Space monitoring of urban areas is based on research which uses satellite data, spatialtemporal changes of landscape and functional structure of the city and in selected indicators of the environment that are influenced by urbanization. In this paper on example of certain areas of the Kyiv metropolitan area the application of methodological issues are considered in the analysis of cosmic material changes in the landscape and the functional structure of Kyiv are associated with intense development in the valley of the Dnieper river and within the historical part. The analysis was carried out in two ways: 1) analysis of changes in the landscape and the functional structure of the city according to multispectral space imagery; 2) analysis of the distribution of surface temperatures in the historic part of the city by outer thermal scanner range The basis of the research methodology laid in our Centre processing technology space materials based on the use of so-called spectral indices and image classification with previous studies and the calculation of the underlying surface temperature according to the thermal range (10.40-12.5 microns) Landsat TM, ETM with an estimation the coefficient of a thermal radiation on normalized vegetation index (NDVI). Analysis of calculation results of temperature fields and mapping was performed using GIS. The obtained data indicates that the use of satellite data in monitoring urban landscapes can quickly track the changes of landscape and the functional structure of urban areas, identify dangerous trends in their development and monitor violations of environmental laws that can result in optimal management decisions in environmental and urban planning. Monitoring of the thermal field within the historical part of Kyiv shows that a decrease of natural land cover and sealing with urban areas increased surface heating in that area. As local microclimatic conditions, this can cause violation within protected areas and promote climate change at the regional level. The latest refers to the growth of the "urban heat island" problem, which is given very close attention in almost all developed countries. Thus, protection of vegetation and increasing its range in the historical part of Kyiv is in a priority to preserve ancient architectural ensembles. In addition, in our opinion, it is necessary to introduce the European countries experience for the construction buildings with "green roofs" that reduce the negative impact of high temperature in an urban environment in summer and reduce heat and energy losses in the winter
