This dataset mapped 8 types of intertidal and shallow subtidal vegetation along saltwater shorelines in Skagit County and part of Island County in 1996 using an airborne multispectral scanner.  This is one element of a larger dataset that includes substrate type, wave & current energy, water regime and tidal datum lines as well as an ArcGIS layer file.  The complete dataset (all layers) can be accessed under "Download Data".
