Library of spectral characteristics of vegetation in Turkmenistan

The article describes the mechanism of creating a spectral library of natural objects that make up the main vegetation cover of the Karakum Desert. The concept of creating a spectral library of vegetation is formulated. A pilot version of the spectral library of vegetation of Turkmenistan (26 types of pasture vegetation of Turkmenistan) is presented. Research work was carried out in the eastern regions of the country, in the Central Karakum Desert and in the vicinity of the Caspian lowland. In hyperspectral decoding of satellite images, the functional significance of spectral libraries is to determine the type, geographical location and distribution of vegetation across the spectrum. The library contains packages of characteristics for each type, including: description of the object, data from spectrometric measurement in the form of graphs, geographical coordinates, and a photograph of the sample. The spectral library of vegetation of Turkmenistan can be used for systematic monitoring of the state of vegetation cover, obtaining operational information on the direction and scale of changes occurring in them, monitoring the environment, mapping vegetation, and developing methods for remote sensing of the Earth.
