GeoJSON map studio processes your input in this browser. Inputs and results are excluded from analytics. Recent tools save tool names, visit counts and last-visit times. Saved tools store only their names. Draft saving is optional and stays on this device; delete saved text with the draft controls. Loading text from a URL is optional and contacts that server; its URL and your IP address are visible to the server. An optional “Use in” action keeps a handoff in this tab. The next tool removes it on arrival and ignores it if more than a minute has passed.

Copy link includes the inputs you choose to share in the address. Anyone with that link can reopen them. Files and generated results are excluded. Password and key tools share settings only.

GeoJSON map studio explained

Paste GeoJSON to draw points, lines, polygons or geometry collections and save the drawing as SVG. Coordinates are longitude first, latitude second. Polygon holes stay visible, and collection features share one fitted view.

Next: JSON formatter

A worked example

The position [0, 0] is longitude zero, latitude zero. A single point appears at the center of the preview. North is up.

Next: Place coordinate lookup

Before you use the result

A longitude/latitude plot without a base map. It does not preserve real-world areas or distances, check polygon topology or show elevation. Split lines and polygons at the antimeridian first. Legacy projected coordinates must be converted before use.
