A Partnership that Works !
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?
ShoreZone is a coastal habitat mapping system that characterizes physical and biological resources of the shoreline.
ShoreZone features:
• georeferenced imagery
• georeferenced data
• searchable database
![Page 8: What is ShoreZone? Part 1 Overview & Description](https://reader035.fdocuments.net/reader035/viewer/2022062408/5681385a550346895da0074d/html5/thumbnails/8.jpg)

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.

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