Quick start. Choose a background map, add objects from the Add Object tools, then select any object to edit its coordinates, style, buffers, notes, and layer. Use the Layers section to reorder, hide, lock, or select the active drawing layer.
Coordinates. Search, coordinate input, and coordinate editing accept decimal degrees, DMS, and MGRS. The Settings panel controls how coordinates are displayed and copied.
Measurements. Distances and areas are calculated geodesically with Turf/Leaflet helpers and are intended for field planning and OSINT sketching, not survey-grade engineering. Circles and buffers are generated on the globe rather than as simple screen pixels.
Attribution. Background maps retain their source attribution in the map and exported interactive HTML. Respect OpenStreetMap, OpenTopoMap, Esri, CARTO, and any loaded data licenses.
Shortcuts. Draw with 1 point, 2 line, 3 polygon, 4 circle, 5 text box, 6 unit. Use S for search, E edit points, M move, Enter finish drawing, Delete remove, Ctrl+Z undo, Ctrl+S save GeoJSON, Ctrl+C copy object, Ctrl+V paste object at cursor, C copy object coordinates, Shift+C copy cursor coordinates.
