Research on DEM Modification and Production of Three-dimensional Images in the Intersection Region of Seawater and Land
The phenomena often appears that sea surface is above land,island is under sea surface and distortion of building inter-island in conflux area of water and land when creating three-dimensional image using fusing DEM and image.The paper introduced a fast method of modifying DEM and creating three-dimensional image in the batch by using PCI software.This method was validated by using SPOT5 and DEM in the Zhoushan area.The results showed that PCI could accurately mask the target objects and modify DEM in the batch; the result could be showed in three-dimensional mode by setting many parameters and mcct different requirements;the results could fly by setting given route; the file was organized in a systemic mode,which will facilitate management.
