ESS-DIVE Unoccupied Aerial Systems (UAS) Reporting Format v1

Here we present documentation of the ESS-DIVE reporting format for Unoccupied Aerial System (UAS) data and metadata. This reporting format provides guidance to data contributors on how to store data to maximize their discoverability, facilitate their efficient reuse, and add value to individual datasets. For data users, the reporting format will better allow data repositories to optimize data search and extraction, and more readily integrate similar data into harmonized synthesis products. The reporting format provides templates and guidance for the reporting of metadata for UAS experimental campaigns, individual flights, platform and sensor description. To improve data access and discoverability, the reporting format proposes a data description scheme of Levels based on the degree of processing, where Level 0 includes raw data, through to Level 3 being derived data end products. A range of examples of data types for each Level are given, with suggested file naming schemes. The reporting format presented here is intended to form a foundation for future development that will accommodate new UAS technologies and approaches to data access and use in the future. The reporting format documentation is maintained and updated on the ESS-DIVE Community Space GitHub at https://github.com/ess-dive-community/essdive-uas. This data package is the first published version of this reporting format, and comprises a zip file of the complete content of https://github.com/ess-dive-community/essdive-uas v1.0. The zip contains the reporting format description, instructions and variable definitions in GitHub markdown language (*.md) and metadata templates in csv format. The reporting format is designed to be compatible with other ESS-DIVE formats, and it is specifically recommended that this reporting format be used in conjunction with the File-level metadata (FLMD) and comma separated values (csv) reporting formats for submission to the ESS-DIVE repository.本文档针对无人航空系统（Unoccupied Aerial System，以下简称UAS）数据与元数据的ESS-DIVE报告格式进行详细说明。该报告格式为数据贡献者提供数据存储规范指南，以最大化数据可发现性、提升数据高效复用性，并为单份数据集增值。对于数据使用者而言，本报告格式可助力数据仓储优化数据检索与提取流程，更便捷地将同类数据整合为统一的综合成果。本报告格式为UAS实验项目、单次飞行任务、平台与传感器描述的元数据报送提供模板与指南。为提升数据获取效率与可发现性，本报告格式提出基于处理程度的分级数据描述体系：0级为原始数据，最高至3级为衍生最终数据产品。文档针对每个分级提供了多种数据类型示例，并附带推荐的文件命名规范。本次提出的报告格式旨在为未来发展奠定基础，以适配新兴的UAS技术及数据获取与使用方法。本报告格式的文档由ESS-DIVE社区空间GitHub仓库（https://github.com/ess-dive-community/essdive-uas）维护并更新。本数据包为该报告格式的首个正式发布版本，包含https://github.com/ess-dive-community/essdive-uas v1.0的完整内容压缩包。该压缩包包含以GitHub Markdown语言（*.md）编写的报告格式说明、操作指南与变量定义文件，以及逗号分隔值（comma separated values）格式的元数据模板。本报告格式旨在与其他ESS-DIVE格式兼容，且特别推荐在向ESS-DIVE仓储提交数据时，将本报告格式与文件级元数据（File-level metadata，FLMD）及逗号分隔值（comma separated values）报告格式结合使用。
