Constructor Detail

ModelFromLas

public ModelFromLas(File file,
                    LidarPointSelection lidarPointSelection)

Construct a model tied to the specified file with filtering based on classification (only points of specified class are accepted).

Parameters:

file - a valid LAS file

lidarPointSelection - a specification for selecting lidar points based on their classification or other elements.

Method Detail

load

public void load(IMonitorWithCancellation monitor)
          throws IOException

Read the standard header of the LAS file associated with this model and all internal records to create a collection of vertices.

Specified by:

load in interface IModel

Overrides:

load in class ModelAdapter

Parameters:

monitor - an optional monitor for tracking progress (null if not used)

Throws:

IOException - In the event of a non-recoverable error related to I/O or file access.

getDescription

public String getDescription()

Description copied from interface: IModel

Gets a shortdescription of the model

Specified by:

getDescription in interface IModel

Overrides:

getDescription in class ModelAdapter

Returns:

a valid string.

getLidarPointSelection

public LidarPointSelection getLidarPointSelection()

Gets the point selection option used to load the model.

Returns:

a valid enumeration instance

getLinearUnits

public LinearUnits getLinearUnits()

Gets the linear units for the coordinate system used by the data. It is assumed that the vertical and horizontal coordinate systems will be in the same unit system, though assumption could change in a future implementation.

Specified by:

getLinearUnits in interface IModel

Overrides:

getLinearUnits in class ModelAdapter

Returns:

a valid enumeration instance

toString

public String toString()

Overrides:

toString in class Object
