You can use DEM shading to highlight narrow elevation ranges, but the underlying data is stored as integer meters, so you're only going to get 3' steps. Depending on the location, it may not truly be accurate to 1 meter of precision, anyway.

I think so. You can use the cursor elevation shown at the top right (or the center elevation, if you set that via the config menu) to see what the right increments are, ie which numbers correspond to whole meters.
