This collection includes two indices:

1. Ridge Top Flatness: A topographic index designed to identify high flat areas at a range of scales
   
2. Valley Bottom Flatness: A topographic index designed to identify areas of deposited material at a range of scales based on the observations that valley bottoms are low and flat relative to their surroundings and that large valley bottoms are flatter than smaller ones. Zero values indicate erosional terrain with values 1 and larger indicating progressively larger areas of deposition.
