Abstract

This paper presents a method for solving main problems in the multi-source data integration of land and sea including the inconsistent horizontal and vertical datum, the differences of data model and format and the discrepancy of a geographical feature derived from different data source,. Firstly, based on the transformation of horizontal coordinate and calibration of vertical datum, spatial data are reconciled. Secondly, DEM of digital coastal zone are established by the combination of topographic and bathymetric data from sampled soundings and simplified contours. Finally, the visualization and multi-scale representation of the DEM is realized. Experimental results demonstrate that the proposed method could seamlessly integrate multi-source land and sea data.
