Description
Gene Smith and Anthony Sanchez defined a Morphology Index (MI) based upon a numeric classification of crater walls, central peaks and floors. This is functionally equivalent to classifying craters into the types defined by Wood and Anderson, 1982. MI increases with crater diameter as craters change from simple to complex shapes.
MI and its components are given in the Moon WIki for the few hundred craters cataloged by Smith and Snachez and Smith and Hartnell (1978)
Additional Information
MI is the addition of scores for TSI + FI + CPI.
TSI - Terrace-Shape Index - the form of crater terraces/slumps and the crater floor diameter / crater diameter (CFD/CD).
FI - Floor Index - floor texturing.
CPI - Central Peak Index - morphology and number of central peaks.
This table shows the scoring for each index.
