes.

Corner pointsGPS

Stand at each corner and capture an averaged GPS point. Best accuracy for regular fields.

Record a routeGPS

Walk, ride, or drive while the app records the distance you travel.

See it in action

Short clips, real app — no mock-ups.

Tap corners on the map — area, perimeter, and per-edge distances update live.

Open a saved measurement and export a PDF report, KML, GeoJSON, or GPX in two taps.

Circles, rectangles, and line corridors for the shapes a polygon can't catch.

Features

Honest accuracy

Every GPS result carries a ± estimate derived from the actual fix quality. No pretending centimeters from a phone.

Real geometry

Geodesic math on the WGS84 ellipsoid, multiple regions with true holes, circles, rectangles, and corridors.

Your units

Acres, hectares, m², ft², plus regional units like 亩 and 坪. Tap any result to switch units in place.

Fix it afterwards

Drag any vertex with a magnifier loupe, undo and redo freely, and get warned live if the shape crosses itself.

Organized fieldwork

Collections, tags, favorites, photos on every measurement, search, and a 30-day recycle bin.

Import & export freely

KML, GeoJSON, and GPX go both ways — bring measurements in from other tools and take yours anywhere. Never paywalled.

The usual annoyances — fixed

“Want to export your own data? That’ll be $40 a year.”

PDF, KML, GeoJSON, and GPX export are free forever. Your data was never ours to sell back to you.

“An ad banner over the map, right where you’re tapping.”

No ads, no account, no upsell screens — the whole app is the free version.

“Claims centimeter accuracy, then the boundary drifts across the road.”

Bad fixes are filtered out, corner points are averaged, and every result states its honest ± range.

“One mistap and an hour of walking is gone.”

Drafts autosave continuously, undo and redo work everywhere, and deleted items rest in a 30-day recycle bin.

Professional reports

Every measurement turns into a clean PDF report: an annotated satellite map, results with their honest ± uncertainty, coordinates, and your photos and notes. Collections export as a combined report with numbered maps.

Files open directly in QGIS, Google Earth, and handheld GPS units — and GPX goes both ways, in and out.
