利用LANDSAT TM卫星数据和地理信息系统软件绘制了得克萨斯州达拉斯部分地区的微型城市热岛图。利用LANDSAT子场景进行非监督分类，提取树木覆盖信息，并与TM波段6数据（热）融合，绘制微型城市热岛和森林覆盖区的位置图。结果表明，微型城市热岛的存在是由于新开发的住宅区、停车场、商业区、公寓楼、和购物中心。所有微型城市的热岛都是辐射性的，中心温度最高。
LANDSAT TM satellite data and GIS software were used to map micro-urban heat islands in a portion of Dallas, Texas. Unsupervised classification were performed on a LANDSAT subscene to extract tree cover information which was merged with TM band 6 data (thermal) to make a map showing the location of micro-urban heat islands and wooded areas.Results indicate the presence of micro-urban heat islands are resulting from the lack of tree cover related to newly developed residential neighborhoods, parking lots, business districts, apartment complexes, and shopping centers. All micro-urban heat islands were radiative in nature, with highest temperatures in the center.
