Get resolution of elevation dted data


I am loading up elevation using various DTED files. I was wondering, does osgEarth provide a way to query what the resolution/density of the elevation layer is?

If I remember correctly, DTED0 has a density of 900m, DTED1 has 90m, and DTED2 has 30m.Is there a way to tell what the density is on certain tiles within the layer, or tell which kind of DTED file is loaded into the layer?
