LAS Dataset Toolbar greyed out

[ElenaElena]

Hi everyone,

I am working with Lidar data but having problems with LAS Dataset toolbar - it's actually greyed out.3D Analyst seems to work fine, I was able to use LAS to Multipoint and LAS Dataset to TIN tools. But I cannot apply filters from the LAS Dataset toolbar or draw a profile or to select different representations of elevation, neither to .las nor to .lasd. Any ideas of why this may happen?

I would very much appreciate your help.

So the help topic suggests you have turned on the 3D extension at least The interactive LAS Dataset toolbar—Help | ArcGIS for Desktop and an appropriate layer selected in the table of contents? 

LAS dataset Profile View—Help | ArcGIS for Desktop

Under the customize menu > extensions > is the 3D Analyst extension turned on?

Simple solution and so easy to forget when you don't work with these datasets on a regular basis. Thanks

Hi Elena,

Check this out

LAS Dataset questions ArcMap 10.1 and ArcScene 10.1

When creating an LAS Dataset through ArcToolbox, I would add all of my .las tiles, then choose a coordinate system, but did NOT check the box "Calculate Statistics" before creating the dataset. I'd then end up calculating statistics later using ArcCatalog. Every time I did this, the Profile View in the LAS Dataset Toolbar did not work and showed up as greyed out.

However, when I created my LAS Dataset and checked the "Calculate Statistics" box in the ArcToolbox dialog box, the Profile View then worked

And to underline the point...

You cannot actually see a *.las dataset directly, they have to be loaded into a *.lasd dataset, created in ArcCatalog first. And statistics should be done.

Thank you, Jayanta. This for the reason in my case as well.
