HOW TO: Quick start on ConvertCMD

Converting files with ConvertCMD

ConvertCMD Overview

udStreamConvertCMD should be part of the files you downloaded with udStream. Alternatively, you also convert using the udStream Desktop.

You can run this via command line or any terminal/shell program you are currently using with the following command:   


For multiple files, you can opt to add multiple -i <File URL> or create a txt file with the list of the URLs that you want converted. Then replace -i with - ilist :  

-i <inputFile>
Add an input to the convert job. More files can be specified immediately after, folders will be searched for supported files recursively 
-ilist <file> 
Add inputs from a text file that has 1 input file per line 
 -isrid <file>Override the input srid code for geolcation for any input files that come AFTER this setting is set
-resolution <res>  
Override the resolution (0.01 = 1cm, 0.001 = 1mm)
-srid <sridCode> 
Override the srid code for geolocation 
-globalOffset <x,y,z> 
Add an offset to all points, no spaces allowed in the x,y,z value
Require enter key to be pressed before exiting
 If any error occurs, require enter key to be pressed before exiting
-procyURL <url>
Set the proxy URL
-proxyUsername <username>
Set the username to use with the proxy
-proxyPassword <password>
Set the password to use with the proxy
-copyright <details>
Adds the copyright information to the "Copyright" metadata field
Does a small test to test if positioning/geolocation is correct
Parameters to export the region. Example: -region 0.0 0.0 0.0 1.0 1.0 1.0
Include the primitives (triangles etc) from supported file formats
-ignore <attribute 1> <attribute 2>
Ignore the specified UDS Attribute when exporting, add one space between attributes
Token to access private cloud-based files
-o <outputfile.uds>
UDS output file path and file name

You need go to the Command Prompt to do the conversion. Type CMD in the search area, change directory to the folder of udStreamConvertCMDeg:  

C:\Users\Username CD C:\Program Files\Euclideon\udStream1.4>udStreamConvertCMD.exe <username> <password> -i “E:\demo files\sample dataset.las” - resolution 0.001 -ignore udGPSTime  udReturnNumber -o “E:\demo data\sample dataset.uds   

The output file location should be in your local computer/external HD. Additionally, it will need to create a temp folder (this defaults to the location where you run the command) to store temp files. This gets deleted after conversion is done. Make sure you have enough space for both the temporary files and output file, a rule of thumb is to have at least 10-50 times of the original data size.     

Using an ilist

As mentioned above, as an alternative to manually inputting files, you can create an ilist to load all input files. an ilist is a txt file that contain all of the input destination files. ConvertCMD allows input from either local storage as well as public files in cloud storage.
