Dataset of building footprints for the United States
Top 21.2% on sourcepulse
This repository provides a comprehensive dataset of computer-generated building footprints for the entire United States, aimed at researchers, developers, and organizations involved in geospatial analysis, urban planning, and disaster response. The dataset offers over 129 million building footprints in GeoJSON format, derived using advanced computer vision techniques, with a focus on improving the OpenStreetMap ecosystem.
How It Works
The building footprint generation involves a two-stage process: semantic segmentation using an EfficientNet backbone with a combination of supervised and unsupervised training, followed by a novel polygonization method that approximates pixel predictions into polygons by incorporating a priori building properties. This approach aims to achieve higher quality and more accurate polygon representations compared to traditional methods like Douglas-Peucker.
