NC Digital Elevation Model - Slope

A layer showing degrees of slope derived from Digital Elevation Models (DEMs) with a 3ft. grid cell size. Steepness is represented in degrees. The range of values is 0 degrees (flat) to 90 degrees (vertical). The DEM's were created by the NC Floodplain Mapping Program and processed by NC Department of Public Safety - Division of Emergency Management. More information about the data and the methods used to create it can be found by reading about North Carolina's Lidar collection program. County mosaic DEM's can be downloaded from NC OneMap's Direct Data Downloads. Data should not be downloaded using the map on the dataset's item page.本数据集为基于3英尺网格单元尺寸的数字高程模型（Digital Elevation Models，DEMs）生成的坡度图层，以度数表征坡度陡缓程度，数值范围为0°（平坦地表）至90°（垂直地表）。该DEMs由北卡罗来纳州洪水制图项目（NC Floodplain Mapping Program）制作，并经北卡罗来纳州公共安全部应急管理司（NC Department of Public Safety - Division of Emergency Management）处理完成。有关该数据集及其制作方法的详细信息，可查阅北卡罗来纳州激光雷达（Lidar）采集项目相关资料。分县拼接的DEMs可通过NC OneMap直接数据下载（NC OneMap's Direct Data Downloads）渠道获取。请勿通过数据集详情页面的地图下载本数据。
