Abstract:

In the process of vectorization, the “island”like map is inadequate to deal with vectorization of raster data, in particular for the relationship between adjacent “islands” of the situation. In this paper, a novel method of vectorization is put forward. This approach can better deal with the relationship with the adjacent “islands” of the situation. Finally, the experiments prove the effectiveness of the method of vectorization.

Key words: raster data, vector data, vectorization of raster data, spatial data
