13	TREE MITIGATION STRATEGIES TO REDUCE THE EFFECT OF URBAN HEAT ISLANDS IN CENTER TOWNSHIP, IN Rigg, Michelle C. 11 December 2012 (has links) Indiana University-Purdue University Indianapolis (IUPUI) / The purpose of this study was to identify urban heat island locations within Center Township, Indiana and to develop a model to determine areas of high social vulnerability. In addition, an urban heat island mitigation strategy was developed for socially vulnerable and highest temperature locations. Land surface temperature was estimated using Landsat ETM+ satellite imagery. Social vulnerability was estimated using principal components analysis and spatial analysis methods such as kernel density functions. These methods incorporate various socioeconomic variables, land surface temperature, and tree canopy cover. Tree canopy cover was extracted using Quickbird imagery among other techniques. Areas with high social vulnerability, high temperature and low tree canopy cover were analyzed and plantable spaces were assessed. The findings of this study will be shared with Keep Indianapolis Beautiful, Inc. so that they can inform their tree planting campaigns that seek to reduce the effects of urban heat islands on socially vulnerable populations.
