Satellite Color Images, Vegetation Indices, and Metabolism Indices from Holzminden, Germany from 1986 – 2023

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. […]"德国镶嵌图"（Germany Mosaic）是一套覆盖1984年至2023年全德国的陆地卫星（Landsat）时序影像与矢量化分割数据集。影像数据按照TK100分幅进行裁切（详细说明参见：1:10万比例尺地形图分幅（Blattschnitt der Topographischen Karte 1:100 000））。该数据集为每个年度提供优化后的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，并同步提供同期的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）等植被指数产品。此外，数据集还提供各年度的近似均质像元矢量化"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已作为矢量化属性收录，详见文档《镶嵌图（1984–2023）数据说明》（Mosaic (1984–2023) - Data Description）。本文件中以名为"D-Mosaik_Sheet-Sections"的矢量图层提供了所有分幅数据的覆盖范围与质量概览。[…]
