Map-Tools is an online map assistant that provides utilities such as geometry extraction, geometry viewer, and coordinate conversion. Whether you're a GIS professional, developer, or anyone working with spatial data, this tool makes these tasks easier and more efficient.
- Geometry Extractor: Draw Points, LineStrings, Polygons, and BBoxes, then export them as a coordinate Array, WKT,
or GeoJSON in EPSG:3857 or EPSG:4326. Drag vertices to edit after drawing (Esc cancels a sketch, Backspace removes the
last point), see live length/area measurements, and jump anywhere with the built-in location search. BBoxes also
output their
[xmin, ymin, xmax, ymax]extent. Copy or download any output as a file. - Geometry Viewer: Paste — or import a file (file picker or drag-and-drop) — a coordinate Array, WKT, or GeoJSON,
PostGIS EWKT (
SRID=4326;…) or WKB/EWKB hex, KML, GPX, an encoded polyline (precision 5 or 6), or a[xmin, ymin, xmax, ymax]bbox. Format and projection are auto-detected (an SRID is honored). Visualize it on a map, inspect its measurements and extent, and convert it to Array, WKT, or GeoJSON with one-click copy or download. - Share Links: Every drawn or viewed geometry has a Share link button that copies a link opening the same geometry
in the Viewer. The geometry is compressed into the URL's
#fragment, so it is never sent to a server. - Coordinate Converter: Convert a coordinate between EPSG:3857 and EPSG:4326 — the source projection is auto-detected, "lat, lng" order as copied from Google Maps is supported, and Enter converts instantly.
