THIS - Tool for Heat Island Simulation: A GIS extension model to calculate urban heat island intensity based on urban geometry
This paper presents a simulation model, which was incorporated into a Geographic Information System (GIS), in order to calculate the maximum intensity of urban heat islands based on urban geometry data. The methodology of this study stands on a theoretical-numerical basis (Oke’s model), followed by the study and selection of existing GIS tools, the design of the calculation model, the incorpora...
متن کاملUrban Heat Island
We are all familiar with the fact that cities are generally warmer than the surrounding, more rural areas. We see it referenced most nights in our television weather reports. It is especially significant on nights with clear skies and light winds which favor radiational cooling. This is most significant in the rural areas but in the city, the excess heat absorbed during the day and the local he...

متن کاملRule Based Classification for Urban Heat Island Mapping
SUMMARY One of the main parameter for urban heat island mapping is the land cover information. Satellite data were used to map the land cover over the study area, CyberJaya. Remotely sensed data were processed using pixel based and object based image processing techniques. Most traditional classification approaches are based exclusively on the digital number of the pixel itself. Thereby only th...
