mapbox/robosat

Based on the README, here's a technical summary: Implements a complete end-to-end pipeline using fully convolutional neural networks for pixel-level segmentation, with specialized tools for data preparation (downloading imagery from Mapbox APIs, extracting OSM geometries), model training on GPU/CPU, and post-processing that transforms segmentation outputs into cleaned GeoJSON features while handling Slippy Map tile boundaries. Works with standardized tile formats (256x256 pixels) to abstract geo-referenced imagery, and provides extensibility for custom data sources and feature types beyond the built-in extractors.
