Preface: SpaceNet LLC is a nonprofit organization dedicated to accelerating open source, artificial intelligence applied research for geospatial applications, specifically foundational mapping (i.e. building footprint & road network detection). SpaceNet is run in collaboration with CosmiQ Works, Maxar Technologies, Intel AI, Amazon Web Services (AWS), Capella Space, Topcoder, and IEEE GRSS.

The SpaceNet 6 challenge is officially live, and offering $50,000 in cash prizes to our top participants! In the SpaceNet 6 challenge, participants are asked to automatically extract building footprints with computer vision and artificial intelligence (AI) algorithms using a combination of Capella Space synthetic aperture radar (SAR) and electro-optical satellite imagery from Maxar. The challenge will run from March 16th until May 1st. Top participants will be invited to share their work at CVPR EarthVision in Seattle, Washington on June 14th, 2020.

Register and compete in the challenge on TopCoder:
