Loxahatchee River Seagrass Communities (2004)

This polygon feature class identifies the extent and distribution of seagrass communities within the Central Embayment of the Loxahatchee River in June 2004. Seagrass data was photointerpreted from 1:5,000 scale natural color aerial diapositives. Mapping was performed by Avineon, Inc. Positional accuracy for this data meets or exceeds the USGS National Map Accuracy Standards (NMAS). Digital linework was reviewed over the USGS DOQQ's and on a Zeiss P3 Analytical Stereo Plotter. These data were collected for monitoring purposes and will be used to track the health of the seagrass communities in this area. Monitoring of Seagrass communities through mapping and photo interpretation provides an effective and economical means for measuring ecological change over time. Detectable changes will result from natural succession, as well as anthropogenically altered forcing functions. Detecting these changes using historical photograph sets can provide a measure of how these factors affect the seagrasses within the Central Embayment of the Loxahatchee River.
