Abstract: A computer-implemented method for converting a raster image map to a vector image map includes receiving an electronic raster image that shows an indoor map of a building structure. The method also includes determining whether the indoor map is a line map. If not, the indoor map is converted into a line map. Next, the electronic raster image is processed to generate a processed raster image of the indoor map. The method then extracts vector lines from the processed raster image to generate an electronic vector image that includes the indoor map of the building structure.
