Fall 2011 SAV Classification

Description

The sub-aquatic vegitation map for was produced for the SAV Technical Working Group under a cooperative workplan with BP. The SAV map was derived from 0.3 meter resolution visible and near-infrared imagery collected by Aerometric. The imagery was segmented into homogeneous image objects following an object-based image analysis (OBIA) approach. The image objects were subsequently classified using Classification and Regression Tree (CART) statistical analysis. Manual edits based on air photo interpretation were performed to correct obvious errors and refine the map. A draft map was reviewed by USGS personnel and final edits made based on their comments. The polygons were dissolved based on the class assignments and a minimum mapping unit of 4 square meters was enforced.
