Experimental data of The effect of building geometry on the size of aeolian deposition patterns: scale model experiments at the beach

Experimental data of scale experiments performed at the beach. Two series of experiments were performed with cuboid scale models of various sizes, to determine how the size of aeolian depositon and erosion patterns around beach buildings depends on building geometry. Series A consisted of cuboid scale models of buildings, placed at the beach for approximately 1 day. These scale models ranged in size from 0.3x0.5x0.3 m (WxLxH) to 1x2x0.6 m. Measurements were taken at the end of each day (each experiment). Serie B consisted of a shipping container (2.5x12x2.5 m) and a small scale model (0.5x2x0.5 m), placed simultaneously at the beach for more than two months. Measurements were taken at six different days during this period. Deposition and erosion around buildings are measured using structure-from motion (SfM) photogrammetry. Data contains: Raw photos used for SfM photogrammetry Photogrammetry files Digital elavation models (DEMs) and orthophotos of the deposition and erosion around scale models. Processed data from the automatic detection of deposition edges: binarized orthophotos (deposition/rest) and the edges of the deposition areas Time lapses of the the experiments Wind speed and direction measurements Measured deposition sizes

本数据集为海滩现场缩尺实验的实测数据。为明确海滩建筑周边风积（aeolian deposition）与侵蚀格局的规模如何随建筑几何形态变化，研究采用多种尺寸的长方体缩尺模型开展了两组对照实验。
A组实验采用长方体建筑缩尺模型，于海滩布设时长约1天，模型尺寸范围为0.3×0.5×0.3 m（宽×长×高）至1×2×0.6 m，每日（单次实验）结束后开展测量工作。
B组实验同时布设了一个海运集装箱（2.5×12×2.5 m）与一个小型缩尺模型（0.5×2×0.5 m），于海滩放置时长超两个月，实验期间共在6个不同日期开展测量。
建筑周边的风积与侵蚀情况通过运动恢复结构（structure-from motion, SfM）摄影测量法进行测定。本数据集包含以下内容：
1. 用于SfM摄影测量的原始影像照片
2. 摄影测量原始文件
3. 缩尺模型周边风积与侵蚀区域的数字高程模型（digital elevation models, DEMs）与正射影像图
4. 用于自动识别风积边界的处理后数据：二值化正射影像（区分风积区与非风积区）和风积区域边界矢量数据
5. 实验过程延时摄影序列
6. 风速与风向实测数据
7. 实测风积规模数据
