Joint remote sensing, synchronous ground based studies, combined with GIS technologies for estimation of the state of urban and agricultural lands provide a valuable source of information for management of urban green territories and agricultural activities on the field. They constitute a part of the data base used for operation of a number of models for evaluation and forecast of the state of urban territories and land (soil and vegetation) resources.
Based on satellite images studies, simple relations between the water and temperature regimes of soil and vegetation covers and their optic or thermal characteristics are sought. These studies have to be combined with GIS technologies for evaluation of spatial distribution of urban green territories and agricultural land management.
