Can we Digitize a .Las format file in Arc Map ? and can we able to gave 3D x,y,z Values to that Digitized data ?

This is Shaik Riyaz from India.

I want to know that

can we Digitize polyline/point features with 3D x,y,z values by ".Las Format file" in Arc map?

If we can able to do so..

then please explain me how to do ..

Thanks and Regards

Hi Shaik, I'm not sure what you are trying to do. LAS files store lidar data. Are you wanting to create breaklines or other features on top of lidar data stored in a LAS file? If so, have a look at this help topic: Creating a LAS dataset—Help | ArcGIS Desktop. If you're asking how to create a LAS file from xyz data, this thread may be useful: How do I create a simple 3d model using xyz or las files

Hello mam

Thank you for your response.


i had a .LAS file ( a Point cloud data)

for that i want to do Digitization (mark point and polyline features)


for that digitized features , i want to gave x,y,z values...

so please tell me the procedure step by step

how to do so in  Arc Map?

Hello Shaik,

If it's a small area, you could create a last return DSM from the lidar using the Local Government 3D Basemaps tools and use that to create building footprints in 2D in ArcGIS Pro.   Then use the tasks in the Local Government 3D Basemaps to make the buildings 3D.   You can also use the tools in Local Government 3D Basemaps to create 3D Trees as multipatch polygons or use the Trees from Lidar tool to create points with 3D attributes to support the Add Preset Data - Realistic Trees.   With  Trees from Lidar tool, it creates a all high points featureclass that has all the high points extracted.   

If you have large volumes of buildings to collect, I suggest using Classify LAS Buildings tool on the lidar (if it is not classified for buildings). Then use the building extraction tools for creating 2D buildings and make them 3D using Local Government 3D Basemaps.
