mDRONES4rivers-project: UAV-imagery of the project area Nonnenwerth at the Rhine River, Germany

Spatially and temporally high-resolution data was acquired with the aid of multispectral sensors mounted on UAV and a gyrocopter platform for the purpose of classification. The work was part of the research and development project ‘Modern sensors and airborne remote sensing for the mapping of vegetation and hydromorphology along Federal waterways in Germany’ (mDRONES4rivers) in cooperation of the German Federal Institute of Hydrology (BfG), Geocoptix GmbH, Hochschule Koblenz and JB Hyperspectral Devices. Within the project period (2019-2022) data was collected at different sites situated in Germany along the Rivers Rhine and Oder. All published data produced within the project can be found by searching for the keyword ‘mDRONES4rivers’. In this dataset, the following UAS data and metadata of the project site ‘Nonnenwerth’ (center coordinates [WGS84]: 50.637541°N, 7.208834°E; area: 8 ha) at the Rhine River in Germany is available for download: • Multispectral orthophotos (GeoTiff; 6 bands: B, G, R, Red-Edge, NIR, Flag; camera: Micasense; resolution: 25 cm; abbreviation: MS_RAW) • RGB orthophotos (GeoTiff; 3 bands: R, G, B; camera: Phantom; resolution: 25 cm; abbreviation: PH_ORTHO) • Digital Surface Models (GeoTiff; 1 band; camera: Phantom; resolution: approx. 5 cm; abbreviation: PH_DEM) • associated Technical Reports (PDF; technical metadata concerning data acquisition, and processing using Agisoft Metashape, 1x for multispectral orthophotos, 1x for RGB-orthophotos + digital surface model) The above-mentioned files are provided for download as dataset stored in one directory per season depending on the date of data acquisition (e.g. mDRONES4rivers_NW_UAV_2019_01_Winter.zip = projectname_projectsite_platform_year_no.season_name.season). To provide an overview of all files and general background information plus data preview the following files are stored in the info.zip folder: • Overview table and metadata of the above-mentioned data (xlsx) • Summary (PDF, Detailed description of sensors and data acquisition procedure, 1x for multispectral orthophotos, 1x for RGB-orthophotos + digital surface models) Note: The data was processed with focus on spectral information and not for geodetic purposes. Georeferencing accuracy has not been checked in detail.本数据集借助搭载于无人机（Unmanned Aerial Vehicle, UAV）和旋翼机（gyrocopter）平台的多光谱传感器采集得到，具备时空高分辨率特性，用于分类任务。本工作隶属于德国联邦水文研究所（BfG）、Geocoptix GmbH、科布伦茨应用科技大学（Hochschule Koblenz）与JB Hyperspectral Devices联合开展的研发项目“德国联邦航道沿线植被与水文地貌测绘用新型传感器及机载遥感技术（mDRONES4rivers）。 项目实施周期为2019-2022年，研究团队在德国境内莱茵河与奥得河沿岸的多个监测站点完成了数据采集。本项目产出的全部公开数据均可通过关键词“mDRONES4rivers”检索获取。 本数据集提供了德国莱茵河沿岸项目站点“Nonnenwerth”（中心坐标[世界大地测量系统1984（WGS84）]：50.637541°N，7.208834°E；面积：8公顷）的无人机系统（Unmanned Aircraft System, UAS）数据及元数据，支持下载，具体包括： • 多光谱正射影像（GeoTiff格式；包含6个波段：蓝（B）、绿（G）、红（R）、红边（Red-Edge）、近红外（NIR）、标记（Flag）；搭载相机：Micasense；分辨率：25厘米；缩写：MS_RAW） • RGB正射影像（GeoTiff格式；包含3个波段：R、G、B；搭载相机：Phantom；分辨率：25厘米；缩写：PH_ORTHO） • 数字表面模型（GeoTiff格式；单波段；搭载相机：Phantom；分辨率约5厘米；缩写：PH_DEM） • 相关技术报告（PDF格式；涵盖数据采集及使用Agisoft Metashape进行处理的技术元数据，多光谱正射影像、RGB正射影像+数字表面模型各对应1份） 上述文件将根据数据采集日期按季节分至不同目录中打包下载，命名格式为：项目名_项目站点_采集平台_年份_批次编号_季节名称，例如：mDRONES4rivers_NW_UAV_2019_01_Winter.zip。为方便用户全面了解所有文件、获取通用背景信息及数据预览，info.zip压缩包中包含以下文件： • 上述数据的概览表与元数据（xlsx格式） • 总结文档（PDF格式；详细说明传感器与数据采集流程，多光谱正射影像、RGB正射影像+数字表面模型各对应1份） 注：本数据集的处理以光谱信息提取为核心，并非用于大地测量目的，未对地理配准精度开展详细核查。
