ElevationModel

public interface ElevationModelInterface

Defines an generic inteface between the ElevationModel and other objects that require its characteristics for display purposes.

Method Summary

float	getElevationAt(float x, float z) Fetches the elevation at a particular location on the terrain map given the x,z coordinates.
float	getMaxElevation() retrieve the model maximum elevation, adjusted by the elevation exageration
float	getMinElevation() retrieve the model minimum elevation, adjusted by the elevation exageration
float	getModelLength() retrieve the model length, distance in meters from west to east
float	getModelWidth() retrieve the model width, distance in meters from south to north

Method Detail

getElevationAt

float getElevationAt(float x,
                     float z)

Fetches the elevation at a particular location on the terrain map given the x,z coordinates. X,Z coordinates represent the distance in meters from the center of the terrain image.

Parameters:

x - x coordinate

z - z coordinate

Returns:

the elevation (y coordinate) in meters (adjusted for exageration)

getModelLength

float getModelLength()

retrieve the model length, distance in meters from west to east

Returns:

the length in meters

getModelWidth

float getModelWidth()

retrieve the model width, distance in meters from south to north

Returns:

the width in meters

getMaxElevation

float getMaxElevation()

retrieve the model maximum elevation, adjusted by the elevation exageration

Returns:

the adjusted maximum elevation in meters

getMinElevation

float getMinElevation()

retrieve the model minimum elevation, adjusted by the elevation exageration

Returns:

the adjusted minimum elevation in meters
