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?

  • If you are seeking an algorithm then what relevance does ArcGIS Desktop have to your question beyond displaying your input data? – PolyGeo Mar 13 '18 at 6:56
  • DSAS Tool is not working due to mclmcrrt78.dll file missing. I am not able to resolve the issue so I thought of moving on and try other alternative. – Anuja Negi Mar 13 '18 at 6:58
  • Have you tried searching Google for algorithm "end point rate", or arcgis "end point rate" if you think the solution may lay there? – PolyGeo Mar 13 '18 at 6:59
  • We see DSAS questions occasionally (gis.stackexchange.com/search?q=dsas) so perhaps where you are stuck with that may be a separate question that you can ask. – PolyGeo Mar 13 '18 at 7:03
  • gis.stackexchange.com/questions/274181/… Yes i already did put a question. I am searching on google too and read many articles regarding the same. I have not got clarity on my doubt. Any information from any medium would be helpful to me. – Anuja Negi Mar 13 '18 at 7:09
