Seeking algorithm behind End Point Rate (EPR) to calculate movement of shoreline over period of years?

by Anuja Negi   Last Updated March 13, 2018 07:22 AM

I am analyzing the shoreline change over a period of 20 years(1998-2018). I have following data:

  1. digitized shorelines of 1998, 2003,2008,2013 and 2018
  2. one common baseline for all shorelines
  3. transect lines from baseline to shorelines.
  4. I have the lat/long of the intersection points of transect lines and shorelines.
  5. The distance between shoreline and baseline from the intersection point.

I need to calculate the EPR (End point rate) and NSM (net shoreline movement). My DSAS Tool is not working due to some .dll file missing. I need to figure out the algorithm behind these calculations. Any suggestions?
