Point location conversion in distance cartogram construction based on vector field analysis

<p>Distance cartograms are deformed maps in which the distance of each of the preselected point pairs in the geographic map is changed in step with a specified value such as a travel time. In distance cartogram construction, the preselected points are fixed in the first step whereas the locations of other points are converted in the second step. This paper proposes a new point location conversion method for the second step. The conversion process is modeled as a phenomenon in a three-dimensional vector field. Each point in the geographic map is connected with the corresponding point in the cartogram by a streamline of the field. The connection relationship becomes a smooth homeomorphism required in distance cartogram construction. The experimental results demonstrate its effectiveness.</p>
