Points In (PoiIn)
Type: Translator
Translates LiDAR point lists into VrOne files.
The Points In translator converts LiDAR data contained in an ASCII file into the Vr Mapping database as Vr Points. The data fields that may be converted are X, Y, Z, Intensity, Red, Green, Blue. The Vr Points structure in Vr Mapping may contain up to 16 attributes per point. The LAS format also contains up to 16 attributes per point and should be used if possible instead of the Points In translator. Since the Points format is ASCII, the Points In and Points Out translators are significantly slower than the LAS In and LAS Out translators.
The ASCII In translator may be used to import XYZ coordinates into Vr Mapping but it does not support point attributes.
Loads previously recorded Points In (.poi) parameter file.
Records current translation parameters to a Points In (.poi) parameter file.
Allows Points input files to be selected. Also allows a VrOne output file to be defined for each input file. Looks for files with an extension of .pts by default, but will attempt to read in any file chosen.
The VrOne output filenames will only be used if the "Translate to separate VrOne files" option is on.
The Define Input Filenames dialog box
Add Files
Pressing this button will be display a standard VrOne file selection dialog. All files selected will be added to the list of Input files. A VrOne output filename will be generated based on each input filename.
Remove All
Pressing this button will remove all files from the Input file table.
Change Output Directory
Allows the changing on the output directory (folder). By default the output directory is the same as the input file directory
Allows editing of general translation parameters.
The Edit Parameters dialog Box
Translate to separate VrOne files?
If this is on, then each Points input file will be translated to a separate VrOne file. The Input to Output filename cross-reference is set in the "Define Input Filenames" dialog.
Input format
Defines the format of the input files and the fields to be translated.
| • | X Y Z I R G B - X, Y, Z, Intensity, Red, Green, Blue |
| • | X Y Z I - X, Y, Z, Intensity |
| • | X Y Z R G B - X, Y, Z, Red, Green, Blue |
| • | X Y Z - X, Y, Z |
The range for the intensity field is 0-32767. An intensity shift value may be set in cases when there are negative intensity values. RGB values may range from 0 to 255.
First record is point count
If this parameter is checked then the number of points should be the first record of each input file.
Shift value for intensity
The valid range for intensity in the Vr Point format is 0-32767. The shift value will be added to all incoming intensity values and may be used in the case of negative intensity values.
Target scale for new VrOne files (1:n)
If the "Translate to separate VrOne files?" is on, and a VrOne file does not exist during translation, then this Target scale will be used when creating the new VrOne file.
Layer for points
Points that are translated will be placed in the layer defined.
Scans a single Points file and displays the first 100 lines. This may be used to determine the input format of the Points files.
Begins the file translation process. All files that were defined by the “Define input Filenames” option will be imported.
The Translation information box
Starts the browser and displays the current help document.
Quits Points In and gives an option to save the current parameters if they have been changed.
