Extraction and Rendering Techniques for Digital Charting Databases

Abstract

This patent application discloses 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 triangular surface mesh, and then divides 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 triangular 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 regional data is converted into a standard file format for viewing and/or processing.
