DEM display units

Question

Hello, im facing a problem on my DEM i created recently. Well, i created 2 shp files by digitizing contours and elevation points using a topographic map of my study area and a 3rd polygon shp file as boundary type. Then using 3D Analyst Tools -> Raster Interpolation -> Topo to Raster created the DEM. I changed the sympology but the problem is that the elevation value is displayed in pixels, i mean when i identify somewhere in the DEM data i get a pixel value... I want to change this so i can change the symbology so values are displayed in meters not in pixels.. How can i do this?  ( data frame units are in meteres but this has no effect on DEM)

Jim,

If the elevation values you attributed to your contours and points were in units of meters, then the result of Topo to Raster is a raster with units of meters.  When you use Identify and it returns a value like 2500 it means that pixel is 2500 meters.

Best,
Eric

May be you are not using the correct reference level, you leave some tutorials ArcGIS ArcScene: Tutorial de ArcGis.

Also check out these tutorials Spatial Analyst where you also find a tutorial ArcScene
