[UW-GIS-L] DEM interpolation

[Kregg Philpott]

List - 
   Does anyone know how to interpolate a 30m UTM USGS dem to 10m. I
thought that LATTICERESAMPLE might do the trick, but it seems that it
will fill in a rectangle defined by input lower left and upper right
corner coordinates, instead of staying within the trapezoidal boundaries
of the original DEM (these are 7.5' DEMs - so not rectangular in UTM
space). Thanks in advance for any help.
