摘要本研究提出了一种地面实况激光雷达数据的采样方法，使研究人员能够在大面积上验证或预测结果的准确性。我们的案例研究集中在尤卡坦半岛Yaxnohcah遗址中心的24平方公里区域。该地区的特点是各种茂密的热带雨林和湿地植被区，道路和小径有限。选择了21个100x100米的区块进行研究，其中包括几个不同植被带的例子。行人调查横断面通过块进行，记录两种类型的错误。第1类错误包括在野外识别的文化特征，但在数字高程模型（DEM）或数字表面模型（DSM）中看不到。第2类错误包括在DEM或DSM上查看时似乎是文化的特征，但由不同的植被特征引起。同时，我们对每个街区进行了广泛的植被调查，确定了主要的物种和楼层高度。结果表明，激光雷达测量数据非常可靠，样本可用于评估更大区域的数据准确性，保真度和置信度。
Abstract This study proposes a sampling method for ground-truthing LiDAR-derived data that will allow researchers to verify or predict the accuracy of results over a large area. Our case study is focused on a 24 km2 area centered on the site of Yaxnohcah in the Yucatan Peninsula. This area is characterized by a variety of dense tropical rainforest and wetland vegetation zones with limited road and trail access. Twenty-one 100 x 100 m blocks were selected for study, which included examples of several different vegetation zones. A pedestrian survey of transects through the blocks was conducted, recording two types of errors. Type 1 errors consist of cultural features that are identified in the field, but are not seen in the digital elevation model (DEM) or digital surface model (DSM). Type 2 errors consist of features that appear to be cultural when viewed on the DEM or DSM, but are caused by different vegetative features. Concurrently, we conducted an extensive vegetation survey of each block, identifying major species present and heights of stories. The results demonstrate that the lidar survey data are extremely reliable and a sample can be used to assess data accuracy, fidelity, and confidence over a larger area.
