Interface ILcdLineOfSightCoverage

All Superinterfaces:

ILcdBounded, ILcdCache, ILcdRaster

All Known Subinterfaces:

ILcdExtendedLineOfSightCoverage

public interface ILcdLineOfSightCoverage
extends ILcdRaster

Represents the result of line-of-sight computations. Its center represents the point from which these computations were performed. It represents the results in an arc, starting from a start angle and extending over an arc angle, and contained within a maximum radius. The view is also limited by a minimum and maximum angle in the vertical direction.

The parameters of the arc can only be read, not modified.

Method Details

getCenter

ILcdPoint getCenter()

Returns the center, this is the point from which the line-of-sight computations were performed. Only X- and Y-coordinates should be taken into account.

Returns:

The center, i.e. the point from which the line-of-sight computations were performed. Only X- and Y-coordinates should be taken into account.

getHeightAboveGround

double getHeightAboveGround()

Returns the height above the ground of the center.

Returns:

The height above the ground of the center.

getArcAngle

double getArcAngle()

Returns the angle extent of the coverage. The angle is measured in degrees and positive clockwise.

Returns:

The angle extent of the coverage. The angle is measured in degrees and positive clockwise.

getAngleStepsize

double getAngleStepsize()

Returns the angular discretization step size in degrees.

Returns:

The angular discretization step size in degrees.

getMaxRadius

double getMaxRadius()

Returns the maximum radial extent of the coverage in meter.
