Class TLcdRasterHeightProvider

java.lang.Object
com.luciad.util.height.TLcdRasterHeightProvider
All Implemented Interfaces:
ILcdBounded, ILcdHeightProvider

public class TLcdRasterHeightProvider extends Object implements ILcdHeightProvider
This height provider retrieves its heights from a given raster.
Since:
9.1
  • Constructor Details

    • TLcdRasterHeightProvider

      public TLcdRasterHeightProvider(ILcdRaster aRaster)
      Creates a new height provider based on the given raster. Raster heights outside the range of -12000 to 10000 are returned as invalid (Double.NaN).
      Parameters:
      aRaster - the raster from which the heights will be retrieved.
    • TLcdRasterHeightProvider

      public TLcdRasterHeightProvider(ILcdRaster aRaster, int aMinValidHeight, int aMaxValidHeight)
      Creates a new height provider based on the given raster. Raster heights outside the given range are returned as invalid (Double.NaN).
      Parameters:
      aRaster - the raster from which the heights will be retrieved.
      aMinValidHeight - the minimum valid height.
      aMaxValidHeight - the maximum valid height.

    • retrieveHeightAt

      public double retrieveHeightAt(ILcdPoint aPoint)
      Description copied from interface: ILcdHeightProvider
      Returns the height at the given point.
      Specified by:
      retrieveHeightAt in interface ILcdHeightProvider
      Parameters:
      aPoint - a 2D point, in the horizontal reference that is determined by the implementation.
      Returns:
      the elevation at the given point, in the vertical reference that is determined by the implementation. The value may also be Double.NaN, if the elevation is not known.
    • getBounds

      public ILcdBounds getBounds()
      Description copied from interface: ILcdBounded
      Returns the ILcdBounds by which the geometry of this ILcdBounded object is bounded.

      If the geometry does not allow retrieving valid bounds (for example a polyline with 0 points) the return value is unspecified. It is highly recommended to return an undefined bounds. You can create undefined bounds using the default constructors of TLcdLonLatBounds or TLcdXYBounds.

      Specified by:
      getBounds in interface ILcdBounded
      Returns:
      the ILcdBounds by which the geometry of this ILcdBounded object is bounded.
