    • SpaceNet competition hosts several datasets on roads and buildings. For example, Challenge 3 - Las Vegas, Paris, Shanghai, Khartoum Road Extraction Challenge provides road-centerlines annotation of SpaceNet dataset. It uses the imagery from Challenge 2 (24,586 images of 302,701 building footprints), only tiled into 400m chips (resolution of 1300px x 1300px.
  • [2018-CVPRW2018, DeepGlobe] DeepGlobe 2018: A Challenge to Parse the Earth through Satellite Images paper
    • Road extraction challenge: DigitalGlobe+Vivid images in Thailand, Indonesia, India with 50cm/pixel. Total of 8570 images (6226 training, 1243 validation, 1101 testing).
    • Building detection: the images are taken from 25,586 images of size 650px x 650px
    • Land cover classification: containing 1,146 satellite images of size 2448px × 2448px pixels in total.
