| Abstract: | Firstly, the paper introduces the theory of remote sensing image multinomial geometric rectifying, presents an idea of applying Longest Distance Method (LDM) to filter Ground Control Points (GCP) from overfull ones in a remote sensing image. Then, the paper recounts the theory of LDM and the flow of it and gives an example of how to apply this method. Lastly, it shows this method applied in practice. Practices prove that applying LDM to filter GCP is to raise the precision of geometric rectifying effectively. |
