Textbook on Analysis of Urban Heat Island: Application of GIS and Remote Sensing Techniques

As a result of industrialization and urbanization, soft land cover on the earth surface is replaced with low reflective artificial materials. Surface temperature fluctuations are highly influence by these land cover changes. Onsite measuring of land surface temperature (LST) is a time consuming and a crucial task. Therefore, scientists suggest deriving land surface temperature by using remote sensing techniques. Satellite images are the key elements which are used to obtain LST as well as change detections of surface cover. Urban heat islands of a given area can be extracted according to the derived LST values. This book describes the methods that can be used to obtain LST values, heat island areas and preparation of thermal risk maps by using satellite images.
