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. […]

“德国镶嵌图数据集(Germany Mosaic)”是一套覆盖全德国、时间跨度为1984年至2023年的陆地卫星(Landsat)时序影像与矢量化分割单元集合。该影像数据按照TK100图幅进行分幅(详细信息参见:1:10万比例尺地形图分幅(Blattschnitt der Topographischen Karte 1:100 000))。本数据集为每年提供经过优化的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,数据集还提供每年的近似同质像元矢量化“区域”单元。影像数据的光谱特性与上述区域单元的形态学特征均以矢量化属性字段的形式提供(详见文档《1984–2023年镶嵌图数据集说明》(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,用于展示所有图幅的覆盖范围与质量概况。[…]
