Auto Field Maps

Draw around your land and every field is found, measured and numbered for you. Download it as a map, a spreadsheet or for Google Earth.

Find your land on the map, then draw around it.

1Find your land

2Draw around your land

It doesn't need to be accurate. Just go roughly round the outside of your fields, a little beyond the hedges, so every field is inside: each field's own edges are found for you. Click round it on the map, then click the first point again (or press Finish). You can draw more than one area.

    Draw fields, hedges and fences by hand

    A field you draw gets its size straight away. A fence, hedge or wall drawn right across a field splits it in two; otherwise lines you draw are used as field edges the next time you press Auto map fields. Tap any field or line on the map to change its corners, number or delete it.

      +Your own aerial photo (optional)

      Use a newer or sharper picture of your land than the satellite one: a straight-down drone photo, an aerial photo or a mapping file (GeoTIFF). A mapping file places itself. A photo starts in the middle of the map: drag it roughly into place, then press Line it up and it is matched to the hedges and field edges on the map. Your photo is then used to find the fields, and appears in your downloads. It stays on your device.

      This takes a little longer: the lidar for your land is fetched and read.

        Only available once your land is drawn.

        Fences don't show up on maps, photos or lidar. Mark any fences that split a field first (Draw around your land, then Draw fields, hedges and fences by hand), or split the field afterwards with Edit field.

          Choose what to download (tap one to leave it out), then press Download.

          The PDF has your map on the first page and a list of every field, with its number and size, on the second. The spreadsheet opens in Excel or Google Sheets.

          About Auto Field Maps

          Auto Field Maps finds the fields on your land for you: it reads the hedges, fences, walls, tracks and streams already on OpenStreetMap, the hedges and changes of crop colour in the aerial photo, and (at the most accurate setting) the hedges, walls and banks that stand up in the Environment Agency's lidar. In England each field is labelled with its Rural Payments Agency field number.

          Sizes are measured on the map, so they can differ a little from your official records. Check anything that matters against the Rural Payments service.

          It is free and works in your web browser. Your work is kept in your browser and is never sent to us.
