This dataset contains high-resolution (5 cm/pixel) orthomosaics and digital elevation models (DEMs) from unoccupied aerial vehicle (UAV) surveys of biogenic structures in the German Wadden Sea. Two Pacific oyster reefs (Kaiserbalje, Nordland) and one blue mussel bed (Nordstrand) were monitored between 2020 and 2022. The data, processed via structure from motion (SfM) and georeferenced, are provided as raster files (*.tiff), ready for GIS analysis. The Random Forest (RF) classification shapefiles support the mapping of biogenic structures. This dataset facilitates research on biogenic structure growth, sediment dynamics, and geomorphological processes in intertidal environments
Die zur Verfügung gestellten Punktwolken wurden als Datengrundlage im BMDV-Expertennetzwerk (Arbeitspaket 10 „Multitemporale Zustandserfassung, Modellentwicklung und Veränderungsanalyse von Verkehrsinfrastrukturbauwerken“ im Themenfeld 3) aufgenommen. Zur Messung wurden unterschiedliche Sensoren verwendet, u.a. ein terrestrischer Laserscanner, ein UAV, ein mobiler Laserscanner sowie ein Fächerecholot. Die Punktwolken der Sensoren wurden miteinander fusioniert, sodass man pro Messepoche eine Punktwolke erhält. Die Schleuse Koblenz wurde in insgesamt sechs Epochen gemessen. Die erste Messkampagne fand während der Schleusensperre im Juni 2023 statt, die Schleuse war zu diesem Zeitpunkt trockengelegt. Die weiteren Messungen erfolgten im Abstand von je 3 Monaten seit September 2023 jeweils während der turnusmäßigen Wartungssperren der WSV. An der Bahnbrücke wurden insgesamt vier Messepochen durchgeführt. Die ersten beiden Messkampagnen erfolgten im September und Dezember 2023 (vgl. Abschnitt 4.3), die dritte im Juli 2024, die letzte Epoche erfolgte im Oktober 2024. Alle Punktwolken liegen in einem bauwerksspezifischen, lokalen Koordinatensystem.
In der <b> Fernerkundung - Luftbilder</b> werden aus großer Höhe Bilder von der Erdoberfläche aufgenommen, die anschließend aufbereitet und als hochwertige Geodaten bereitgestellt werden. <br> Diese Aufnahmen unterstützen bei der Dokumentation von Veränderungen, der städtischen Planung und der Überwachung von Umweltentwicklungen. Sie können sowohl als Datengrundlage für KI-Trainingsdaten als auch zur direkten Betrachtung der urbanen Landschaft genutzt werden. <br><br>Unser Ziel ist es, diese bedeutsamen Daten nicht nur Fachleuten, sondern auch der Öffentlichkeit zugänglich zu machen – leicht verständlich und nutzerfreundlich. <br><br><i>"Wie hat sich Hamburg entwickelt?" -- "Wie sah das Grundstück früher aus?" -- "Wo blüht es im Sommer?"</i> <br> <b>→ Ein Blick in die Daten lohnt sich.</b><br><br> <u><i>Hinweis:</i></u> So vielfältig die Anwendungsbereiche sind, so vielfältig sind auch unsere Datensätze. Je nach Aufnahmesystem – ob <b>Drohne</b>, <b>Flugzeug</b> oder <b>Satellit</b> variieren die Bilder in ihrer Qualität und Detailtiefe. Diese Unterschiede zeigen sich etwa in der Bildauflösung (GSD), den Farbdarstellungen (spektrale Auflösung) und/oder der Aktualität der Daten (zeitliche Auflösung). Nähere Informationen sind aus den Metadaten der Datensätze zu entnehmen.<br>
This dataset contains unoccupied aerial vehicle (UAV)-based photogrammetric point clouds, orthophotos, UAV-borne laser scanning point clouds, and terrestrial laser scanning point clouds of three nature reserves of the Sandhausen inland dunes in Baden-Württemberg, Germany: Pflege Schönau, Pferdstrieb Süd, and Zugmantel-Bandholz. The three surveyed areas each have a size of about 10 ha. UAV-based photogrammetric data of the three sites were collected in February, September, and October 2021 with a ground sampling distance of 2.0 to 2.5 cm/px. UAV-borne laser scanning data were collected in August and September 2021 and resulting point clouds have pulse densities between 123 and 227 pts/m². Additionally, the site Zugmantel-Bandholz was surveyed with a terrestrial laser scanner in May 2022 using eight scan positions. GNSS measurements were recorded in-flight and/or taken on the ground and were tied into the SAPOS reference network (RTK/PPK) to georeference the data. This dataset captures the current state of the inland dune in 2021 and 2022, in particular the topography and vegetation cover in different seasons of the year.
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 und JB Hyperspectral Devices.
