Überblick

Die Forschungstätigkeiten in der Sektion Fernerkundung und Geoinformatik am GFZ umfassen verschiedene Bereiche. Zum einen werden Verfahren für die Informationsgewinnung aus großen, komplexen Datensätzen aus Fernerkundungs- und in-situ Sensoren, sowie aus Simulationsmodellen und Geoarchiven entwickelt. Dazu werden Methoden aus Data Mining/Machine Learning, visueller Datenexploration, Datenbanken und Big Data Technologien für die spezifischen geowissenschaftlichen Herausforderungen angepasst und weiterentwickelt. Einen weiteren Schwerpunkt bildet die wissenschaftliche Leitung der deutschen Hyperspektralmission EnMAP sowie die Definition von zukünftigen Satellitenmissionen. Hinzu kommt anwendungsorientierte Forschung zur Beobachtung bio- und geophysikalischer Parameter sowie Oberflächendeformationen mithilfe optischer und Radar-Fernerkundungssatelliten, welche für ein breites Spektrum wissenschaftlicher Anwendungsfelder von Interesse sind. Dazu zählen Bodendegradation, geologische Exploration, “Precision Farming”, die Vegetation in ihrer globalen Funktion, natürliche und anthropogene Gefahren sowie die Wechselwirkungen zwischen Landoberfläche und Atmosphäre.

Technology transfer

FERN.Lab (Remote sensing for sustainable resource use) initiated by Daniel Spengler, Julia Neelmeijer and Theres Küster will be funded by Helmholtz starting from 2020. It is intended to become a technology platform for developing and operationalizing practical transdisciplinary methods of using remote sensing data. The lab focuses on collecting geoinformation, especially from satellite data, to meet the specific requirements of companies, agencies, and NGOs.
Christian Mielke and Friederike Körting together with Martin Otto and Arndt Schwaiger founded the company rad. Data Spectral Analytics UG (haftungsbeschränkt). The company aims at the usage of remote sensing and imaging spectroscopy applications in the mining sector from multiple remote sensing platforms. This way innovative solutions are provided to the mining industry for a more cost effective and sustainable resource discovery and recovery.
