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.
§ 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 |
§ 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 |
§ 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
