Change detection in urban areas with QuickBird imagery and Neural Networks algorithms F. Del Frate, G. Schiavon, C. Solimini
In this paper we report on some results obtained by applying the high resolution imagery of QuickBird for the analysis of the selected urban test area: the Tor Vergata University campus, located in Italy, South-East of Rome, whose extention is of about 600 ha. Initially, a pixel-based classification algorithm based on neural networks has been implemented to automatically discriminate between some identified type of surfaces, in particular bare soils, vegetated areas, buildings and asphalted surfaces. Change detection maps have been successively produced by applying the classification procedure to two different images taken at different dates.
