Mobile Feldspektrometermessungen

Collected, processed mobile field spectroscopy measurementes, acquired during the campaigns within the frame of the mDRONES4RIVERS project in the years 2019, 2020 and 2021 respectively. Measurement were conducted in river-shore areas along the Rhine in Emmericher Ward, Nonnenwerth, Niederwerth, Kuehkopf and Laubenheim in Germany, to accompany airborne, multispectral mapping and to collect representative hyperspectral signatures of vegetation and sediments. The incoming radiance is measured with optics of hemispherical (~180°) field of view and the reflected radiance with conical (~25°) field of view, optics were stabilized with and active gimbal.

The data is present as human-readable .csv files and structured for each year in folders named with date and place of recording. Raw data, calibrated reflectance, reflected radiance, incoming radiance from measurements with the RoX field-spectrometer and derived vegetation indices (VI) are in subfolder /JB-112-GX/. Associated photos for each recorded footprint are collected in the /fotos/ folder. The derived level-2 data products are placed in /mD4R_L3-products/ and contains an overview table with unique ID, summarized meta-data including notes from the field protocol, associted photo-ID, GPS coordinates in WGS-84 and in ETRS 89 - 32N, classification information in 4 levels of differentiation and VI for each recorded footprint. In addition is the deconvolved multispectral reflectance response for the MicaSense Red Edge and Red Edge Blue, as well as the Gyrocopter costum sensor PanX 3.0 with all available filters reported with mean and standard deviation for each footprint in an individual file per sensor. Furthermore, this folder contains the mean and standard deviation of the hyperspectral reflectance as recorded by the RoX for each footprint. Primary key for all tables is the collumn IDMD4R, which contains a unique identifier for each footprint, composed out of the short for place of recording, year of recording, season (1 - winter, 2 - spring, 3- summer, 4 - fall), date, work group and running index. In addition, the protocol.txt file contains the raw notes taken during the field measurements. The same information is also present in the notes column of the overview table in the products folder.
