Draw on Map

Draw freehand, lines, shapes and markers on a real map, see each line's length and each shape's area, label them and download the drawing as GeoJSON, KML or GPX.

Your browser asks before sharing your position. Coordinates and typed text are sent only to the lookup services named on the result; this site stores nothing.

Width

Press and drag on the map to draw. Switch to another tab to pan the map.

Open a GeoJSON, KML or GPX file to keep drawing on it

Lengths are geodesics on WGS84; areas on the ellipsoid (authalic latitude). Your drawing stays in your browser until you download it — reloading the page clears it. Map tiles: OpenStreetMap.

How to draw on a map

Go to the place. Search an address or use your location.
Pick a drawing tool. Freehand (press and drag), line or shape (click points), or marker.
Choose a colour and width. Then draw. Finish lines and shapes with the button.
Label and measure. Each item gets a label field and its length or area.
Download. Save the drawing as GeoJSON, KML (Google Earth) or GPX, or open a file to keep editing.

What people draw on maps

Planning a route

Sketch a walking, running or cycling route and see its length.

Marking a property

Outline a lot and read its acreage.

Explaining directions

Draw the way to a hidden entrance or parking spot.

Event layouts

Mark stages, tents and parking on a site.

Hunting and fishing spots

Mark areas and points to load into a GPS.

Classroom maps

Students trace rivers, borders or routes.

Delivery zones

Draw the area you serve.

Field notes

Sketch where something was seen.

How the drawing is measured and saved

The map is OpenStreetMap. Every point you draw is a latitude and longitude on WGS84, the GPS datum, so the downloaded file lines up in Google Earth, GIS software and GPS devices.

Line lengths are summed geodesic distances (Vincenty). Shape areas are computed on the ellipsoid with authalic latitudes, so they are not distorted by the map's Mercator projection.

Freehand strokes are thinned to drop points that are almost on top of each other. Nothing is uploaded: the drawing stays in your browser until you download it.

Frequently asked questions

How do I move the map while freehand drawing?

Switch to another tool (line, shape or marker) to drag the map, then switch back.

Can I open the drawing in Google Earth?

Yes, download KML and open it in Google Earth or import it into Google My Maps.

Will my drawing be saved?

Only if you download it. Reloading the page clears it.

Can I edit an existing file?

Yes — open a GeoJSON, KML or GPX file and draw on top of it.

How accurate are the measurements?

As accurate as where you click. Zoom in for precise corners.
