HI i have point xyz and can make LAS dataset?
I don't have any video explaining the steps, but if you can share the, let's say' first 100 records of the XYZ file, I can see if I can provide some more explanation on the steps to accomplish this.
OK, so you run the tool. It ends "successfully", but does not create any output file (so it does not work). To understand what is happening, I would have to get access to the file you are using and see a screenshot of the settings you use in the tool. Start with sharing a screenshot of the tool configuration. By that I mean this screen:
Yes look ok but when I do add the folder it's empty so what can I do for more...
Sent from my Samsung Galaxy smartphone.
Judging from the screenshot you provided, you are able to successfully run the tool and create the LAS file. Do you have any other question?
hi
I will try to make your example with other point but doesnt work for more now i will send my work
please attach folden to understand what i have done
No problem.
So, you first go the website I mentioned before:
LAStools: converting, filtering, viewing, processing, and compressing LIDAR data in LAS format
You can scroll down to the tool txt2las.exe and click it (or any other tool, since it will download a ZIP with all the tools):
Or use this direct link:
http://lastools.org/download/LAStools.zip
When you open the ZIP, you will notice that there is a large amount of information in it: In the LASTOOLS folder you will see a LICENSE.TXT file and you can verify that the txt2las is free:
This part of LAStools is "free" open-source LGPL (see COPYING.txt). To purchase a different licensing model contact 'license@rapidlasso.com'. * laszip * lasindex * lasvalidate * lasliberate * lasinfo * las2las * lasdiff * lasmerge * las2txt & txt2las * lasprecision * LASzip (with static linking exception) * LASlib (with LASzip) - the API used by LAStools.<SPAN class="line-numbers-rows"><SPAN></SPAN><SPAN></SPAN><SPAN></SPAN><SPAN></SPAN><SPAN></SPAN><SPAN></SPAN><SPAN></SPAN><SPAN></SPAN><SPAN></SPAN><SPAN></SPAN><SPAN></SPAN><SPAN></SPAN><SPAN></SPAN><SPAN></SPAN><SPAN></SPAN></SPAN>
What you will also see, is that Martin Isenburg has included a toolbox that allows you to process the data directly in ArcGIS.
If you unzip the files to a local folder, you can navigate to the folder and find the LAStools.tbx. Inside you will find the tool txt2las. Double click to open the tool:
Before you load the tool, you will need to change the decimal sign into a dot, since the comma will be interpreted as a field separator and mess up the result. So, if you can, open the text file and change the decimal sign from coma to a dot:
When we look at order of the fields we will see, this order:
Y X skip Z
This is something that we will need to specify in the tool in order to interpret the data correctly:
So open the tool (if you haven't already) and specify the following:
When you run the tool it will generate the LAS file and it will be loaded to ArcMap (at least in 10.6 it will):
When we identify a LAS point and compare it with the input data it corresponds:
IF IT ISNT PROBLEM USE ORTHOMTRIC ELEVATION
I notice that you have 2 elevation values. Which one do you want to use in the output LAS file?
Is your decimal sign really a comma? This might need to be changed to point before processing the file, but I will confirm this.
HI
ATTACH FILE DOC
have you any example video ?
I have done this in the past using LAStools (LAStools: converting, filtering, viewing, processing, and compressing LIDAR data in LAS format ). See a description here:https://community.esri.com/thread/34075#comment-210089
According to the discussion in the idea: Ability to convert xyz point data to LAS format It should be part of the Data Interop extension.
