Geometric Correction and Spatial Visualization of Accuracy on QuickBird Imagery

摘要

Since the successful launch of DigitalGlobe's QuickBird satellite on Oct 18th, 2001, QuickBird imagery has become the best choice for large-scaled mapping using high resolution satellite images. This paper first presents a quantitative evaluation of the geometric accuracy that can be achieved with QuickBird imagery using the metadata provided with DigitalGlobe's image products, then the technology of spatial visualization for the accuracy determination and the whole expression are put forward.
