Click the map to place each corner of your survey area, in order.
0 points placed.
Area is computed with a local flat-earth projection centered on your polygon — accurate for survey-sized areas (a drone mission site), not intended for country-sized shapes.
How it works
Click each corner of your survey area on the map, in order, to build a polygon — or paste coordinates directly if you already have them from another tool. Area and perimeter update as you go.
Limitations
Area uses a local flat-earth approximation centered on your polygon, accurate for typical drone survey sites (well within 1% for areas up to several km across) but not intended for very large or near-polar shapes.
