Fundamentals

Stratification and post-classification sorting

  • Incorporation of ancillary data before, during and after classification
  • Prior to classification enables stratification of image data set (e.g., vegetation -elevation associations)
  • As a layer within the classification process
  • Refinement of classification results using ancillary data layer and established set of rules
