Image analysis project Michelle Bachman, NEFMC Staff, Habitat PDT Chair

Habitat Committee Meeting August 18, 2016

Materials/information

 Document 2a

 Interpretation of Council problem statement  Summary of previous habitat vulnerability work  Summary of available imagery/data with maps  Approach for this new analysis

Objectives

 Refine habitat maps available for Great South Channel

and Georges Shoal HMAs

 Gather data from images re percent cover of gravels  Confirm or gather data on presence of particular sizes of

gravel (pebble, cobble, boulder)

 Confirm or gather data on epifauna, tag images with

particular long-lived species

 Plan is to use digital imagery vs. video; many of these

images have been previously analyzed and are in the existing SMAST database, but some have not been

Progress/timeline

 Have images and data – obtained from SMAST this spring  Have been collaborating with them on how to approach

problem and how they have already analyzed these images

 Have done preliminary image analysis to determine

methodology and make tradeoffs about time per image vs. expected results

 Next steps are to actually analyze each image (collaboration

w/GARFO HCD), then generate various habitat mapping layers that can be overlaid and used during alternatives development
