+# Underground Fire Hydrants (OSM) - 30,000-record Geospatial Sample
+
+A free, ready-to-use sample of **30,000 geolocated underground fire hydrants** (current openstreetmap snapshot), published by **[Outerview](https://www.outerview.ai)**.
+
+Underground fire hydrants mapped by OpenStreetMap contributors, with coordinates and the original OSM tags preserved.
+
+> **This is a 30,000-record sample** of a much larger collection (about 1,089,000 source records). Need the full dataset, other places or years, or live search? See the [Outerview atlas](https://www.outerview.ai/atlas).

+## Quick start
+
+```python
+from datasets import load_dataset
+
+ds = load_dataset("parquet", data_files="hf://datasets/Outerview/underground-fire-hydrant/data.parquet", split="train")
+print(ds)
+print(ds[0])
+```
+
+```python
+import pandas as pd
+import json
+
+df = pd.read_parquet("hf://datasets/Outerview/underground-fire-hydrant/data.parquet")
+df["properties"] = df["properties"].apply(json.loads)
+df[["latitude", "longitude"]].describe()
+```
+
+## Search millions more geographic features
+
+Outerview provides developers and AI systems access to **millions of geographic features and geolocated imagery** spanning infrastructure, places, roads, buildings, nature and community issues.
+
+<!-- outerview-tools:start -->
+## Build with Outerview
+
+- [Geographic Feature List](https://www.outerview.ai/atlas) — browse geographic features available through Outerview
+- [Outerview](https://www.outerview.ai/) — programmable infrastructure for Earth
+- [Developer Documentation](https://www.outerview.ai/docs) — APIs, tools, guides, and examples
+- [SDK](https://www.outerview.ai/docs/sdk) — build geographic capabilities directly into applications
+- [CLI](https://www.outerview.ai/docs/cli) — work with geographic search and spatial data from the terminal
+- [MCP](https://www.outerview.ai/docs/mcp) — connect geographic search and spatial tools to AI agents
+<!-- outerview-tools:end -->
+
+## Use cases
+
+- Emergency-response and fire-safety coverage analysis
+- Insurance and risk modelling
+- Water-network and infrastructure planning
+- Training detection and geolocation models
+
+## Schema
+
+| Column | Type | Description |
+| --- | --- | --- |
+| `id` | string | Stable identifier for the record in the source table. |
+| `sample` | boolean | Reserved flag for optional image samples; false for source-table exports. |
+| `latitude` | float64 | Latitude in decimal degrees (WGS 84). |
+| `longitude` | float64 | Longitude in decimal degrees (WGS 84). |
+| `geometry_wkb` | binary | Record geometry encoded as Well-Known Binary for spatial workflows. |
+| `media_url` | string | URL of associated imagery when available; usually empty for this dataset. |
+| `attribution` | string | Attribution text for the contributing source. |
+| `source` | string | Source or provider label. |
+| `properties` | string | JSON-encoded object with the source-specific fields (see Properties). |
+
+## Properties
+
+The `properties` column is a JSON string holding the original source attributes. The most common keys in this sample:
+
+| Key | Example value |
+| --- | --- |
+| `osm_id` | `10159498218` |
+| `tag_name` | `fire_hydrant:type` |
+| `label_name` | `underground` |
+| `fire_hydrant:type` | `underground` |
+| `emergency` | `fire_hydrant` |
+| `fire_hydrant:position` | `sidewalk` |
+| `survey:date` | `2018-09-27` |
+| `water_source` | `main` |
+| `flow_rate` | `122` |
+| `couplings` | `1` |
+| `note` | `National-Land Numerical Information (Public Faci` |
+| `addr:street` | `Stubaier Höhenweg (Nr. 4)` |
+
+Keys vary by record and source; not every field is populated for every row.

+## Methodology
+
+Records are exported directly from the Outerview geographic index, ordered by identifier and capped at 30,000 rows. Coordinates are WGS 84. Source fields are preserved in `properties` without reinterpretation. Inclusion means a record appeared in the contributing public dataset; it was not independently verified.
