Summary
The Describe function returns the following properties for LAS dataset files. The File and Dataset property groups are also supported.
For an LAS dataset, the Describe dataType property returns a value of "LasDataset".
Properties
Property | Explanation | Data Type |
constraintCount (Read Only) | The number of surface constraint features referenced by the LAS dataset. | Long |
fileCount (Read Only) | The number of LAS files referenced by the LAS dataset. | Long |
hasStatistics (Read Only) | Indicates whether statistics had been calculated for the LAS files referenced by the LAS dataset. | Boolean |
needsUpdateStatistics (Read Only) | Indicates whether statistics are out of date or had not been calculated. Returns false if statistics are up to date. | Boolean |
pointCount (Read Only) | The number of data points in the LAS files referenced by the LAS dataset. | Long |
usesRelativePath (Read Only) | Indicates whether the LAS dataset references its data elements using relative paths. | Boolean |
Code sample
The following script demonstrates the application of LAS dataset properties:
import arcpy
desc = arcpy.Describe(r'E:\GIS_Data\lidar\test_bmore.lasd')
if desc.usesRelativePath:
pathType = 'Relative'
else: pathType = 'Absolute'
# Determine state of statistics
if desc.needsUpdateStatistics:
if desc.hasStatistics:
statistics = 'Out-of-date'
else:
statistics = 'Missing'
else:
statistics = 'Current'
print('LAS Dataset Name: {0} \r'\
'Point Count: {1} \r'\
'Surface Constraint Count: {2} \r'\
'Path Type: {3} \r'\
'Statistics Status: {4}'.format(desc.basename, desc.pointCount,
desc.constraintCount, pathType,
statistics))
