Abstract :
WorldView-2 has 8 multispectral bands and 1 pan band. In its LIB level data files, these bands have the same camera model and orientation model. But based on the study of moving objects´ characteristics in images from different bands, we found that, like the situation for QuickBird 2 sensor, different band has different imaging time. This paper introduced the calculation method for the imaging time difference of different bands of WorldView-2, reasoned out a possible CCD detector´ layout of the focal plane, and pointed out some drawbacks of the current LIB level data of WorldView-2. Secondly, this paper introduced some potential usage for the imaging time difference of different bands of WorldView-2, including ground traffic animation, ground traffic data collection.
