Transcript of Image Indexing for Nearshore Restoration Morgan McKenzie and Dan Allen Geog 469.
Project Goals
• Create an Image Data Index Model • For nearshore restoration ecologists– Provide search tool for research time
saving– Images show important landscape
attributes: shore forms, watersheds, vegetation, structures, etc
– Index provides way to find scientific research question desired attributes
Background
• Puget Sound Nearshore Restoration Project, Research group
• Client: Miles Logsdon, Restoration Ecologist– Also Matt Parsons of UW Libraries and WAGDA
• Implement restoration projects and monitor their success/failures to improve
• Examples of restoration projects: – Remove bulkheads, plant overhanging vegetation
Index of Images for Restoration
• See potential areas of restoration• Monitor areas with implemented
restoration project• Potential Scientific Research
Questions include:–How much vegetation?– Depositional or erosional shoreline?– Shoreline before/after a structure
removal?– Shoreline before/after an event?

WAGDA
Process images
(manually or with image processing software)
Analyze Attributes (such as %
overhanging veg, aquatic, veg, shorline length, etc)
Data Entry
For PSNRP analyze
geomorphic objects, woody
debris, % of beach armored
Project Results
• Created a image data index model database
• Discovered which attributes were important and why
• Made database searchable by attributes
