Don,
Thank you for your sample code. I got it to work after seeing that -
though what is *really* frustrating is I now cannot duplicate the error
I was having. Arrggh! Oh well, It works and I should let it go. ;-)
For those who use the Radar3DCoordinateSystem:
I did a little comparring between an in-house AzRanElev-to-LatLonAlt
algorithm and the Radar3DCoordinateSystem toReference() method and found
that the latter does not account for the INDEX OF REFRACTION of the
Earth's atmosphere. For "standard atmospheric conditions" the index of
refraction is 4/3 * the Earth's Radius. This resulted in ~ 200 m
difference at a range of 100 km and a ~300 m at a range of 400 km using
an elevation angle of 0.5 degrees.
If anyone has any questions about this, I'd be happy to try to answer them.
-kevin.
