Image Indexing for Nearshore RestorationMorgan McKenzie and Dan AllenGeog 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?
Data Process Diagram Analyze Attributes (such as % overhanging veg, aquatic, veg, shorline length, etc) Process images (manually or with image processing software) Download image from WAGDA 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
IMAGE Structures Vegetation ID# Name Date Resolution Source ID# Bulkhead Over water structure %Armored ID# Woody Debris # of Clusters % overhanging Vegetation Aquatic vegetation Image Database Image database Location Geomorphic Objects Bch Length ID# Location Latitude Longitude Projection ID# Spit Embayment Erosion Deposits Watershed ID# Beach Length
Conclusions • Indexing images for a specific use is difficult because of the large unique set of content • Completing the data entry is a huge undertaking • Once past the data entry phase, potential for long term time saving use • Image data index model can be used over and over again for new data
