Nigeria Railway Network (HOTOSM Lines, Points & Polygons)

This dataset provides an integrated view of Nigeria's railway network, including tracks (lines), stations (points), and railway-related structures (polygons). Data is sourced from Humanitarian OpenStreetMap Team (HOT) and OpenStreetMap (OSM).

Dataset Details

• Total Records: 1,472 records (1,315 lines, 138 points, 19 polygons)
• Total Track Length: ~3,405 km
• Format: Apache Parquet
• Geographic Coverage: Nigeria
• Source: HOTOSM / OpenStreetMap

Features

Feature	Type	Description
name	string	Name of the station or track segment
railway	string	Type of railway feature (rail, station, platform, etc.)
feature_type	string	Type of OSM feature ('point', 'line', or 'polygon')
latitude	float64	Representative Latitude (centroid for lines/polygons)
longitude	float64	Representative Longitude (centroid for lines/polygons)
length_km	float64	Length of the segment in kilometers (for lines)
geometry_wkt	string	Well-Known Text (WKT) representation of the geometry
osm_id	string	OSM ID
source	string	Data source

Processing & Sorting

• Track Lengths: Calculated using UTM Zone 32N (EPSG:32632) projection for accurate measurement.
• Centroids: For lines and polygons, a representative point (centroid) was calculated to provide a consistent location interface.
• Geometries: Preserved as WKT strings.
• Sorting: Sorted by name and railway type.

Usage

import pandas as pd
df = pd.read_parquet("nigeria_railways.parquet")
# Filter for stations
stations = df[df['railway'] == 'station']
