Hey guys
I am currently working on a project that will take 3D pint cloud Lidar data from the USGS site and I need to convert it into a model that can be read by Lightwave.
The source of the data is the USGS site:
https://viewer.nationalmap.gov/basic/

I plan to complement the Lidar data with DEM maps.
So any tips you guy can send my way?

Thanks

Hey Robert,

I do a lot of map work with Lightwave and a few other programs, plugins and data-sets. Here's a summary of my work-flow:

1. Data Source: http://www.viewfinderpanoramas.org/Coverage%20map%20viewfinderpanoramas_org3.htm
2. Map prep: 3DEM Software for Terrain Visualization ver 2.0: http://freegeographytools.com/2009/3dem-website-is-gone-but-3dem-still-available-here
3. Export high-res terrain elevation color map BMP, TGA or TIFF and a DEM file
4. Use "Ground Control" Lightwave plugin for DEM import to create mesh (great plugin!!!!)
5. Scale object to real-world dimensions, apply color map as a planar projection on Y axis

Here's what my end results look like:
