LAS File question

jonathantuscanes — Thu, 16 Dec 2010 15:43:47 GMT

I am trying to export a point file (with elevations) from my LAS files. I have used the 'LAS to multipoint' tool with success. However, the tool does NOT give me the elevation values. Does anyone have any experience with this?

Have you tried calc'ing the z values to a field?

I am not sure what you mean?

You have a point layer. You open the table and add a field and then you right click on the field and hit calculate geometry and choose the z coordinate from the drop down

Hello Jon,

The Multipart to Singlepart tool in ArcToolbox > Data Management Tools > Features toolset can be used to generate the individual point features from your multipoint dataset. Once this is done, you can use the field calculator to populate the z-values or use the Add XY Coordinates tool, which would add the X, Y, and Z values as new fields to the attribute table of the single point feature class. It may be preferable to use the field calculator so that you don't have to deal with unecessary fields (X and Y values).

I'm a bit curious about your objective in having the Z values attributed. Please share if you don't mind doing so... perhaps there is a more elegant solution that can be adopted.

Regards,
Khalid
