Techniques for drawing geodetic polygons |
摘要 |
Techniques in a data processor for drawing on a map a geodetic polygon that straddles a splitting meridian include, in one embodiment, maintaining data that represents the geodetic polygon, the data comprising a set of geographic coordinates; transforming the set of geographic coordinates into a set of planar coordinates representing a planar polygon; splitting the planar polygon into a plurality of sub-figures; shifting at least one sub-figure of the plurality of sub-figures along a horizontal axis of two-dimensional plane to produce a shifted sub-figure; and causing the shifted sub-figure to be displayed on a map concurrently with at least one other sub-figure of the plurality of sub-figures that was not shifted. |
