While many global road maps exist, few include detailed surface information or keep pace with rapid infrastructure change. The new HeiGIT dataset closes this gap by combining 3–4 meter resolution PlanetScope imagery (2020–2024) with deep-learning models to analyze 9.2 million kilometers of major transport routes connecting cities and rural regions. The result is a high-accuracy global classification (89.2%), outperforming widely used open datasets by over 20 percentage points.
