Detailed Description

The PointReader class is the base class for reading LiDAR file formats. It add one method to the PointSource interface, getFileFormatString().

Definition at line 27 of file PointReader.h.

Member Function Documentation

§ getBounds()

const Bounds& PointReader::getBounds ( void ) const

virtual

This method returns the geo bounding box of the point cloud.

Implements PointSource.

§ getClassIdNames()

char const* const* PointReader::getClassIdNames ( void ) const

virtual

This methods returns an array of classification names with length getNumClassIdNames().

Implements PointSource.

§ getFileFormatString()

virtual const char* PointReader::getFileFormatString ( void ) const

pure virtual

This method returns a string the contains the File Type and version of the PointReader. For example for a MrSID file this will will return "MG4 4.0.0.1".

Implemented in TXTPointReader, and MG4PointReader.

§ getNumClassIdNames()

size_t PointReader::getNumClassIdNames ( void ) const

virtual

This methods returns the number of classification names.

Implements PointSource.

§ getNumPoints()

count_type PointReader::getNumPoints ( void ) const

virtual

This method returns the number of points in the point cloud.

Implements PointSource.

§ getOffset()

const double* PointReader::getOffset ( void ) const

virtual

This method returns the quantization offset for X, Y, and Z channels. It returns NULL then the point cloud is not quantized or quantization is unknown.

Implements PointSource.

§ getPointInfo()

const PointInfo& PointReader::getPointInfo ( void ) const

virtual

This method returns a PointInfo object.

Implements PointSource.

§ getScale()

const double* PointReader::getScale ( void ) const

virtual

This method returns the quantization scale factors for X, Y, and Z channels. It returns NULL then the point cloud is not quantized or quantization is unknown.

Implements PointSource.

§ getTotalWork()

double PointReader::getTotalWork	(	const Bounds &	bounds,
		double	fraction
	)		const

virtual

This method returns the amount of work needed to decode the points in bounds. getTotalWork() is used with ProgressDelegate to track the progress of a decode or encode.

Parameters

bounds	the region of interest
fraction	the fraction of the points you want (use 1.0 for all the points and use 0.1 to keep every tenth point)

Returns: the work needed to decode bounds

Implements PointSource.

Reimplemented in TXTPointReader.

§ getWKT()

const char* PointReader::getWKT ( void ) const

virtual

This method returns the spatial reference system as a Well Known Text (WKT) string. If the PointSource does not have a spatial reference system it will return NULL.

Implements PointSource.

§ overrideWKT()

void PointReader::overrideWKT ( const char * wkt )

§ setBounds()

void PointReader::setBounds ( const Bounds & bounds )

protected

This method sets the bounding box of the point cloud. All subclasses must call this function in thier init() function.

Parameters

bounds the bounding box of the point cloud.

See also: getBounds()

§ setNumPoints()

void PointReader::setNumPoints ( count_type numPoints )

protected

This method sets the number of points in the point cloud. All subclasses must call this function in thier init() function.

Parameters

numPoints the number of points in the point cloud

See also: getNumPoints()

§ setPointInfo()

void PointReader::setPointInfo ( const PointInfo & pointInfo )

protected

This method sets the channel information. All subclasses must call this function in thier init() function.

Parameters

pointInfo the channel information

See also: getPointInfo()

§ setQuantization()

void PointReader::setQuantization	(	const double	scale[3],
		const double	offset[3]
	)

protected

This method sets the quantization scale and offset for the point cloud. If the data is not quantized do not call this function or call it with scale = NULL and offset = NULL.

Parameters

scale	the quantization scale for the X, Y, and Z channels
offset	the offset for the X, Y, and Z channels

See also: getScale(); getOffset()

§ setWKT()

void PointReader::setWKT ( const char * wkt )

protected

This method uses a Well Known Test (WKT) string to set the spatial reference system.

Parameters

wkt	the WKT representation of the spatial reference system

See also: getWKT()
