RoadTracer

RoadTracer 是一个从航拍图像中提取道路网络的数据集。它由大量高分辨率卫星图像和地面实况道路网络图组成，覆盖了六个国家的四十个城市的城市核心。对于每个城市，数据集覆盖了市中心周围约 24 平方公里的区域。卫星图像来自谷歌，分辨率为 60 厘米/像素，道路网络来自 OSM。数据集分为包含 25 个城市的训练集和包含 15 个其他城市的测试集。

RoadTracer is a dataset dedicated to road network extraction from aerial images. It consists of a large corpus of high-resolution satellite imagery and ground-truth road network maps, covering the urban cores of forty cities across six countries. For each individual city, the dataset spans an area of approximately 24 square kilometers surrounding its downtown district. The satellite imagery is sourced from Google, with a resolution of 60 cm per pixel, and the road network data is derived from OpenStreetMap (OSM). The dataset is partitioned into a training set including 25 cities and a test set containing the remaining 15 cities.
