Creating las dataset problems with references

JoyceWakker — Tue, 05 Feb 2013 09:28:24 GMT

Hi,

I have a series of .las files with classification code 1 (unassigned) and 2 (ground).
I want to create a las dataset but in the 3D view I just see red blocks. What information is missing?
It seems to me that there is no spatial reference on the .las files. I did add it but it does not help.

Thanks for some advice,
Joyce

I found that the red blocks show up if your .las files are to big. Cirka 32000kB works well.

If all you are seeing is the outline or the 'red squares' you mentioned then I would encourage you to look at the % of visibility in the table of contents above your LAS dataset. If it says 0% then I would encourage you to zoom in on it until you start seeing data or adjust the settings. You are correct that the size and the projection are important, but I would pay more attention to the % visibility under the rendering preferences.
