Satellite Color Images, Vegetation Indices, and Metabolism Indices from Regensburg, Germany from 1984 – 2023@en

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. […]德国镶嵌数据集（Germany Mosaic）是一套覆盖德国全域、时间跨度为1984至2023年的Landsat卫星影像时序数据与矢量化分割单元。影像数据按照TK100分幅图幅（TK100 sheet sections）进行划分，详细信息可参见1:10万地形图分幅（Blattschnitt der Topographischen Karte 1:100 000）。本数据集为每年提供优化后的6波段影像，涵盖夏季（5月至7月）与秋季（8月至10月）两个时段，并同步提供同期的植被指数数据，包括归一化差分植被指数（Normalized Difference Vegetation Index，简称NDVI）与植被近红外反射率（Near-Infrared Reflectance of Vegetation，简称NirV）。此外，数据集还提供每年的近似同质像元矢量化分区数据。影像数据的光谱特性与上述分区的形态学特征均以矢量化属性的形式纳入其中，详细信息可查阅文档《Mosaic (1984–2023) - Data Description》。本文件中还提供了名为D-Mosaik_Sheet-Sections的矢量化图层，用于展示所有分幅图幅的覆盖范围与质量概况。[…]
