Google Earth Lidar Layer DEM levels

[gsully]

I think I understand all the necessary steps and pulled in a few Lidar layers into Google Earth, but the problem I'm having is resolution. The 1 meter DEM is not available everywhere but the 1/3 second arc DEM is. It seems that the 1/3 second is not really useable for trails/old roads/etc, and that 1 meter is really the only Lidar we are interested in. Is that correct or could I be missing a setting/export option?
