GENERATING A MULTI-LAYERED GEOGRAPHIC IMAGE AND THE USE THEREOF
First Claim
1. A method of creating a two-dimensional graphical multi-layered image from a three-dimensional model of a geographic area to enhance a navigation database, the method comprising:
- receiving three-dimensional graphical object data that represents a geographic area, the three-dimensional graphical object including representations of a path, a path marking on the path, and terrain surrounding the path;
rendering a two-dimensional graphical layer of the path by removing the path marking and the terrain, projecting the path in a two-dimensional space, and tracing boundaries of the path, wherein rendering the two-dimensional graphical layer of the path is based on a specific perspective view of the three-dimensional graphical object;
storing the two-dimensional graphical layer of the path as a first independent image layer;
rendering a two-dimensional graphical layer of the path marking by removing the terrain, projecting the path and the path marking in a two-dimensional space, and tracing boundaries of the path marking, wherein rendering the two-dimensional graphical layer of the path marking is based on the specific perspective view;
storing the two-dimensional graphical layer of the path marking as second independent image layer;
rendering a two-dimensional graphical layer of the terrain by projecting the path, the path marking, and the terrain in a two-dimensional space, and then tracing boundaries of the terrain, wherein rendering the two-dimensional graphical layer of the terrain is based on the specific perspective view;
storing the two-dimensional graphical layer of the terrain as a third independent image layer; and
adding the first image layer, the second image layer, and the third image layer together to generate the two-dimensional multi-layered image, the two-dimensional multi-layered image configured to be displayed.

Abstract
Systems, devices, features, and methods for generating and/or using a multi-layered image are disclosed. For example, a method of creating a multi-layered image from a three-dimensional model of a geographic area includes receiving three-dimensional graphical object data that represents a geographic area. The three-dimensional graphical object includes multiple geographic features. A first graphical layer of a first geographic feature of the three-dimensional graphical object is rendered as a first independent image layer. A second graphical layer of a second geographic feature of the three-dimensional graphical object is rendered as a second independent image layer. The first graphical layer and the second graphical layer are combined or overlaid to form the multi-layered image. Also, removal of layers may occur in a reverse order of their creation and/or may avoid causing gaps within the other layers not removed.
