Software, data and services
This tool is based on and works thanks to products/services of the following projects or companies: Leaflet, D3.js, Axis Maps, Mapbox, Mapzen, OpenStreetMap and Google Maps.
Use the square icon tool to the right to choose an area that you wish to map. You can use the pencil and box tool to edit the area or move the mapped area around. If you would like to delete the area choose the trash can icon to start over.
Choose the unit of measure [meters, feet] that you wish to map with. Then choose a contour intreval appropriate for the property you are mapping. We recommend starting with a 1m - 2m [3ft - 6ft] contour interval.
