Web app that generates topographic contour maps (SVG + PNG) from elevation data, using OpenStreetMap for coastlines and place annotations. | ||||||||||||||||||||

TopoLines is an online tool that generates topographic contour maps from real elevation data. It renders contour lines that can be exported as print-ready SVG and high-resolution PNG, for uses such as contour line art, posters, laser-cut and CNC files, and custom hiking maps.
OpenStreetMap usage
TopoLines queries the Overpass API to retrieve OpenStreetMap coastline geometry and place names. Coastline data is used to clip contour lines cleanly at the shoreline, and place names are used to label generated maps.
