RCC Digital Elevation Models, 2018 - 2019

Digital elevation models (DEMS; 6.9 cm/pixel) of Red Canyon Creek were created using visible light images collected during UAV flights and Structure from Motion photogrammetry. The two DEMs here are from 2018, immediately after the beaver dam analogues (BDAs) were installed, and from 2019, one year after BDA installation. The provided files are ASCII text files that can be easily converted to raster format in ArcMap and ArcGIS Pro. The coordinate system is WGS 84 / UTM Zone 12N (EPSG::32612).

本数据集针对红石溪（Red Canyon Creek）构建了分辨率为6.9厘米/像素的数字高程模型（Digital Elevation Models，DEMs），数据来源于无人机（Unmanned Aerial Vehicle，UAV）飞行任务采集的可见光影像，并通过运动恢复结构（Structure from Motion，SfM）摄影测量技术完成生成。本次提供的两期DEM分别对应2018年（海狸坝模拟设施(Beaver Dam Analogues，BDAs)安装完成后即刻）与2019年（BDAs安装满一周年后）的地形状态。所提供的文件为ASCII文本格式，可在ArcMap与ArcGIS Pro中便捷转换为栅格格式。该数据集采用的坐标系为WGS 84 / UTM 12N带（EPSG::32612）。
