CCA Update Data Products

Using CCA for land cover updating provides a more cost- and time-efficient alternative to complete re-classification. CCA allows first the finding of the areas of change, and then the interpretation and updating of just those areas of change so that no areas are being re-interpreted unnecessarily.

With traditional methodology, the only way to provide updated land cover information is to create entirely new data from more-recent imagery.
