IMA 20200421 vector digital data The hotspot analysis was conducted using the NSM change rate layer, which consists of shoreline change rates calculated with the Digital Shoreline Analysis System version 5.0 (DSAS v5.0) and stored as a new transect layer. Original measurement transects are cast by DSAS from the baseline to intersect shoreline vectors, and the intersect data provide location and time information used to calculate rates of change. These statistics are appended to the rate transect layer.

Any testing on these data should be carried out by end-users to ensure fidelity of relationships. This dataset contains transects with shoreline change rate information generated by the DSAS v 5.0 software application. Transect features generated using DSAS v5.0.20181221.1313. Parameters Used: baseline layer=east1_base, baseline group field=NULL, transect spacing=20 meters, search distance=200 meters, land direction=left, shoreline intersection=seaward, File produced = east1_94_14_200 .For additional details on these parameters, please see the DSAS help file distributed with the DSAS software, or visit the USGS website at: https://woodshole.er.usgs.gov/project-pages/DSAS/ 20200421 09:23:15 Shoreline intersects and rate calculations performed.
