Study of Energy Flux Model Using Geospatial Technology
Surface energy estimation has a significant and key role in urban environment, climate as well as in the surroundings. This research study goal was to analyse the Landsat series data in biophysical parameters for estimating land surface temperature and heat fluxes over the year 2003 and 2016 and realizing its effect on heat disturbance over the Hyderabad region. Result shows that during the year 2003 to 2016 there is rapid increase urban area which in turn has a direct impact on the land surface temperature and heat fluxes and which leads to a significant rise of 1.40°C has been observed. Classification of the LU/LC using remote sensing data is an accurate way of monitoring the special growth and distribution of the urban area. The analysis of the Normalised Difference Vegetation Cover (NDVI) is done and the increase of 17.53% of the urban area has been observed which major land covers change. Thus from the study it is observed the energy flux in the urban area has increased from 2003 to 2016 because of lack of vegetation cover it overall energy flux value increased to 46.80W/m2.
