The present invention provides a map error information obtaining system which can promote the collection of the map error information as well as reduce the number of man-hours required for researching the site and verifying whether or not the collected map error information is accurate. The map error information obtaining system herein disclosed comprises a position detecting apparatus including image obtaining means for obtaining image data indicative of an actual condition of and in the vicinity of a current position, and a center apparatus, the position detecting apparatus being operative to transmit map error information including a position of the map information and image data where it is judged that there is a difference, to the center apparatus. The center apparatus is operative to correct the map information after verifying whether or not the difference in the map information is accurate using the image data. Furthermore, the center apparatus is operative to calculate an evaluation point for each of the position detecting apparatuses which have transmitted the map error information so that operators operating the position detecting apparatuses can be rewarded in accordance with their evaluation points.

A polygon rendering device carries out a polygon division process for generating, based on polygon data which specifies a polygon to be rendered, a plurality of partial polygon data each specifying one piece of partial polygons which are obtained by dividing the polygon. Then, a rendering process is performed based on the generated partial polygon data so as to generate image data which represents an image of the polygon. Here, each of the partial polygons includes a plurality of triangles which respectively include a vertex of the polygon, and each of the triangles included in each of the partial polygons shares at least one edge with at least one other triangle included in the same partial polygon. In such a manner, the polygon rendering device can render polygons at high speeds.

This invention relates to map displaying system, in which the reference altitude value determining means obtains a reference altitude value in accordance with the altitude data in the specific area, and the altitude data changing means performs the processing that each altitude both in the plane area and the solid area have the continuity from one area to another. And the 2-dimensional road data storage means stores the 2-dimensional ground road data and the 2-dimensional underground road data separately. Therefore, the 3-dimensional road data preparing means prepares the 3-dimensional ground road data in accordance with the 2-dimensioanl ground road data and the altitude data, while preparing the 3-dimensional underground road data in accordance with the 2-dimensional underground road data and the altitude data.
