ABSTRACT:
Disclosed is a method for extracting and rendering data from digital charting databases. The software method integrates and combines bathymetric/topographic data from several sources into a stream of three-dimensional data points, creating a triangle surface mesh, and dividing it into pieces along arbitrary lines to create regularly sized and shaped areas for efficient storing and rendering. The method works by forming an initial triangle mesh of the area and then refining the mesh by incrementally adding each point to the mesh, until a full mesh representation is achieved. The large single file is then broken down into discrete geographic regions, and the region data is converted into a standard file format for viewing and/or processing.
