Constructor Detail

VertexWithClassification

public VertexWithClassification(double x,
                                double y,
                                double z,
                                int index,
                                int classification)

Constructs a vertex with the lidar classification value extracted from the source file. The ASPRS spec allows for classification codes from 0 to 255. It formally defines values 0 to 18 (with up to 63 reserved for future use) and leaves the rest as user definable. Here are the main ones:

0. Created, never classified
1. Unclassified
2. Ground
3. Low vegetation
4. Medium vegetation
5. High vegetation
6. Building
7. Low point (noise)
8. Reserved
9. Water

Parameters:

x - the X horizontal coordinate for the lidar sample point

y - the Y horizontal coordinate for the lidar sample point

z - the vertical coordinate for the lidar sample point

index - the record number for the lidar sample point

classification - the classification value assigned to the lidar sample point.

Method Detail

getClassification

public int getClassification()

Gets the classification code indicating the kind of feature from which the sample was captured.

Returns:

an integer value in the range zero to 255, usually in the range 0 to 9.

toString

public String toString()

Overrides:
