Offroad-global-nav Geospatial Dataset

Overview

This repository contains the dataset introduced in:

“Learning Traversability-Aware Global Planners for Long Horizon Off-Road Navigation”

The dataset is designed to support long-range off-road navigation using multi-modal geospatial data, combining large-scale overhead sensing with real-world human driving behavior.

Unlike traditional off-road datasets that focus on local perception, this dataset enables global planning over kilometer-scale environments.


📊 Dataset Summary

  • Scenes: 299 geographically diverse locations (more will be added)
  • Coverage: ~1,244 km²
  • Human driving data: ~1,130 km of GPS trajectories

Modalities

  • 🛰️ Satellite imagery (GeoTIFF)
  • 🌐 Aerial LiDAR point clouds (LAZ)
  • 🗺️ OpenStreetMap vectors (OSM XML)
  • 📍 Human trajectories (KML)

Each scene is fully geo-referenced and co-registered.


🗺️ Geographic Coverage

The dataset spans diverse terrain types across the United States, including:

  • Deserts
  • Grasslands
  • Forests
  • Mountains
  • Quarries and mines

🧱 Data Structure

🔍 Modalities Explained

Satellite Imagery

High-resolution RGB imagery capturing:

  • Vegetation
  • Trails
  • Water bodies
  • Terrain appearance

LiDAR Point Clouds

Dense aerial LiDAR (5–27 pts/m²) providing:

  • Elevation (height)
  • Surface normals (slope)
  • Intensity (surface reflectivity)

OpenStreetMap (OSM)

Vector priors including:

  • Roads and trails
  • Waterways

Used as weak semantic supervision.


Human GPS Trajectories

Real-world driving paths used as:

  • Implicit supervision for traversability
  • Ground truth for path preference
