Satellite Color Images, Vegetation Indices, and Metabolism Indices from Erfurt, 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年全德国全域的陆地卫星（Landsat）时序影像与矢量化分割数据集。该影像数据按照TK100分幅规则进行裁切（详细信息参见：1:10万比例尺地形图分幅规则（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）两个物候时段，同步提供对应时期的植被指数产品，包括归一化差分植被指数（NDVI，Normalized Difference Vegetation Index）与植被近红外反射率（NirV，Near-Infrared Reflectance of Vegetation）。此外，数据集还为每一年度提供由近似均一像素构成的矢量化分区数据。影像数据的光谱特性与上述分区的形态学特征均已作为矢量属性纳入数据集中（详细说明参见文档《"马赛克（1984–2023）"数据说明》）。本数据集附带一份命名为D-Mosaik_Sheet-Sections的矢量图层，用于展示所有分幅数据的覆盖范围与质量概况，详见本文档。……
