Fieldplot

Fieldplot — GPS field measurement, editing, and reporting, in your pocket.

Walk the boundary of a field, plot, or land parcel and Fieldplot calculates the area and perimeter live using your phone's GPS. Place points manually without visiting the location, drag any point (even GPS-captured ones) to correct it, and insert new points between existing ones — Fieldplot is a lightweight editor, not just a recorder. Most land-measuring apps only record a GPS track and give you no way to fix a bad reading; Fieldplot lets you correct any point, anytime.

Measure & edit
• Measure area & perimeter by walking with GPS
• Place points manually anywhere on the map, no need to be on-site
• Drag any point to edit it — GPS, manual, or already-edited points all stay editable
• Insert a new point between two existing ones with a single tap
• Name any point (e.g. "NW boundary corner") and attach a photo to it
• Street and satellite map views, plus on-screen zoom controls
• Choose Metric or Imperial units

Organize multiple parcels
• Keep several shapes in one project — useful when one piece of land is really several parcels
• Compare two measurements side-by-side to see exactly how much a boundary changed over time

Convert & report
• Coordinate Converter: switch between Decimal Degrees, DMS, and UTM — one at a time or in batch from a CSV file
• Generate a client-ready PDF report with a map snapshot, area/perimeter, a full points table, your photos, and any custom fields you add (surveyor name, client, site, etc.)

Import & export everywhere
• Import existing surveys from SHP (zipped Shapefile), KML, GPX, or GeoJSON
• Export your work to SHP, KML, GPX, GeoJSON, or plain CSV
• Save projects locally and reopen them anytime — undo/redo every edit

Built for:
Land surveyors, farmers, agricultural consultants, land assessors, real estate scouts, and anyone who needs a quick, on-site area estimate and a professional report to hand over — without carrying survey-grade equipment.

Please note: Fieldplot is an estimation tool, not a certified survey instrument. Typical phone GPS accuracy is ±3–5 meters, so results are approximate and should not be used for legal, title, or boundary-dispute purposes.
