Abstract: This paper describes an experiment for a proposed scheme using on-board satellite data to perform three-dimensional positioning for a pair of SPOT stereostrips. Based on the sampling geometry of French SPOT satellite images, ...

Abstract: Due to its high spatial resolution, IKONOS imagery has the highest potential for large-scale topographic mapping of the resource satellites currently available. The orthorectification of IKONOS images thus becomes an ...

Abstract: In this paper we discuss a semiautomatic measuring system that can extract images of cracks in the surface of concrete from multitemporal images. An accuracy assessment and analysis of the relationship between expansion ...
