USING MULTISPECTRAL SENTINEL-2 DATA TO MONITORE SUBMERSE MACROPHYTES

摘要

Due to climate change and the involved temperatures ofrnBavarian freshwater lakes, the invasive submersernmacrophytes Elodea nuttallii and Najas marina exhibitrna massive expansion. To map these processes, arnmonitoring system based on remote sensing methods isrnunder development. The main part of the monitoringrnsystem is a coupled reflection-/growth-model, whichrnderives biometrical parameters for the EU waterrnframework directive (WFD) by inversion of thernreflectance spectra. For operational monitoring tasks arnhigh revisiting time is necessary. Hence, the Sentinel-2rnsensor might be very promising, as filling the gaprnbetween RapidEye and WorldView2 and betweenrnhyperspectral an aerial images. This paper outlinesrnprinciples, methods and first results of the project.
