Creating DEM for a .xyz export triangulates outside DEM bounds
It might be just procedural but here is what I'm trying to do and what I see happening.
I have a .bil file that I need to transform from LatLong in vertical meters to a State Plane in vertical feet and then export as a .xyz
I open the .bil, then in Configuration set the new coordsys.
This doesn't change the vertical from meters to feet. The procedure I was told to fix this was to create point features, then create a new elevation model in feet, then create point features on that to export.
The elevation model triangulates across the empty data areas. Then, when creating point features again, it creates thousands (100s of thousands :-) of unneeded points and therefore bloats the resulting .xyz export.
Is there a better way to approach this?
Here is a video of what I'm doing http://screencast.com/t/X9vd7bXwMg
Let me know if I can provide more info.
Thanks in advance for any help.
