Change the DEM display.  This will be most useful with the lidar DSM and the MERIT, and looking at a relatively small area at 1:1 map view

Close all the DEMs except the MERIT.

Open image, and pick the Landsat 8 scene subset that is in c:\mapdata\tm8_atlas.  You can select any of the TIF files; the program will recognize and open all the bands.
