Problems of remote sensing data use are considered for study of thermokarst proccesses dynamics in
territory of West-Siberian permafrost. Collection of nonsimulteneous space images Lansat, Meteor-3M
and ERS-2 is formed for period from 1973 to 2007 yrs. Dependence of relative changes of summarized
area of thermokarst lakes on latitude of test territories location is studied. It is shown that thermokarst
lakes areas on average increase in continuous permafrost and on average decrease in discontinuous
permafrost.
