mDRONES4rivers-project: UAV-imagery of the project area Reitwein at the River Oder, 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 ‘Reitwein’ (center coordinates [WGS84]: 52.500961°N, 14.629186 °E; area: 60 ha) at the River Oder 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 and flight altitude, as the data was collected here from two different flight altitudes (e.g. mDRONES4rivers_RW_UAV_2020_03_summer_70m.zip = projectname_projectsite_platform_year_no.season_name.season_flightaltitude.zip). 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.本数据集采用搭载于无人机（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，服务于分类任务。本工作隶属于研发项目“德国联邦水道沿线植被与水形态测绘用新型传感器及机载遥感技术”（mDRONES4rivers），合作单位包括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。 项目执行周期为2019-2022年，数据采集于德国境内莱茵河与奥得河沿线的多个监测点位。本项目产出的所有公开数据集均可通过搜索关键词“mDRONES4rivers”获取。 本数据集提供德国奥得河沿岸“Reitwein”项目点位（中心坐标[WGS84]：52.500961°N，14.629186°E；面积：60公顷）的以下无人机系统（Unmanned Aircraft System, UAS）数据与元数据供下载： • 多光谱正射影像（GeoTiff格式；包含6个波段：蓝、绿、红、红边、近红外（Near-Infrared, NIR）、标记波段；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：红、绿、蓝；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） • 配套技术报告（PDF格式；包含数据采集及Agisoft Metashape处理流程相关的技术元数据；多光谱正射影像对应1份，RGB正射影像+数字表面模型对应1份） 上述文件将按照数据采集日期与飞行高度分季存储为单目录数据集以供下载，本数据集采集自两种不同飞行高度（示例文件名格式：mDRONES4rivers_RW_UAV_2020_03_summer_70m.zip = 项目名_项目点位_平台_年份_序号_季节名称_飞行高度.zip）。 为提供所有文件的概览、通用背景信息及数据预览，以下文件存储于info.zip压缩包内： • 上述数据的概览表与元数据（XLSX格式） • 数据汇总说明（PDF格式；包含传感器与数据采集流程的详细说明；多光谱正射影像对应1份，RGB正射影像+数字表面模型对应1份） 注意：本数据集仅针对光谱信息开展处理，未用于大地测量目的，且未对地理配准精度进行详细核查。
