Satellite Color Images, Vegetation Indices, and Metabolism Indices from Heidelberg, 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. […]“德国马赛克（Germany Mosaic）”是一套覆盖1984年至2023年德国全境的陆地卫星（Landsat）时序影像与矢量化分割结果数据集。影像数据按照TK100分幅进行划分（详细说明参见：Blattschnitt der Topographischen Karte 1:100 000，即1:10万比例尺地形图分幅）。该数据集为每一年份提供优化后的6波段影像，对应夏季（5月至7月）与秋季（8月至10月）两个观测时段，同时包含同期的植被指数，如归一化差分植被指数（NDVI, Normalized Difference Vegetation Index）以及植被近红外反射率（NirV, Near-Infrared Reflectance of Vegetation）。此外，数据集还为每一年份提供近似同质像素的矢量化“区域”。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收录（详见文档：《Mosaic (1984–2023) - Data Description》）。本文档中名为"D-Mosaik_Sheet-Sections"的矢量化图层，可用于概览所有分幅的覆盖范围与质量情况。[…]
