Free Online GeoJSON DoubleArrow Draw Tool
Draw double arrow symbols on a map with arrowheads on both ends. Click 3-4 control points. Export as GeoJSON. Free GIS arrow tool.
What is DoubleArrow?
DoubleArrow creates a bidirectional arrow symbol with arrowheads at both ends. It is defined by 3-4 control points that shape the arrow body. Double arrows represent two-way movement, exchange, or mutual interaction in tactical mapping and GIS visualization. The arrow has a distinctive double-headed shape.
How to draw
To draw a DoubleArrow, select DoubleArrow mode. Click 3-4 control points on the map. The first and last points become the two arrowhead positions, and the middle points control the arrow body curvature. Double-click to finish.
Common uses
Double arrows are used for two-way routes, exchange symbols, mutual support indicators, bilateral movement, and any GIS visualization requiring bidirectional flow representation.
