mDRONES4rivers-project: UAV-imagery of the project area Laubenheim 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 und JB Hyperspectral Devices. <br> 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‘. <br> In this dataset, the following UAS data and metadata of the project site ‘Laubenheim’ (center coordinates [WGS84]: 49.960007°N, 8.331229°E; area: 11 ha) at the Rhine River in Germany is available for download:<br> • Multispectral orthophotos (GeoTiff; 6 bands: B, G, R, Red-Edge, NIR, Flag; camera: Micasense; resolution: 25 cm; abbreviation: MS_RAW)<br> • RGB-orthophotos (GeoTiff; 3 bands: R, G, B; camera: Phantom; resolution: 25 cm; abbreviation: PH_ORTHO)<br> • Digital Surface Models (GeoTiff; 1 band; camera: Phantom; resolution: ca. 5 cm; abbreviation: PH_DEM)<br> • 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)<br> 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: <br> • Overview table and metadata of the above-mentioned data (xlsx)<br> • Summary (PDF, Detailed description of sensors and data acquisition procedure, 1x for multispectral orthophotos, 1x for RGB-orthophotos + digital surface models)<br> Note: the data was processed with focus on spectral information and not for geodetic purposes. Georeferencing accuracy has not been checked in detail.本数据集通过搭载于无人机（Unmanned Aerial Vehicle, UAV）及自转旋翼机平台的多光谱传感器采集，具备高时空分辨率，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）以及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，数据采集于德国境内莱茵河与奥得河沿线的多个测点。本项目产出的全部公开数据可通过检索关键词“mDRONES4rivers”获取。 本数据集提供德国莱茵河沿岸项目测点“劳本海姆（Laubenheim）”（中心坐标[WGS84]：49.960007°N，8.331229°E；面积：11公顷）的以下无人机系统（Unmanned Aircraft System, UAS）数据与元数据（Metadata），支持下载： • 多光谱正射影像（GeoTiff格式；6个波段：蓝、绿、红、红边、近红外（Near-Infrared, NIR）、标记波段；相机型号：Micasense；分辨率：25厘米；缩写：MS_RAW） • RGB正射影像（GeoTiff格式；3个波段：红、绿、蓝；相机型号：Phantom；分辨率：25厘米；缩写：PH_ORTHO） • 数字表面模型（Digital Surface Model, DSM；GeoTiff格式；1个波段；相机型号：Phantom；分辨率约5厘米；缩写：PH_DEM） • 配套技术报告（PDF格式；包含数据采集相关技术元数据，以及使用Agisoft Metashape进行数据处理的说明；多光谱正射影像配套1份，RGB正射影像+数字表面模型配套1份） 上述文件将按照数据采集日期所属季节分目录打包为数据集供下载（示例：mDRONES4rivers_NW_UAV_2019_01_Winter.zip = 项目名_测点名_平台_年份_批次.季节名称.季节）。为便于用户了解全部文件概况、获取基础背景信息及数据预览，info.zip压缩包中包含以下文件： • 上述数据的总览表与元数据（xlsx格式） • 数据总结文档（PDF格式；详细说明传感器参数与数据采集流程，多光谱正射影像配套1份，RGB正射影像+数字表面模型配套1份） 注意：本数据集仅针对光谱信息进行处理，未服务于大地测量需求，地理配准精度未进行详细核验。
