WMS LGL-BW SAT Sentinel-2 2021 CIR 10 m

This service provides the Baden-Württemberg-Mosaike monthly produced in the digital@bw project “Competence Field Satellite Data” based on Sentinel-2 satellite data for the year 2021 in CIR (MSI Color-Infrared, Sentinelbands: 8/4/3) The so-called color infrared image consists of the Near Infrared (NIR)-, the Red-, and the Green Channel. From this representation, the state of vitality can be derived from vegetation. Healthy vegetation has a high return radiation in the infrared range and therefore appears bright red, while sick or dead vegetation is depicted in brown to grey tones. The mosaic calculation is under construction. Following completion, this service will be expanded by additional mosaic layers.本服务提供由digital@bw项目“能力领域卫星数据（Competence Field Satellite Data）”基于2021年哨兵-2（Sentinel-2）卫星数据制作的巴登-符腾堡州月度镶嵌图，采用CIR（MSI彩色红外，Sentinel波段：8/4/3）合成方式。该彩色红外影像由近红外（Near Infrared, NIR）、红光与绿光三个通道构成，通过此类影像可反演植被的活力状态：健康植被在红外波段具有较高的反射辐射，因此呈现亮红色调；而受病害或枯死的植被则呈现棕至灰色的色调。 当前该镶嵌图的计算工作仍在进行中。待项目完成后，本服务将新增更多镶嵌图层以拓展服务内容。
