If Wilbur can read HF2 then thats cool, I could convert some data for Ravs.

I am not seeing any faceting in this data tho. Cant understand where you get the idea this is from a vectored source. I think were looking at different data then. Mine all looks a lot like my pics in #9. The data is at 50m spacing so its nearly twice as good as the 90m USGS and since SRTM was 1km then its 20x as good as that. This is the best whole UK DEM source I know of tho I am sure there are localized much higher res LIDAR data around somewhere.
