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 from OpenStreetMap contributors.

Search millions more geographic features

This Hugging Face release is one downloadable dataset from the broader EmbedEarth 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 — programmable infrastructure for Earth
  • Geographic Feature List — browse geographic features available through EmbedEarth
  • Developer Documentation — APIs, SDKs, tools, guides, and examples
  • Geographic Search SDK — 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:

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 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.

Data sources and attribution

This dataset was prepared and distributed by EmbedEarth from data contributed to OpenStreetMap.

OpenStreetMap data is available under the Open Database License (ODbL) 1.0. When using or redistributing the data, retain the OpenStreetMap attribution and follow the applicable ODbL requirements. Record-level media or third-party links may have additional terms set by their original providers.

Suggested attribution:

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.
