Draw a bounding box, convert coordinates, clean up GeoJSON, move between formats, and embed a live map — each one a first-class part of the Spatly studio, running entirely in your browser. When you want more, open your result in the studio in one click.
Draw, fix and inspect geometry in the browser.
Move between GeoJSON, KML, GPX, CSV, Shapefile and WKT.
Shapefile, KML, KMZ, GPX, CSV and WKT in; GeoJSON, KML, GPX, CSV and WKT out — 30 pairs, each with its own page.
Read coordinates, bounds, distance and area precisely.
Draw a rectangle on the map or paste coordinates to get a bounding box in every format: [minX, minY, maxX, maxY], WKT, GeoJSON, CSV, the Overpass/OSM order, plus width, height, area, centre and per-zoom tile ranges. Nothing leaves your browser.
Paste a coordinate in any format — decimal degrees, DMS, UTM, EPSG:3857 metres or geohash — and get every other format back, with a pin on the map. Click the map to set a point, convert a whole list in batch, and copy or download the result. Runs entirely in your browser.
Ship a live map into any page with one line.
