Description
An algorithm that normalizes the lighting to detect changes between two different SPOT or Pléiades images from the same collection. It returns a change map. Change detection can be used for vegetation management, urban planning, construction, fire risk estimation, land use management, forestry, and infrastructure monitoring.
