Die Beurteilung und Stabilisierung der Dynamik von Landschaftsstrukturveränderungen in tropischen Regenwald-Randzonen erfordert aktuelle und flächendeckende Kartierungen der Landnutzungen als Grundlage von Planungen für zukünftige Maßnahmen. In dem Forschungsvorhaben sollen flächendeckend Landnutzungs- und Vegetationskarten über Randbereiche zu tropischen Regenwäldern mit Hilfe von satellitengetragenen Fernerkundungssensoren (SPOT-PAN + XS/XI oder LANDSAT-TM) hergestellt werden. Durch bestimmte digital durchgeführte Algorithmen sollen die Satellitenbilder zur Herstellung thematischer Karten klassifiziert werden. Die Ergebnisse der Klassifikation werden anhand von Kontrollflächen, für die ebenso wie für die Trainingsgebiete die Landnutzung bekannt sein muss, verifiziert. Der Prozess von Klassifikation und Verifikation ist iterativ und wird durch wiederholte Modifikation des Klassifikationsverfahrens solange fortgeführt, bis keine nennenswerte Steigerung der Klassifikationsgenauigkeit mehr erreichbar ist.
The "Germany Mosaic" is a time series of Landsat satellite images and vectorized segments covering the entirety of Germany from 1984 to 2023. The image data are divided into TK100 sheet sections (see further details: Blattschnitt der Topographischen Karte 1:100 000). The dataset provides optimized 6-band imagery for each year, representing summer (May to July) and autumn (August to October) seasons, along with vegetation indices such as NDVI (Normalized Difference Vegetation Index) and NirV (Near-Infrared Reflectance of Vegetation) for the same periods. Additionally, vectorized "zones" of approximately homogeneous pixels are available for each year. The spectral properties of the image data and the morphological characteristics of these zones are included as vector attributes (see Documentation: "Mosaic (1984–2023) - Data Description"). An overview of the coverage and quality of all sheet sections is provided as a vector layer titled D-Mosaik_Sheet-Sections within this document. The Germany Mosaic can also be considered a spatial-temporal Data Cube, enabling advanced analysis and integration into workflows requiring multi-dimensional data. This structure allows users to perform operations such as querying data across specific time periods, analyzing trends over decades, or aggregating spatial information to generate tailored insights for a wide range of research applications. In mid-latitudes, seasonal variations in vegetation—and consequently in the image data—are typically more pronounced than changes occurring over several years. The temporal segmentation of the dataset has been designed to encompass the entire vegetation period (May to October), with the division into summer and autumn periods capturing seasonal metabolic shifts in natural biotopes. This segmentation also records most agricultural changes, including sowing and harvesting activities. Depending on weather conditions, the individual image data represent either the median, mean value, or the best available image for the specified time period (see Documentation: "Mosaic (1984–2023) - Data Description). Remote sensing has become an indispensable tool for environmental research, particularly in landscape analysis. Beyond conventional applications, the Germany Mosaic supports the development of digital twins in environmental system research. By providing detailed spatial and temporal data, this dataset enables the modeling of virtual ecosystems, facilitating simulations, scenario testing, and predictive analyses for sustainable management. Moreover, the spatial and temporal trends captured by remotely sensed parameters complement traditional approaches in biological, ecological, geographical, and epidemiological research.

The aim of my study is to calibrate PAR from small lakes against tree biomass, which can be used to achieve quantitative estimates of biomass in the past. Furthermore, the relation between pollen percentages and plant abundance will also be investigated. As study area, the state Brandenburg was chosen, because it has a large number of lakes and is covered by different plant communities, like conifer forest, mixed forest, deciduous forest and open land. These are situated on a range of soil types in a terrain with little altitudinal differences. Lakes in different types of landscape were selected. They were of almost uniform size, mostly ranging from 100-300 m in diameter and without inflow and outflow. Deeper lakes in proportion to the lake size were preferred, to avoid lakes with a high pollen redeposition. In order to have an effective fieldwork and to get the broadest possible data spectrum for modeling, the relevant pollen source area of pollen (Sugita, 1994) was estimated, based on the map CORINE. The calculation shows that the pollen source area is approximately 5-6 km. However, we also sampled lakes which are situated closer together, especially when the landscape structure was very heterogenic at the small scale. From the surface samples of 50 lakes, the pollen percentages of different taxa will be compared with the information from the forest inventory data for different distances around the lakes to evaluate theoretical considerations of pollen source area. These data are available at the data base Datenspeicher Wald, which contains information about cover, age and biomass for the different tree species. This information was collected during the time of the German Democratic Republic (DDR) and is in the most continued. Concurrently, 15 of the short cores are selected for dating by 210Pb. PAR will be calculated based on the sedimentation rates obtained for these cores, so that PAR can be compared to tree biomass for different time slices over the past 50 years.
