Abstract: |
There are some problems in a traditional Digital Map such as annotation information lost , overlap among annotations .This paper proposes a new algorithm for point, line and polyon elements .It divides the screen into many raster grids, labels of points, lines and polygons are organically unified so that each note is not covered by each other. The algorithm is of good simplicity, efficiency. It is successfully applied in the vehicle navigation system, and the label configuration is reasonable without any overlap.
