Satellite Color Images, Vegetation Indices, and Metabolism Indices from Weiden, 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1984年至2023年覆盖全德国的Landsat卫星时序影像与矢量化分割区块数据集。该影像数据按照TK100分幅进行划分，详细信息参见：1:10万比例尺地形图分幅（Blattschnitt der Topographischen Karte 1:100 000）。数据集为每个年度提供优化后的6波段影像，覆盖夏季（5月至7月）与秋季（8月至10月）两个时段，并同步提供对应时段的植被指数，包括归一化差分植被指数（Normalized Difference Vegetation Index，NDVI）与植被近红外反射率（Near-Infrared Reflectance of Vegetation，NirV）。此外，数据集还提供各年度的近似同质像素矢量化“区块”。影像数据的光谱特性与这些区块的形态学特征均作为矢量化属性被纳入数据集，详细说明参见文档"Mosaic (1984–2023 - Data Description)"。本文件中提供了所有分幅的覆盖范围与质量情况的概览，以名为D-Mosaik_Sheet-Sections的矢量图层。[…]"
