Automating sinkhole identification and classification

Discussion created by pleatofthepants on Apr 21, 2012
I have created a 2m DEM from bare earth lidar points and now need to extract the sinkholes and calculate their spatial properties. I have read of how to do this by writing custom python code but I am pressed for time so I am trying to figure out how to do this using the tools available in ArcDesktop 10 ArcInfo license.

This is what I would like to automate:
Input DEM
Run 3x3 median operator (High Pass Filter)
Create a depressionless DEM by raising cells to their spill elevation
Create DEM with depression cells having their depth value and all non-depression cells have a value of 0
Flow direction
Watershed
Classify depression objects based on spatial attributes (volume, depth, eccentricity, etc...)
