ORTHORECTIFICATION OF QUICKBIRD BASIC AND STANDARD ORTHOREADY DATA

For a proper exploitation of satellite data, geometrical processing is a key issue. Several techniques can be applied for this purpose. DigitalGlobe, which operates the QuickBird satellite, within its products integrates the image data with additional information that can be handled by image processing software packages for a proper orthorectification of the data. In this paper, focus is on the geometrical processing of the Basic and Standard OrthoReady QuickBird products using commercial image processing software. For a set of four frames, both products were collected and processed with the same sets of Control and Check Points by applying the RPC approach (for both products) and the rigorous approach (for the Basic imagery). The results show that better accuracy can be obtained with Basic images, and that the rigorous approach supplies slightly better results compared to the RPC-based processing.
