TransDEM Forum

Hi,
the LIDAR dem files are presenting problems when trying to create 3D UTM tiles. The first tile is OK but the following tiles are without the IM files and runs for hours.
The LIDAR files have points every 2m
The 2D tiles are ok

Please ignore previous comment about 3d LIDAR tiles. I didn't appreciate that the generation of the tiles involved 2 passes and that the trainz importer , on the second pass, takes hours to generate the complete tile.
