They should range from 700 feet to 1,000 feet.</SPAN><BR /><BR /><SPAN>I am using a stream feature class that has the fields "FromElev" and "ToElev" that I have populated using elevations from the original DEM.</SPAN><BR /><BR /><SPAN>I have only found one thread about this and the fix was to use a geodatabase, not a shapefile. I have never used a shapefile for this.
