Abstract
Multi-spectral and multi-temporal satellite imagery provide the most reliable technique of monitoring of different urban structures regarding the net radiation and heat fluxes associated with urbanization at the regional scale. Investigation of radiation properties, energy balance and heat fluxes is based on satellite data from various satellite sensors and in-situ monitoring data, linked to numerical models and quantitative biophysical information extracted from spatially distributed NDVI-data and net radiation. Based on Landsat TM, Landsat ETM and IKONOS satellite images were classified for Bucharest, Romania, urban land use/cover and analyzed surface biophysical parameters like urban surface temperature and NDVI for 1984 - 2005 period. Spatio-temporal changes of surface biophysical parameters were examined in association with landuse changes to illustrate how these parameters respond to rapid urban expansion in Bucharest and surrounding region. This study attempts to provide environmental awareness to urban planners in future urban development. The land cover information, properly classified, can provide a spatially and temporally explicit view of societal and environmental attributes and can be an important complement to in-situ measurements.
