Draw the outline of a field, paddock, or plot on satellite (with place names) or OpenStreetMap, see area and perimeter in your units, and — when you sign in — save farms, field notes, simple crop lines, and tasks. The map asks for your location to centre on you when permitted; otherwise it falls back to a default view. Maps load from public CDNs so the tool stays light on the server; only your saved data is stored in Your Brand.
Use the polygon tool on the left to draw. Default view is satellite with place names; switch to OpenStreetMap in the top-right if you prefer. Edit corners with the edit tool after drawing. Guest measurements are in your browser; saved data is on the account after you sign in.
Click a task to mark done. Shift+click to delete.
Export all your saved fields for GIS as GeoJSON: use the API (signed in) action=export or the button when added.
