Using LAS 1.2 specification data in 9.3

FelipeAvila — Fri, 01 Oct 2010 19:47:33 GMT

3D analyst for 9.3 does not seem to support LAS 1.2 spec data when trying to convert a LAS file to a multipoint feature. Is there a work around for this or can Arc 10 handle this format?
Thanks

Hi,

another way to inport .las file is to convert it to .txt file.
I use lastools, open source tool available online.

convert las to txt extracting x,y,z and other data you need in .csv format

then add a header using txt editor e.g. x,y,z,i

import .txt file to arcgis
plot x y point
export data and save as .shp

for large file importing and savisng in arcgis might take some time

Regards,
