Ortho-rectification of QuickBird imagery with OSSIM (Open Source Software Image Map)

QuickBird imagery is increasingly used in different areas of land-related planning activities. However, by delivery the images are normally not ortho-rectified which means that, due to distortions, they cannot be used for mapping or spatial analysis, particularly if the image area covers mountaneous terrain.
Ortho-rectification is supposed to correct for the image distortions that are caused mainly by hilly terrain, but also by systemic deviations that occur during image-capturing at the sensor.
This tutorial leads through the ortho-rectification of QuickBird Standard ortho-ready satellite imagery, using an Open Source approach with OSSIM.
