Manatee Carcass Recovery Locations in Florida

GIS shapefile of recovered or verified manatee carcass locations within Florida from April 1974 through to the latest available spatially verified data. Locations are based both on coordinates provided by field staff (gathered either by GPS or by using navigation charts to ascertain latitudes and longitudes) and maps provided by the field staff. FWRI GIS staff in the Marine Mammal subsection verify that the provided coordinates match the intent of the plotted location. Points representing carcass locations were entered into a GIS using a digital shoreline basemap taken largely from NOAA navigation charts (1:40,000) and from USGS quadrangles (1:24,000) or in reference to the latest available NAIP aerial imagery when the data were processed. The scale is considered to be 1:40,000.本数据集为1974年4月起至最新经空间核验的可用数据为止，佛罗里达州境内已回收或经核实的海牛尸体点位地理信息系统形状文件（GIS shapefile）。点位信息同时来源于野外作业人员提供的坐标（通过全球定位系统（GPS）采集，或借助航海图确定经纬度），以及野外作业人员提交的纸质地图。佛罗里达鱼类与野生动物研究所（FWRI）海洋哺乳动物分部的GIS工作人员会核验所提供的坐标与标注点位的意图是否一致。尸体点位通过数字岸线底图录入地理信息系统（GIS），该底图主要取自美国国家海洋和大气管理局（NOAA）1:40000比例尺航海图、美国地质调查局（USGS）1:24000比例尺标准地形图幅，或在数据处理阶段参考最新可用的美国国家农业航空影像计划（NAIP）航空影像。本数据集默认比例尺为1:40000。
