Abstract:
A computer implemented method of preparing bit-mapped map images of a desired surface area, the method comprising:providing first and second bit-mapped map images; cropping a portion of the first bit-mapped map image to achieve a boundary having a straight line portion adapted to being fitted adjacent the second bit-mapped map image; cropping a portion of the second bit-mapped map image to achieve a boundary having a corresponding straight line portion adapted to match the straight line portion of the boundary of the first bit-mapped map image, wherein a desired feature of the second bit-mapped map image is aligned so as to merge with the corresponding feature of the first bit-mapped map image without visual discontinuity; and storing the cropped first and second bit-mapped map images for subsequent retrieval for display as a plurality of bit-mapped map images adapted to being fitted seamlessly together.
