Tahoe NAIP draped on LiDAR DEM

I'm amazed by how well Global Mapper works with immense data sets.

Here are some renders of 2010 NAIP imagery for the Lake Tahoe Basin. Both the LiDAR derived 0.5 meter DEM and the 1 meter NAIP (enhanced to 0.5 m) are full basin datasets.

    Wow that is pretty impressive looking. That high-res Lidar data really makes things look great! I'm guessing you also bumped up the resolution of the terrain and texture layers in the 3D view options right?

    Thanks,

    Mike,

    Yes, I put the terrain at the maximum 8K and the texture map at 4K. Pretty responsive. For some reason 3D viewer won't work if I set texture at 8K, generates an access violation message. On Win7 64, i7, 8 GB RAM, 5570 Radeon w/ 1GB.

    Maybe see you in Denver, debating with myself whether to attend for exhibits only.

    The video card limits how large the terrain and texture sizes can go. Unfortunately I don't know of a way to tell up front how large they can get and I can't find a way to gracefully fail when they get too large since the allocation is done outside of my control.

    I should be at the ILMF show later this month, hanging around the Blue Marble booth for the most part.

    Thanks,
