Satellite Color Images, Vegetation Indices, and Metabolism Indices from Bremen, Germany from 1984 – 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）是一套涵盖1984年至2023年德国全境的Landsat卫星影像时序数据集与矢量化分割区块。影像数据按照TK100分幅规则进行裁切（详见：1:10万比例尺地形图分幅（Blattschnitt der Topographischen Karte 1:100 000））。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，同时同步提供对应时段的植被指数产品，包括归一化植被指数（NDVI, Normalized Difference Vegetation Index）以及植被近红外反射率（NirV, Near-Infrared Reflectance of Vegetation）。此外，数据集还提供各年份的近似同质像元矢量化“区域”数据。影像数据的光谱特性与上述区域的形态学特征均作为矢量化属性字段纳入数据集（详见文档《镶嵌图（1984–2023）-数据说明》（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，用于概览所有分幅区块的覆盖范围与数据质量。[…]
