GIS-based Hotspot and Cold Spot Localization in Solutions

Abstract

Abstract-Air temperature is for a long time one of meteorological variables that are in interesting continuously monitored by general and professional public. Especially urban climate is characterized by very strong temporal and spatial variability. This difference is primarily related to the specific areas in the city, such as industrial sites, parks, lakes, roads, squares or dense areas. Due to the uneven distribution of these elements is possible that a combination of several elements can accumulate negative impacts of extreme phenomenon, which may have an strong impact on society living in the city.Most studies of city climate often describe only urban heat island and spatial variability of air temperature. In the city already exists hot spots and cold spots. The aim of this paper is determine the key factors that influence the creation and intensity of these phenomena in Olomouc. Using GIS tools (multi-criterial model) define areas inclinable to these phenomena and determine relationship between the observed elements. The analysis of these elements can lead to the possibility of such an early warning of inhabitants before the emergence of local dangerous meteorological phenomena (formation of black ice, fog, poor air quality, high temperature, etc.) or to improve urban planning.
