Supplemental Information

Relationship to other Datasets: This data set may have a number of additional attributes in the future which may be derived from other layers such as HYDRO25, TOPO25, ROAD25, LCCVEG25-100, EVC100, and TREE100_90. These attributes will describe seasonal river regime, landform, access, and coastal vegetation. Current Design Issues: The coastal trace was partially acquired from the available 1:25,000 tiles in the L25 corporate library layer hydro25, the remainder was digitized from 1:25,000 stable base maps. Future Design Issues: As the official version of the coastal trace is completed for the whole state and is entered into the corporate library it should be adopted. Related Documents: None
