<p>Urban heat island has become a serious environment problem in nowadays. One of the reasons is the buildings block the wind blow. For planning a scientific urban geometry to reduce the influence of urban heat island, one of the solutions is finding the free wind paths. There many previous works based on GIS, this paper will offer a new method found on image processing in digital map. Using MATLAB instead of GIS device, the algorithm provides a simple and easy-using way to detect the free wind paths in the eight directions.</p>
