Multi-temporal and multi-angular analysis of very high spatial resolution images

Despite the fact that commercial optical very high spatial resolution satellite imagery has been available for more than 10 years, very little research has been done to take advantage of its multi-temporal and multi-angular information. In this paper, the benefits of using surface reflectance for the analysis of multi-temporal and multi-angular images are discussed using a 23 image time-series acquired between 2002 and 2010 by QuickBird and WorldView-2 over the city of Denver, Colorado. Results show that it is possible to extract useful information from multi-angular data regarding the structure of specific objects.
