NC Digital Elevation Model - Shaded Relief

A shaded relief map derived from Digital Elevation Models (DEMs) with a 3ft. grid cell size. A vertical exaggeration factor of 3 used for visual effect. 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.本数据集为基于网格单元尺寸为3英尺的数字高程模型（Digital Elevation Models, DEMs）生成的晕渲地貌图。为优化视觉效果，采用了3倍的垂直夸大系数。这些DEMs由北卡罗来纳州洪泛区制图项目（NC Floodplain Mapping Program）制作，并经北卡罗来纳州公共安全部应急管理分局（NC Department of Public Safety - Division of Emergency Management）完成后期处理。有关该数据集及其制作方法的更多信息，可查阅北卡罗来纳州激光雷达（Lidar）采集项目的相关资料。分县镶嵌DEMs可从NC OneMap的直接数据下载板块获取。请勿通过数据集详情页中的地图进行数据下载。
