Overmap: Map with OSM Data

Build custom map layers from live OpenStreetMap data with Overmap. Turn Overpass results into clear overlays, mark important places, and shape routes or field notes in one flexible workspace. LIVE MAP LAYERS Turn Overpass results into map layers you can shape and reuse. See the places and features that matter while you plan. Keep each map project organized in one place. Export or import maps as JSON whenever you need to move work around. CUSTOM OVERLAYS Add points, lines, circles, rectangles, and labels to any map. Place shapes precisely with coordinate picking. Draw long-distance paths and bearings with great-circle lines. Tune colors, widths, fills, and notes to match your map. Overmap is ideal for planning field work, sketching routes, and turning OpenStreetMap data into personal map layers you can actually use.
