| # Emergency Fire Hydrant Dataset - Global Fire Safety Infrastructure Data - EmbedEarth |
|
|
| This dataset maps emergency fire hydrant features from OpenStreetMap. A fire hydrant is a mapped connection to a water supply that can support firefighting operations. The records provide a geographic starting point for infrastructure analysis, emergency-service mapping, and data-quality work. |
|
|
| This release contains geolocated records from 2025 and is provided as a sample of a much larger dataset of mapped features. |
|
|
| Prepared and distributed by **[EmbedEarth](https://embed.earth)** from **[OpenStreetMap contributors](https://www.openstreetmap.org/copyright)**. |
|
|
| ## Search millions more geographic features |
|
|
| This Hugging Face release is one downloadable dataset from the broader **[EmbedEarth](https://embed.earth)** geographic index. EmbedEarth provides developers and AI systems with tools for searching and working with geographic features, places, infrastructure, and other observations of the physical world. |
|
|
| ### Build with EmbedEarth |
|
|
| * **[EmbedEarth](https://embed.earth)** — programmable infrastructure for Earth |
| * **[Geographic Feature List](https://www.embed.earth/catalog/features)** — browse geographic features available through EmbedEarth |
| * **[Developer Documentation](https://www.embed.earth/docs)** — APIs, SDKs, tools, guides, and examples |
| * **[Geographic Search SDK](https://www.embed.earth/docs/sdk/search)** — search geographic features and regions programmatically |
| * **API** — integrate geographic search and spatial data into applications |
| * **SDK** — build geographic capabilities directly into applications |
| * **CLI** — work with geographic data from the terminal |
| * **MCP** — connect geographic search and spatial tools to AI agents |
|
|
| ## Search the physical world |
|
|
| The same geographic infrastructure used to create this dataset can support searches such as: |
|
|
| ```text |
| fire hydrants near schools in Boston |
| hydrant coverage around downtown Toronto |
| emergency infrastructure in Los Angeles |
| fire hydrants near industrial areas in Houston |
| ``` |
|
|
| ## Dataset overview |
|
|
| This dataset focuses on **emergency fire hydrants** represented in OpenStreetMap. Each record is a geolocated map feature with source attribution and, where available, additional tags such as names, addresses, references, operators, websites, access details, and feature-specific values. |
|
|
| Mapped emergency fire hydrants and related water-access points used by fire services, where those features are recorded in openstreetmap. |
|
|
| ## Use cases |
|
|
| ### Public-safety mapping |
|
|
| Map fire-hydrant coverage alongside roads, buildings, fire stations, and other emergency infrastructure. |
| ### Emergency-response analysis |
|
|
| Explore proximity, access, and network relationships relevant to response planning. |
| ### Municipal asset research |
|
|
| Compare mapped hydrant attributes and coverage across neighborhoods or service areas. |
| ### Infrastructure risk analysis |
|
|
| Combine hydrant locations with buildings, parcels, hazards, and population data. |
| ### OpenStreetMap quality checks |
|
|
| Review completeness and consistency of fire-hydrant tags and supporting attributes. |
|
|
| ## Schema |
|
|
| The downloadable Parquet and CSV files use a normalized schema. Source-specific attributes are preserved inside the JSON-encoded `properties` field rather than expanded into separate top-level columns. GeoJSON exposes the same record attributes alongside its geometry. |
|
|
| | Column | Type | Description | |
| | --- | --- | --- | |
| | `id` | string | Stable identifier for the exported record. | |
| | `sample` | boolean | Whether this record was selected for the optional image archive sample. | |
| | `latitude` | float64 | Latitude in decimal degrees using WGS 84 when a valid location is available. | |
| | `longitude` | float64 | Longitude in decimal degrees using WGS 84 when a valid location is available. | |
| | `geometry_wkb` | binary | The record geometry encoded as Well-Known Binary for spatial workflows. | |
| | `media_url` | string | URL for associated imagery or other visual media when available. | |
| | `attribution` | string | Attribution information carried into the exported record. | |
| | `source` | string | Source or provider associated with the observation. | |
| | `properties` | string | JSON-encoded object containing source-specific OpenStreetMap attributes. | |
|
|
| ### Source-specific properties |
|
|
| The `properties` field preserves additional OpenStreetMap tags associated with each feature. Exact keys vary by record and region; common examples include: |
|
|
| | Property | Description | |
| | --- | --- | |
| | `osm_id` | OpenStreetMap object identifier when supplied. | |
| | `fire_hydrant:type` | Hydrant type when mapped. | |
| | `fire_hydrant:position` | Position or placement information when supplied. | |
| | `fire_hydrant:diameter / water_source` | Hydrant or water-source attributes when mapped. | |
| | `operator / ref` | Responsible organization or asset reference when available. | |
| | `address` | Address or location text when supplied. | |
|
|
| Not every property is populated for every record. |
|
|
| ## Download |
|
|
| The dataset is available in Parquet, GeoJSON, and CSV formats: |
|
|
| * [Parquet](https://huggingface.co/datasets/EmbedEarth/emergency-fire-hydrant/resolve/main/data.parquet) |
| * [GeoJSON](https://huggingface.co/datasets/EmbedEarth/emergency-fire-hydrant/resolve/main/data.geojson) |
| * [CSV](https://huggingface.co/datasets/EmbedEarth/emergency-fire-hydrant/resolve/main/data.csv) |
|
|
| **Parquet** is recommended for analytics, Python workflows, DuckDB, and large-scale processing. **GeoJSON** is useful for GIS software and web maps. **CSV** is convenient for tabular analysis and interoperability. |
|

|
| ## Methodology and limitations |
|
|
| Records were exported from an OpenStreetMap snapshot for 2025. A mapped hydrant is not a guarantee that the asset is accessible, operational, supplied with water, or suitable for a particular response. Field verification and local authority data are required for operational decisions. |
|
|
| OpenStreetMap coverage and tagging vary by place and contributor. Geographic absence should not be interpreted as real-world absence, and mapped presence should not be treated as an independent inspection or operational certification. |
