I created a massive slope raster dataset from USGS NED 1/3 arc second data, projected to NAD 83 Albers, using the slope geoprocessing tool in ArcMap 10. While I have no trouble visualizing the projected DEM or the aspect I created from the same data, the slope dataset draws as if it only contained values of 0. At scales finer than 1:63,360, it draws just fine; anything coarser, though,shows only 0 values.
Has anyone encountered this before? Is there a display or symbology setting that I need to tweak? Is this a bug? Thanks!
