That's no big deal, if the distances you're measuring are small
compared to the radius of the earth (which seems pretty likely for
line-of-sight laser ranging to positions on the surface of the earth).
Just multiply the dx and dy formulas I gave you by
cos(elevation*!DTOR). Of course, you have to add
distance*sin(elevation*!DTOR) to the altitude of your known site to get
the altitude of the other site.
