Abstract

Commercial high-resolution satellite imaging sensors are used for precision mapping, analysis and earth science applications. The evaluation of their imaging performance on-orbit requires special ground targets. Urban areas are rich with potential image quality targets with simple geometries, scuh as points, lines and edges. In this paper, we use parking lot stripes to evaluate the Line Spread Function (LSF) of the DigitalGlobe QuickBird sensor and compare the results to those obtained from edge targets. The two techniques produce equivalent LSF measurements. Parking lot stripes are therefore an alternative target that have some advantages and disadvantages compared to edges.
