Lidar to TIN

I downloaded some Digital Elevation Models from TNRIS and I need to create a TIN from the data. Can anyone help me with this process?

  • Jason,  I can understand why it's confusing.  You actually need to go through the "import" process two times.  Once for the las to pointcloud (keyin: pointcloud dialog open) and another for the pointcloud to terrain.  What coordinate system is the las in?   You can try without the coordinate system in the import dialog... let that stay default for now and verify location of the TIN later.  You may want to change the point density of the pointcloud at this point before creating a terrain from it.  Once your pod file is made from the import of the las, go to terrain tools and import from point cloud (the 4th icon on the first  row Terrain tools ...one that looks like a cloud icon as shown by @mark's comment above) Once that is imported, you can use the context sensitive menu by selecting the surface terrain in the view window and export as Geopak TIN.
