Lake Okeechobee Littoral Vegetation (2010)

This polygon feature class defines the extent and type of littoral vegetation within the western marsh portion of Lake Okeechobee circa 2010. A grid-based approach was used to identify the dominant vegetation type within each 100 sq meter (1 hectare) area. Dominant (VegLabel1) vegetation classes were tallied up to calculate the dominant class' contribution toward the total percent of all the classified grid cells. SFWMD conducted an internal accuracy assessment of the map. The assessment was conducted both on the softcopy stereo veg mapping work station and in the field via helicopter flights. A 100+ grid cells were visited via helicopter to identify the ground conditions as well as the probability that the species had established due to rapid fluctuation of lake stage and may or may not have been present when the aerial imagery was acquired in May 2010. The aerial imagery used in the mapping was acquired by Aerial Cartographics of America, Inc.
