Interface ILcdCrossCountryDistanceFunction

All Known Implementing Classes:
ALcdCrossCountryHeightProviderDistanceFunction, ALcdCrossCountryRasterDistanceFunction
public interface ILcdCrossCountryDistanceFunction
A ILcdCrossCountryDistanceFunction calculates distances between two given points. In general this distance can be of all kinds: it can be an exact distance, or an estimate, an Euclidean distance or a time cost, ... The exact requirements for a distance function, if any, shall be specified at the place where the distance function is used.

  • Method Details

    • computeDistance

      double computeDistance(ILcdPoint aStartPoint, ILcdPoint aEndPoint)
      Returns the distance between 2 points. These points should both be inside the bounds of this distance function.
      Parameters:
      aStartPoint - the start point.
      aEndPoint - the end point.
      Returns:
      the distance from aStartPoint to aEndPoint.

    • getBounds

      ILcdBounds getBounds()
      Returns the bounds in which this function can compute distances.
      Returns:
      the bounds in which this function can compute distances.
