Free Online GeoJSON Freehand Draw Tool
Draw freehand lines and shapes on a map. Hold and drag to draw naturally, release to finish. Export as GeoJSON LineString. Free, no upload.
What is Freehand?
Freehand drawing allows you to draw lines naturally by holding the mouse button and dragging across the map. The tool records every mouse movement point to create a dense LineString. Freehand is ideal for sketching rough boundaries, tracing features from imagery, or creating organic shapes without placing individual vertices.
How to draw
To draw Freehand, select the Freehand mode. Press and hold the mouse button on the map, drag to draw, and release to finish. The tool captures all intermediate points for a smooth line.
Common uses
Freehand drawing is used for quick sketching, tracing features from satellite imagery, creating approximate boundaries, educational demonstrations, and any scenario where precise vertex placement is not required.
GeoJSON output
Each geometry is converted to standard GeoJSON (RFC 7946) format with WGS84 coordinates. Copy or download the output for use in any GIS or mapping application.
All geometry types
This tool supports all 12 geometry types: Point, Polyline, Polygon, Freehand, StraightArrow, DiagonalArrow, DoveTailArrow, DoubleArrow, ClosedCurve, Sector, GatheringPlace, and PlotLineString.
