Web-based map for viewing and editing fire hydrants and other firefighting water supply points using OpenStreetMap data. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

HydrantMap (hydrantmap.org) is a web-based application for displaying fire hydrants and other firefighting water supply points using OpenStreetMap data.
The application provides an interactive map with tools for locating, inspecting and maintaining fire water supply information. Users can browse the map without an account. An OpenStreetMap account is required to add or edit objects.
Features
Map display
HydrantMap displays several types of objects mapped in OpenStreetMap:
- Fire hydrants, including underground, pillar, wall and pipe hydrants
- Fire water suction points
- Fire water tanks and reservoirs
- Fire water ponds
- Fire stations
Users can select map objects to inspect their available information. Hydrants have a dedicated detail view showing their mapped properties.
Map tools
The application includes:
- Search for places and addresses
- Browser-based geolocation
- Distance measurement with adjustable measurement points
- Distance radius overlay (200 metres)
- Different map backgrounds, including OpenStreetMap and aerial imagery
- PNG export of selected map areas
- Permalinks for sharing map views
- Fullscreen map display
OpenStreetMap editing
HydrantMap supports direct editing of OpenStreetMap data through an authenticated OSM account.
Users can:
- Add new fire hydrants
- Add suction points and fire water tanks using the desktop toolbar
- Edit existing hydrant information
- Add or update known properties such as hydrant type, diameter, location, pressure, water source, operator and reference number
- Save changes directly to OpenStreetMap
Editing is primarily focused on fire hydrants. Other mapped objects, such as fire stations and fire water ponds, can be viewed but do not have the same editing functionality.
OpenStreetMap integration
HydrantMap uses OpenStreetMap as its data source. Edits are submitted to OpenStreetMap under the authenticated user's account.
The application is intended to support the mapping and maintenance of fire water supply information. Users should only contribute information obtained from their own observations or sources compatible with OpenStreetMap's licensing requirements.
Changes to OpenStreetMap may not appear immediately in the application.
Development
HydrantMap.org is an independent project developed by Fabian Flodman.
The application was inspired in part by the earlier OsmHydrant project, but is a separate implementation.
HydrantMap is under active development.
Limitations
HydrantMap is intended for OpenStreetMap data viewing and maintenance, not for operational emergency response or authoritative fire protection planning.
OpenStreetMap data may be incomplete, inaccurate or outdated. Information relevant to emergency operations must be independently verified using appropriate official sources.
