Digital Orthophotos and water-land-boundaries at the Elbe estuary (Germany), July 2022, Sat-Land-Fluss-project

In July 2022 we mapped the tidal area of the Elbe near Cuxhaven and Brunsbüttel. The data was gathered by UAV (Unmanned Aerial Vehicle) with a RBG camera and a PDGNSS-Rover (Precice Differential Global Navigation Satellite System) in three areas: 1) Otterndorf at low tidal level (beach area), 2) Neufelderkoog at low tidal level (wadden area), 3) Neufeld at high tidal level (flooded reed area). For each area we provide a digital orthophoto and the correlation of the measurement timing to the local sea level. The measurements were obtained at the same time as the radar satellite Sentinel 1 crossed the area. The data is structured in three zip-archives corresponding to the study areas: 1) 20220712_Tnw_Otterndorf.zip: provides the time series data as comma-separated text files (CSV)  provides (a) a digital orthophoto at 1,5 cm resolution, (b) an overview jpg showing of the measurement times and the local sea level, (c) timing of the UAV-flightlines and (d) two PDGNSS measurement series collected simultaneously as csv. (downloadable as 10.4 GB zip archive),  2) 20220712_Tnw_NeufelderkoogPriel.zip: provides (a) a digital orthophoto at 2 cm resolution and (b) an overview jpg showing of the measurement times and the local sea level (downloadable as 6,3 GB zip archive),  3) 20220720_Thw_Neufeld.zip: provides (a) a digital orthophoto at 2 cm resolution and (b) an overview jpg showing of the measurement times and the local sea level (downloadable as 8,4 GB zip archive). The data is used in the frame of the project "satellite based water-land-boundary detection" (Sat-Land-Fluss), as validation for Sentinel-1 derived water-land determinations. Sat-Land-Fluss was a R&D project lasting from 2020-2024, funded by the German Federal Ministry for Digital and Transport in the 4th project call "National Copernicus Application" (50EW2015).

BodenBewegungsdienst Deutschland (BBD) 2019-2023 L3 East West

Die vielfältige Geologie Deutschlands sowie die sich hieraus ergebende Nutzung sind Ursachen für verschiedenste Bodenbewegungen, wie z.B. Bodenkompaktion, Erdrutsche, Grundwasserentnahme, Erdgasförderung, (Alt-)Bergbau- und Kavernenspeicherbetrieb. Die Produkte des BodenBewegungsdienst Deutschland (BBD) basieren auf SAR Daten der Copernicus Sentinel-1 Mission und einer Persistent Scatterer Interferometrie (PSI) Verarbeitung. Das BBD Portal enthält PSI Daten der gesamten Bundesrepublik Deutschland (ca. 360.000 km²). Die PSI Technologie ermöglicht präzise Messungen von Bewegungen der Erdoberfläche im mm Bereich. Die Messpunkte (Persistent Scatterer, PS) entsprechen bereits am Boden vorhandenen Objekten, wie z.B. Gebäuden, Infrastruktur oder natürlichen Objekten, wie Gesteinen und Schuttflächen. Jeder PS wird durch einen über mehrere Jahre gemittelten Geschwindigkeitswert (ausgedrückt in mm/Jahr) und eine Zeitreihe der Verschiebungen charakterisiert. Für jeden PS kann die Zeitreihe der Verschiebungen von der ersten Sentinel-1 Aufnahme bis zur letzten ausgewerteten Sentinel-1 Aufnahme eingesehen werden. Die bewegungszerlegten virtuellen PS werden nach der mittleren Geschwindigkeit in vertikaler Richtung, gemäß der folgenden Konvention im BBD Portal visualisiert: - die grüne Farbe entspricht den virtuellen PS, deren mittlere Geschwindigkeit sehr gering ist, zwischen -2,0 und +2,0 mm/Jahr, d.h. im Empfindlichkeitsbereich der PSI Technologie; - in den Farben von gelb bis rot werden diejenigen virtuellen PS mit negativer Bewegungsrate visualisiert, d.h. Bewegungen nach Westen; - mit den Farben von türkis bis blau werden diejenigen virtuellen PS mit positiver Bewegungsrate visualisiert, d.h. Bewegungen nach Osten. Die Präzision der dargestellten PSI Daten liegt in der Größenordnung von typischerweise +- 2 mm/Jahr für die mittlere Geschwindigkeit.

Sentinel-5P TROPOMI - Aerosol Single-Scattering Albedo (ASSA), Level 3 - Global

Aerosol single-scattering albedo (ASSA) as derived from TROPOMI observations. ASSA is a measure of how much light is scattered by aerosols compared to how much is absorbed. It is important for understanding the impact of aerosols on climate and radiative forcing. ASSA is unitless; a value of unity implies that extinction is completely due to scattering; conversely, a single-scattering albedo of zero implies that extinction is completely due to absorption. Daily ASSA observations are binned onto a regular latitude-longitude grid.

Sen2Europe (2018)

Das Bundesamt für Kartographie und Geodäsie (BKG) hat ein Verfahren zur bedarfsbezogenen Bereitstellung von Fernerkundungsdaten entwickelt. Für die fernerkundliche Produktion werden derzeit optische Satellitenbilddaten in der Bundesverwaltung bevorzugt eingesetzt. Hierfür ist das sogenannte Mosaik-Verfahren eine wichtige Methode. Das Verfahren wurde mit den von der EU finanzierten Sentinel-2- Daten der europäischen Erdbeobachtungsinitiative Copernicus aufgebaut und kann für jeden optischen Datensatz (inkl. Luftbilder) angewendet werden. Wir stellen mit dieser Methode einen Service zur Verfügung, über den sich optische Fernerkundungsdaten für jedes Gebiet auf der Erde fachlich und bedarfsorientiert aufbereiten lassen. Über den Dienst Web Map Service (WMS) Sen2Europe wird den Bedarfsträgern ermöglicht, vorprozessierte und aufbereitete Fernerkundungsinformationen aus dem Erdbeobachtungsprogramm Copernicus (Sentinel-2, L1C-L2A), für Europa, in bestehende eigene Fachverfahren mit einzubinden. Die Bilddaten des Jahres 2018 wurden jeweils zu einem Mosaik zusammengefügt, welches eine Bodenauflösung von 10m hat. Ein Komposit aus drei Bändern (Sentinel-2 Bänder: 2, 3, 4 (R, G, B)) sowie eine Information zu den Eingangsbilddaten werden angeboten. Die Bilddaten wurden einem radiometrischen Farbausgleichsverfahren unterzogen um ein einheitliches Erscheinungsbild zu erlangen. Für jedes Mosaik beträgt die Wolkenbedeckung über das gesamte Gebiet weniger als 3%. Über den Request-Parameter TIME kann hier gezielt ein spezifischer Jahresstand angezeigt werden (z.B. Time=2018) (ohne TIME-Parameter wird der neueste Stand angezeigt).
