take a look at the lidar white paper from Esri. It predates the las data set but covers your questions about multipoints to terrain.
hope this helps
Gordon, this topic got remade after the transfer to GeoNET, and was answered on this thread
Would like to get rasters into a USGS .dem file.
Thanks for the extra info though!
I hope this helps.
try page 13 below multipoint to terrain
check out this lab our team made to address multipoint in 10.2
A quick how to we made on working with Lidar in ArcGIS
Thanks so much for the info guys! Since I've started working with the multipoints which we accquired from a vendor, I've figured out how to bring them into a feature class and convert them to a raster dataset, then bring the raster images into global mapper and export them out to a DEM file. Which is what I was trying to figure out when I started this thread. But I've also learned how to create las files in Global Mapper and create a terrain dataset from the multipoints.
Thanks for all the help!
Good luck scott, sounds like a lot of work.
I've used LASTOOLs quite a bit and they can be very useful.
The Alaska Division of Geological & Geophysical Surveys used LASzip successfully in an interactive map called LiDAR Datasets of Alaska.
