Image analysis project Michelle Bachman, NEFMC Staff, Habitat PDT - PowerPoint PPT Presentation

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
