Point Cloud
Select Survey | Import | Point Cloud to import point cloud data in LAS, Leica (PTS and PTX), or PLY file format.
The filtering mechanisms available for selection on the Survey | Point Cloud Filter menu enable point cloud data to be imported and processed more efficiently. See: Point Cloud Filter
Input
Double-click, or click on the Select icon, to navigate to the location of the PLY, LAS/LAZ, or Leica Cyclone point cloud files you want to import.
You can limit the file selection using an All Point Cloud file types filter. Choosing the All Files filter will allow PDAL-compatible files, such as JPEG and TIFF files, to be selected.
Reduce the number of points to
Point cloud data often comprises millions to billions of 3D points. Select this check box to reduce the number of points by expressing a filter value of <n> million points.
This will speed up processing for very large datasets, but at the expense of memory.
Output
File
Enter, or double-click (or click on the Select icon) to select, the name of the Output file. This will typically be a .DAT file containing assay point data.
East, North, and Z fields
Specify the names of the point coordinate fields in the Output file.
Classification field
(Optional) If you specify a field name, point classifications (as per the LAS specification) will be written to the Output file as 3-width character values. To write all dimensions to the Output file, see: Import Additional fields (below).
Intensity field
(Optional) If you specify a field name, PDAL intensity dimensions will be written to this field. To write all dimensions to the Output file, see: Import Additional fields (below).
Colour field
When a Colour field is specified, the import process will combine Red, Green and Blue colour values and write a single value to that field. If the input colour is a 16-bit colour, it will be downsampled to an 8-bit colour.
If a Colour field is unspecified and the Import additional fields check box is selected, the colour will be imported as values in three separate R, G, B fields. These colours could be 8-bit or 16-bit, depending on the input file.
colored 3D point cloud also called RGB-D image,
(Optional) If you specify a field name, PDAL RGB colour dimensions will be written to the Output file. To write all dimensions to the Output file, see: Import Additional fields (below).
Import additional fields
Select this check box to write PDAL dimension data to the Output file. The dimensions written to the Output file will depend on the input reader used to create the input data.
If the Intensity field, Classification field, or Colour field is left blank and the Import additional fields option is selected, PDAL Intensity, Classification, or Colour (Red, Green, Blue) dimensions are written to the Output file.
Auto load
Select this option to open the imported points as a Point layer in Vizex.
