Title
Maryland Archived Submerged Aquatic Vegetation - SAV 2019 [Maryland]
Description
The Chesapeake Bay SAV Coverage was mapped from digital multispectral imagery with a 25cm GSD to assess water quality in the Bay. Each area of SAV was interpreted from the rectified imagery and classified into one of four density classes by the percentage of cover. The SAV beds were entered into an SDE GIS feature class using the quality control procedures documented below. The dataset contains all SAV areas that were identified from the areas flown. Some areas that are presumed to contain no SAV were not flown. Some small beds, particularly along narrow tributaries may not have been distinguishable on the aerial photography. This is a MD iMAP hosted service. Find more information at https://imap.maryland.gov .
