dem data spikes

[aldred2]

Thanks. In the end I went through 3DEM using *.ter, not DEM. That seemed to mess up my sea level (that was perfect with the DEM), but didn't give me spikes. Ideally, there'd be a utility for me to go in and edit the DEM data, identify the spikes and get rid of them. Then again, there also seemed to be problems with incorrect elevation values with DEM through 3DEM, so maybe I'm better off with a different route. I don't have Polytrans unfortunately.

thanks
