In this work, a practical application of digital image processing techniques using satellite images, with the purpose of identification of changes in the metropolitan area of Valencia, and its 3D representation by the integration of high resolution images and a DEM, is presented. Some procedures for automatic change detection are described, including the radiometric and geometric correction of the images. As a result of this, a map of changes of the urban areas is obtained. Then, the orthorectification method and the enhancement of a high resolution image (QuickBird) are described, as well as the fusion of panchromatic and multispectral images. Finally, a 3D virtual flight has been generated, incorporating the most relevant changes in the urban area of Valencia, being related to the correspondent GIS database.Downloads
