Abstract:
1. A digital map generating system, generating a target scalar map block according to primary geographical area information, the generating system comprising: a geographical information database, storing the primary geographical area information; an area information database, storing regional area information of respective regional areas corresponding to the primary geographical information; an area parameter database, storing extreme point values of each of the regional areas; a target area access module, selecting the regional area information of two of the regional areas to be a starting location and an end location for the target scalar map block; a comparator module, comparing the extreme point values of each of the regional areas with the extreme point values of the starting location and end location; an area-computing module, determining a rectangle size of said target scalar map block according to a result of the comparison; a map division module, generating said target scalar map block according to the rectangle size and a display scale to include the regional areas of the starting location and the end location; and a storage module, storing the target scalar map block.
