Terrain Analysis EngineClass TLcdTerrainSegmentScanner

java.lang.Object

com.luciad.tea.TLcdTerrainSegmentScanner

All Implemented Interfaces:

ILcdSegmentScanner

public class TLcdTerrainSegmentScanner
extends Object
implements ILcdSegmentScanner

This is a utility class for scanning terrain elevation along a line segment. The function that is passed as an argument to the scan-methods gets a 3D point as an argument: the (x,y) coordinates give the position of the point being scanned, while the z-coordinate gives the terrain elevation for this point.
