Method for displaying a position on a map
First Claim
1. A computer-implemented method for displaying a position on a map, the method executable by an electronic device causing displaying of the map, the method comprising:
- appreciating coordinates of the position;
appreciating coordinates of an object having a curve near the position;
identifying a point of the curve nearest to the position, said identifying comprisingidentifying a first segment of the curve bounded by a first region and a second segment of the curve bounded by a second region;
whereinidentifying the first segment of the curve bounded by the first region and the second segment of the curve bounded by the second region comprises dividing a monotonic segment of the curve into segments including the first segment and the second segment; and
whereindividing the monotonic segment of the curve into segments including the first segment and the second segment comprises dividing the monotonic segment of the curve into segments including the first segment and the second segment such that the second segment monotonically progresses away from the position from a known nearest point of the second regiondetermining that a distance from the position to a point of the first segment is not greater than a distance from the position to a known nearest point of the second region; and
calculating a shortest distance from the position to the first segment as a shortest distance from the position to either of the first segment and the second segment without calculating a distance from the position to at least one point of the second segment other than the known nearest point of the second region; and
causing displaying, on the map, of an indication of the point of the curve nearest to the position.

Abstract
There is disclosed a method executable by an electronic device for displaying a position on a map. The method comprises appreciating coordinates of position; appreciating coordinates of a map object having a curve near position; identifying a point of curve nearest to position comprising identifying a first segment of curve bounded by a first region and a second segment of curve bounded by a second region, determining that a distance from position to a point of first segment is not greater than a distance from position to a known nearest point of second region, and calculating a shortest distance from position to first segment as a shortest distance from position to either of first segment and second segment without calculating a distance from position to at least one point of second segment other than known nearest point of second region; and causing displaying, on map, of an indication of point of curve nearest to position.
