The Nearshore Geospatial Framework provides a connection between data based on the ShoreZone shoreline (including coastal data from the ESRP Beach Strategies project) and nearby inland and aquatic spatial data. The purpose of this framework is to enable Chinook salmon restoration and protection. The Nearshore Geospatial Framework consists of polygons with one edge coincident with the the ShoreZone shoreline, such that GIS users can easily link coastal data with upland and aquatic data. These polygons are constructed from Beach Strategies shoretypes and net shore-drift cells. In the Nearshore Geospatial Framework, "net shore-drift cells” include each contiguous stretch of left-to-right or right-to-left net shore-drift, as well as areas of no appreciable drift.These aquatic shoretype polygons share a boundary with the WDFW ShoreZone shoreline and extend waterward to a depth of 10 meters. Lateral boundaries of these polygons are established by breaks between shoretypes, as delineated in the ESRP Beach Strategies project (Coastal Geologic Services, 2017). Attributes related to the presence of herring within each aquatic shoretype polygon were added using data from the WDFW Forage Fish Spawning Survey (2017). All work was completed in the NAD_1983_HARN_StatePlane_Washington_South_FIPS_4602_Feet projected coordinate system.This project was made possible with funding and support from the Puget Sound Partnership. |
