{"url":"/dataset/roadtracer","name":"RoadTracer","full_name":null,"description_markdown":"**RoadTracer** is a dataset for extraction of road networks from aerial images. It consists of a large\r\ncorpus of high-resolution satellite imagery and ground truth\r\nroad network graphs covering the urban core of forty cities\r\nacross six countries. For each city, the dataset covers a region of approximately 24 sq km around the city center. The satellite imagery is obtained from Google at 60 cm/pixel resolution, and the road network from OSM.\r\n\r\nThe dataset is split into a training set with 25 cities and a\r\ntest set with 15 other cities.\r\n\r\nSource: [RoadTracer: Automatic Extraction of Road Networks from Aerial Images](/paper/roadtracer-automatic-extraction-of-road)\r\nImage Source: [Bastani et al](https://paperswithcode.com/paper/roadtracer-automatic-extraction-of-road)","description_withheld":null,"homepage":"https://roadmaps.csail.mit.edu/roadtracer","introduced_date":null,"introduced_date_note":null,"introduced_by":{"paper":"/paper/roadtracer-automatic-extraction-of-road","title":"RoadTracer: Automatic Extraction of Road Networks from Aerial Images","first_author":"Favyen Bastani","url":null},"license":{"name":"Unknown","url":null},"modalities":[{"name":"Images","url":"/datasets/modality/images"}],"tasks":[{"name":"Semantic Segmentation","url":"/task/semantic-segmentation","datasets_with_task":"/datasets/task/semantic-segmentation"},{"name":"Chinese Reading Comprehension","url":"/task/chinese-reading-comprehension","datasets_with_task":"/datasets/task/chinese-reading-comprehension"},{"name":"Audio Question Answering","url":"/task/audio-question-answering","datasets_with_task":"/datasets/task/audio-question-answering"},{"name":"Disaster Response","url":"/task/disaster-response","datasets_with_task":"/datasets/task/disaster-response"},{"name":"graph construction","url":"/task/graph-construction","datasets_with_task":"/datasets/task/graph-construction"}],"languages":[],"variants":["RoadTracer"],"data_loaders":[],"num_papers_in_archive":39,"source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28"},"benchmarks":[],"papers_with_a_benchmark_row":[],"syntology_totals":{"read_at":"2026-09-24T18:15:14+00:00","papers_with_samples":0,"samples_harvested":0,"samples_ran":0,"samples_unverified":0,"pointer_only_for_licence":0,"papers_with_no_sample_that_ran":0,"note":"the per-paper counts above, summed; not a rate"},"papers_note":"The archive never published its papers-using-dataset list; these are papers with a leaderboard row on this dataset's benchmarks."}
