Enhanced Terrain Imagery of the Wellsboro 30 x 60 Minute Quadrangle from Lidar-Derived Elevation Models at 3-Meter Resolution

This imagery dataset consists of 3-meter resolution, lidar-derived imagery of the Wellsboro 30 x 60 minute quadrangle in Pennsylvania. The source data used to construct this imagery consists of 1-meter lidar-derived digital elevation models (DEMs). The lidar source data were compiled from different acquisitions published between 2019 and 2020. The data were processed using geographic information systems (GIS) software. The data is projected in WGS 1984. This representation illustrates the terrain as a hillshade with contrast adjusted to highlight local relief according to a topographic position index (TPI) calculation.

本影像数据集涵盖宾夕法尼亚州威尔斯伯勒（Wellsboro）30角分×60角分标准图幅的3米分辨率激光雷达（LiDAR）衍生影像。制作该影像的源数据为1米分辨率激光雷达衍生数字高程模型（DEMs）。本次所用激光雷达源数据整合自2019至2020年间发布的多批次采集成果。数据集通过地理信息系统（GIS）软件完成处理，采用WGS 1984坐标系进行投影。本可视化成果以晕渲图形式呈现地形，并通过调整对比度以突出局部地势起伏，对比度调整依据地形位置指数（TPI）计算结果完成。
