Metric quality evaluation of satellite high resolution images in urban areas

The recent acquisition of high resolution satellite images leads one to consider and evaluate their potential metric accuracy in order to point out if they can successfully be used for photogrammetric applications. This study shows some results referred to the planimetric accuracy obtained by orthocorrection of IKONOS 2 panchromatic images acquired on urban areas. The procedures have been carried on using the OrthoEngine7 satellite module available within the software PCI.
