- For
- Landowners, mapmakers, GIS and CAD users
- Worth noticing
- The page distinguishes output-grid spacing from source resolution and vertical accuracy, and warns against treating contours as a survey.
Field notes
An area can be defined by a rectangle, polygon, typed coordinates, or an imported KML/GeoJSON boundary; imported files are limited to 5 MB and are read in the browser. Free downloads include a 3,998 × 4,096 PNG and GeoJSON with elevation, unit, and index attributes. Pro options include DXF, Shapefile, KMZ, layered SVG, and an 8,000-pixel PNG; the page says these files are built in memory and not stored.
