Abstract

Unmanned Aerial Systems (UAS) are capable of improving the efficiency of acquisition and providing fine spatial scale data for sustainable resource management. In this paper we begin by describing differences between UAS airframes, their successes and limitations, and list contemporary research applications. UAS compatible sensor technologies are discussed, including passive and active sensors. Finally, we detail a case study where UAS updated an Enhanced Forest Inventory (EFI) for a study area in interior British Columbia. Airborne Laser Scanning (ALS) from 2013 and Digital Aerial Photogrammetric (DAP) point clouds acquired using a UAS from 2015 were used to estimate individual tree height and volume increments. A total of 246 trees were detected using Canopy Height Models (CHMs) with 70% of these trees being matched in the ALS and DAP data sets. Mean tree growth between 2013 and 2015 from the CHM and 95th percentile of height (P95) was estimated at 0.68 ± 0.05 and 0.50 m ± 0.05 m, respectively. Similarl...

用于精确森林清查目的的无人机系统：综述和案例研究

无人机系统能够提高获取效率，并为可持续资源管理提供精细的空间尺度数据。在本文中，我们首先描述了无人机机身之间的差异、它们的成功和局限性，并列出了当代的研究应用。讨论了与无人机兼容的传感器技术，包括无源和有源传感器。最后，我们详细介绍了一个案例研究，其中无人机更新了不列颠哥伦比亚省内陆研究区的增强森林清单（EFI）。2013年的机载激光扫描（ALS）和2015年使用无人机获取的数字航空摄影测量（DAP）点云用于估计单个树木的高度和体积增量。使用树冠高度模型（CHM）共检测到246棵树，其中70%的树在ALS和DAP数据集中匹配。2013年至2015年间，CHM和身高第95百分位（P95）的平均树木生长量估计分别为0.68±0.05和0.50 m±0.05 m。类似。。。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