Titel: Braunkohlenplan als Sanierungsrahmenplan für den stillgelegtenTagebaubereich Borna-Ost/Bockwitz Planungsstand: verbindlicher Braunkohlenplan als Sanierungsrahmenplan seit 08.08.1998 Inhalt: * Die bergbauliche Sanierung ist weitestgehend abgeschlossen. Noch bestehende Handlungsschwerpunkte beschränken sich auf Voraussetzungen zur Vorbereitung von Folgenutzungen. * Im Zuge der Restlochflutung durch Eigenaufgehen (Grundwasserzufluss), d. h. ohne Einleitung von Flutungswasser aus dem aktiven Bergbau bzw. von Flussläufen, entsanden bis Ende 2005 der 1,7 km² große Bockwitzer See, der ca. 0,3 km² große Restsee Südkippe und der ca. 0,2 km² große Restsee Hauptwasserhaltung. Der ca. 0,1 km² große Restsee Feuchtbiotop entsteht durch Ansammlung von Oberflächenwasser in einer Geländesenke im Kippenmassiv. Der ca. 0,8 km² große, im Tagebaubereich Borna-Ost gelegene Harthsee war bereits Ende 1995 endgeflutet (Einleitung von Sümpfungswasser aus dem Tagebau Bockwitz bzw. Eigenflutung durch Grundwasserzufluss). Die Vorflutgestaltung schließt im Tagebaubereich Bockwitz den Verbund der Restseen mit Anbindung an die Eula und im Tagebaubereich Borna-Ost die Anbindung des Harthsees an den Harthbach zur Regulierung der Endwasserstände ein. * Die in den Kippenbereichen etablierte Landwirtschaft verfügt über einen Bestandsschutz (Anlage von Alleen und Flurgehölzen zur Landschaftsaufwertung). Prioritäre Handlungsfelder der Forstwirtschaft bestehen in der Waldmehrung (naturnahe, standort- und funktionsgerechte Aufforstungen vorrangig auf Kippenflächen) sowie im waldökologischen Umbau forstlicher Reinbestände (Kippenflächen Bereich Borna-Ost). * Für Natur und Landschaft bestehen durch das Vorhandensein differenzierter Landschaftsstrukturen (Trocken- und Feuchtstandorte, Steilböschungsbereiche und Abbruchkanten, Wasserflächen, Wald, Offenland) vielfältige Entwicklungsbedingungen. Bedeutsame Landschaftselemente bilden Fließ- und Stillgewässer (Bürschgraben, Schenkenteiche, Restsee Feuchtbiotop, Blauer See, Grüner See), naturnahe Areale und Sukzessionsbereiche (Restsee Hauptwasserhaltung, Restsee Südkippe, Südbereich des Bockwitzer Sees und des Harthsees, Bereich der ehemaligen Kompostieranlage, Kippenflächen Bereich Südkippe und Südbereich Bockwitzer See, Bereich Feuchtbiotop, ehemelige Innenkippenzufahrt) und markante Oberflächenformen (Lerchenberg, Ringwall, Ostböschung des Bockwitzer Sees). Im August 2003 wurden wesentliche Teile der entstandenen Bergbaufolgelandschaft als Naturschutzgebiete (NSG) ausgewiesen. * Freizeit und Erholung konzentrieren sich sowohl beim Bockwitzer See als auch beim Harthsee auf den Norduferbereich. Während am Harthsee bereits seit 1995 wassergebundene Erholungsnutzung (Badebetrieb) etabliert ist, bestehen am Bockwitzer See die Voraussetzungen dazu mit Erreichen der konzipierten Einstauhöhe von + 146 m NN (' Badestrand, Bootsanlegestelle). Es sollen Erholungsnutzungen eingeordnet werden, die den Charakter der Naturverbundenheit berücksichtigen. * Die Verkehrserschließung (Anschluss an B 176, K 7933) wird künftig durch die Ortsumgehung Borna der B 95 zwischen Zedtlitz und Kesselshain und die vorgesehene Trasse der A 72 deutlich verbessert. Damit werden neben der Verbesserung der regionalen Verkehrsinfrastruktur Voraussetzungen zur weiteren Erschließung der Bergbaufolgelandschaft geschaffen. Das Sanierungsgebiet wird durch ein Netz von Rad-, Wander- und Reitwegen sowie Aussichtspunkten erschlossen.
