Abstract： With the improvement of remote sensing image quality and the acceleration of update frequency， the computing ability of traditional slicing is limited. In order to meet the needs of fast image slicing， this paper draws lessons from the idea of parallel computing. A set of tile parallel slicing and image fast slicing algorithm based on tile merging are designed and implemented. Based on the experimental results， the slicing efficiency is improved obviously， which effectively solves the problem of low efficiency of stand-alone slicing.
