These are contained in the READSUPPORTEDOPTIONS module level variable.
| Name |

|---|
| POINT_FROM |
an integer. Set to one of the POINT_FROM_*
module level constants. Determines which
file the coordinates for the point is
created from. Defaults to POINT_FROM_ANCHOR |
for new files
-
pylidar.lidarformats.pulsewaves.POINT_FROM_TARGET = None
How the points are set
-
class
pylidar.lidarformats.pulsewaves.PulseWavesFile(fname, mode, controls, userClass)[source]
Reader/Writer for PulseWaves files
-
close()[source]
Write any updated spatial index and close any file handles.
-
static
getDriverName()[source]
Get header as a dictionary
Just extract the one value and return it
-
getTotalNumberPulses()[source]
Return the total number of pulses
-
hasSpatialIndex()[source]
PulseWaves does not have a spatial index
-
readData(extent=None)[source]
Internal method. Just reads into the self.last* fields
-
readPointsByPulse(colNames=None)[source]
Return a 2d masked structured array of point that matches
the pulses.
-
readPointsForRange(colNames=None)[source]
Reads the points for the current range. Returns a 1d array.
Returns an empty array if range is outside of the current file.
colNames can be a list of column names to return. By default
all columns are returned.
-
readPulsesForRange(colNames=None)[source]
Reads the pulses for the current range. Returns a 1d array.
Returns an empty array if range is outside of the current file.
colNames can be a list of column names to return. By default
all columns are returned.
-
readReceived()[source]
Read the received waveform for all pulses
returns a 2d masked array
-
readTransmitted()[source]
Read the transmitted waveform for all pulses
returns a 3d masked array.
-
readWaveformInfo()[source]
2d structured masked array containing information
about the waveforms.
Update our cached dictionary
Just update one value in the header
-
setPulseRange(pulseRange)[source]
Sets the PulseRange object to use for non spatial
reads/writes.
-
writeData(pulses=None, points=None, transmitted=None, received=None, waveformInfo=None)[source]
Write all the updated data. Pass None for data that do not need to be up
It is assumed that each parameter has been read by the reading functions
-
class
pylidar.lidarformats.pulsewaves.PulseWavesFileInfo(fname)[source]
Class that gets information about a PulseWaves file
and makes it available as fields.
-
static
getDriverName()[source]
-
pylidar.lidarformats.pulsewaves.READSUPPORTEDOPTIONS = ('POINT_FROM',)
Supported read options
-
pylidar.lidarformats.pulsewaves.isPulseWavesFile(fname)[source]
Helper function that looks at the start of the file
to determine if it is a pulsewaves file or not
