DSAS

DSAS generates transects that are cast perpendicular to the reference baseline to intersect shorelines at a user-specified spacing alongshore. Please note that the figure above illustrates the placement of both onshore and offshore baselines as examples. In DSAS v6.0 all baselines in a file must be placed either offshore or onshore, not combined.

DSAS measures the distance between the baseline and each shoreline intersection along a transect, and combines date information, and positional uncertainty for each shoreline, to generate the following change metrics (see DSAS v.5.1 user guide for more detail)
