资源简介:

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)"数据集涵盖1984年至2023年全德国范围的陆地卫星(Landsat)时序影像与矢量化分割区块。影像数据按照TK100分幅(即1:10万比例尺地形图分幅,详细信息参见:Blattschnitt der Topographischen Karte 1:100 000)进行划分。该数据集为每一年提供优化后的6波段影像,分别对应夏季(5月至7月)与秋季(8月至10月)两个时段,同时附带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同质像素矢量化“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字段收录(详细文档参见《“马赛克(1984–2023)-数据说明”》)。本文档中名为D-Mosaik_Sheet-Sections的矢量化图层,提供了所有分幅的覆盖范围与质量情况概览。[…]
