RCC Orthomosaics, 2017 - 2019

Visible light orthomosaics of the study reaches in Red Canyon Creek were generated from UAV images and Structure from Motion photogrammetry. The orthomosaics show the study areas one year prior to beaver dam analogue (BDA) installation (2017), immediately after BDA installation (2018), and one year after the BDAs had been constructed (2019). These data are used in Davis et al. (2021), Evaluating the geomorphic channels response to beaver dam analog installation using unoccupied aerial vehicles (https://doi.org/10.1002/esp.5180). The rest of the data used in Davis et al. (2021) is available on CUAHSI HydroShare (http://www.hydroshare.org/resource/7c4ae80863174acfb571ccf8bdac8968).红岩溪（Red Canyon Creek）研究河段的可见光正射镶嵌图，由无人机（Unmanned Aerial Vehicle，UAV）影像结合运动恢复结构（Structure from Motion）摄影测量技术生成。该正射镶嵌图覆盖了三个时间节点的研究区域：海狸坝模拟结构（Beaver Dam Analogue，BDA）安装前1年（2017年）、安装后即刻（2018年），以及海狸坝模拟结构建成后1年（2019年）。这些数据被应用于Davis等人2021年发表的研究《利用无人机评估河道地貌对海狸坝模拟结构安装的响应》（https://doi.org/10.1002/esp.5180）。该研究2021年使用的其余数据可在CUAHSI HydroShare平台获取（http://www.hydroshare.org/resource/7c4ae80863174acfb571ccf8bdac8968）。
