Satellite Color Images, Vegetation Indices, and Metabolism Indices from Darmstadt, Germany from 1985 – 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. […]"德国马赛克（Germany Mosaic）"是一套覆盖1984年至2023年全德国范围的陆地卫星（Landsat）时序影像与矢量化分割数据集。该影像数据按照TK100分幅规则进行切分（详见：Blattschnitt der Topographischen Karte 1:100 000）。本数据集为每一年度提供优化后的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，同时包含同期的归一化植被指数（NDVI, Normalized Difference Vegetation Index）与植被近红外反射率（NirV, Near-Infrared Reflectance of Vegetation）等植被指数产品。此外，数据集还为每一年度提供了近似同质像素的矢量化区域。影像数据的光谱特性与这些区域的形态学特征均已作为矢量化属性纳入其中（详见文档"Mosaic (1984–2023) - Data Description"）。本文件附带的命名为D-Mosaik_Sheet-Sections的矢量图层，可用于查看所有分幅的覆盖范围与质量概况。[…]
