Abstract
Earlier works have analyzed the urban heat island structure from thermal infra‐red images; however, the analysis was affected by rooftops which added a component of temperature above ground level. To allow the study of ground level data alone, the roof tops of buildings had to be removed from the image. An image processing technique was developed for removing the roof tops from the image. This technique is presented here with the results which are estimated to be between 81 % and 92% accurate.
