Intensive development of South Yakutia, a mountainous area in the Russian sporadic permafrost zone, must be founded on Ski de fond - Femme - Sous-vetements - Synthetique knowledge about regional permafrost conditions.New permafrost maps for mountainous areas in South Yakutia (the Elkon Mountains and the Olekma-Chara Upland) are presented that provide a more detailed and updated description of permafrost distribution in the area than those that were hitherto available.These maps are based on the previously-developed and tested method of detecting permafrost and unfrozen ground using Landsat-5/TM satellite data with relatively high resolution.The method represents Womens Pants a scheme for permafrost identification based on a set of landscape indicators: terrain elevation, slope angle and exposition, vegetation, snow cover, and land surface temperature (LST).
A correlation analysis of satellite data to full-scale field data has been carried out for the two areas under consideration.Indicator properties of LST obtained by Landsat-5/TM Band 6 Infrared have been characterized in detail for detection and regional mapping of permafrost.The effect of landscape factors (landscape cryo-indicators) on ground temperature and condition, frozen or unfrozen reflected in LST intensity, is demonstrated.
