uMap
Verified working Aug 3, 2026
Create shareable OpenStreetMap-based maps without running GIS software.
uMap is a web tool for building interactive maps on top of OpenStreetMap layers. Users can add markers, lines, and polygons, style those features, import common geospatial files, and share or embed the finished map on another site.
Why it stands out
- Built specifically around OpenStreetMap, making it a natural fit for open mapping projects.
- Supports multiple geospatial import formats instead of requiring users to draw every feature by hand.
- Includes publishing features such as embed codes and shareable maps, not just map editing.
- Open-source project with a hosted instance maintained by OpenStreetMap France.
- Available in a large set of interface languages, useful for international mapping communities.
Good to know
- Primarily centered on OpenStreetMap layers rather than a broad marketplace of proprietary basemaps.
- The page emphasizes map creation and styling, not advanced GIS analysis or desktop-grade geoprocessing.
- Using the public hosted instance means relying on the OpenStreetMap France service rather than running a fully controlled installation.

Community organizers, educators, and local project teams can publish custom map overlays without setting up GIS infrastructure. Build a simple public map of points of interest for an event, guide, or neighborhood project. Import existing GeoJSON, GPX, KML, or OSM data to turn a dataset into an embeddable map. Create themed maps for cycling, hiking, tourism, public-sector, or environmental projects. Browse existing public maps for examples before designing a new one.
OpenStreetMap-based layer selection; markers, lines, and polygon drawing; configurable colors and icons for map objects; map display options such as minimap and user-location behavior; batch import for GeoJSON, GPX, KML, and OSM files; data license selection; sharing and website embedding.
