The ShoreZone Alaska team was the recipient of the

2009 Coastal America Spirit Award

The national award is for “action-oriented, results-driven collaboration process dedicated to restoring and preserving coastal ecosystems and addressing critical environmental issues.”

what is shorezone
What is ShoreZone?

ShoreZone is a coastal habitat mapping system that characterizes physical and biological resources of the shoreline.

ShoreZone features:

  • georeferencedimagery
  • georeferenced data
  • searchable database

Standardized Coastal Mapping System

where is shorezone
Where is ShoreZone?

ShoreZone includes:

  • all ~ 5,000 km Washington
  • all ~ 40,000 km British Columbia
  • ~ 45,000 km Alaska (in progress; 59%)

Almost 100,000 km of contiguous coastline has been mapped – from the Columbia River mouth to Bristol Bay, Alaska.

ShoreZone Method:Coastal Imagery

  • Mapping is based on video and still imagery:
  • - low-altitude flights of < 200m
  • zero tides or lower
  • oblique camera view- spatially-referenced

Biobands in ShoreZone

A bioband is species assemblage with a characteristic colour and across-shore elevation.
