THE RELATION BETWEEN THE VALUES OF LAND SURFACE TEMPERATURE (LST), LAND USE AND COVER AND THE TOPOGRAPHY IN THE CITY OF MINAÇU-GO (2001)

Abstract

Alterations of imprint environment initiated for changes in land use and cover, as the condition of land surface temperature (LST), are relevant, considered your influence in hydrology system, terrestrial and atmospheric. The present study utilize the remote sensing for evaluate of more systematic form the relation between the land use and cover in spatial variation of land surface temperature, mainly in consonance with other element essential in characterization of thermal field, the topography. For execution of present work, leaded of elaboration of maps of land use and cover, Hipsométrico and the Land surface temperature, countersign establish the interlacement between then and measure the relation between this classes. The cartographic products demonstrate what has one direct and inverse relation between such natural covers and TST. The hipsometria, in general, also showed direct and inverse relation with surface temperature, with the bigger rate altimétrico register the smaller values of temperature and the bigger values partner the topographic valley. Key-words: Land surface temperature (LST), Land use, Hipsometria, Minaçu (GO), Remote Sensing.
