Announcing SpaceNet 8: Flood Detection Challenge Using Multiclass Segmentation

The SpaceNet 8 Flood Detection Challenge will focus on infrastructure and flood mapping related to hurricanes and heavy rains that cause route obstructions and significant damage.
  • How have algorithms that extract buildings and roads improved since SpaceNet was launched, and how can top algorithms from previous challenges be leveraged?
  • What is the impact on performance for a multiclass feature extraction challenge — i.e., buildings and roads?
  • How accurately can roads obstructed by flood waters be characterized from pre-event road detections and post-event satellite imagery?
These before and after satellite images captured by WorldView-2 show the destruction in Barataria, La., following Hurricane Ida in August 2021.
