snippet: Creation of a 2020 seagrass map from 1:24,000 scale natural color aerial photography that is consistent with and aligned to the previous 2016 seagrass map for the Springs Coast. This data was produced for the SWFWMD's "2020 Districtwide Seagrass Mapping" project.

description: <DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>The Southwest Florida Water Management District (SWFWMD) is responsible for the protection and management of natural systems and water quality within its geographic boundaries. One component of evaluating the ecological health of coastal ecosystems is to map and monitor submerged aquatic vegetation (SAV) communities. This project is a continuation of previous efforts to determine the status and trends (if any) of SAV resources in the coastal waters of the District. The results of this effort will be used to determine the performance of ongoing efforts to improve water quality and quantity in coastal waters of the District.The dataset serves as documentation of the seagrass habitat within Anclote River, Pithlachascotee River, Aripeka River, Weeki Wachee River, Chassahowitzka River, Homosassa River, Crystal Bay, Withlacoochee River, Waccasassa Bay and their respective offshore areas as it existed in January 2020. Seagrass data were photointerpreted from 2020 1:24,000 scale natural color aerial photography and classified using the SWFWMD modified FLUCCS classification system. Horizontal accuracy of meets NMAS for 1:12,000 scale maps. The minimum mapping unit for classification was 0.25 acres.</SPAN></P></DIV></DIV></DIV>
licenseInfo: <DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>The positional accuracy of this data meets USGS NMAS for 1:12000 scale maps. This data has a minimum classification accuracy of 90% for all categories. Mapping conventions applied to the delineation and classification of seagrass categories were: 1) Outer boundaries of beds are more important than internal structure (patchiness, shapes of sand patches within beds). 2) Outer boundaries of beds are more important than density categorization within beds. 3) Minimum Mapping Unit (MMU) is 0.5 acre for all benthic features and 0.25 acre for oysters.</SPAN></P></DIV></DIV></DIV>
