Re: [Geographiclib-users] Projecting ECEF into UTM

[Ben A. <ad...@in...>]

Charles,

brilliant! Thank you for these quick and helpful answers! I tried 
implementing them, here's my problems:

Why do the GeographicLib::UTMUPS::Forward/Reverse method not use const 
for input parameters? That breaks a lot of my code. Of course I could 
make relevant members mutable or use const_cast, but that seems weird.

Now that I have the EPSG code, I need to get the WKT. Grepping for wkt 
in the GeographicLib sources didn't yield any results, so I guess I need 
to search and extract the relevant line from EPSG2WKT.TXT (google-hit at 
geospatialpython) myself?

Comparing that file with the WKT from http://spatialreference.org, the 
text file seems to be missing the AXIS-entries. Also, of course, the 
height information is missing. Maybe it's out of GeographicLib's scope, 
but I wonder how exactly the WKT for e.g. UTM 11N with height above the 
WGS84 ellipsoid in meters should look like.

Why does GeographicLib::UTMUPS::EncodeEPSG(11, true) return 32610? 
Shouldn't it be 32611 (http://spatialreference.org/ref/epsg/32611/)?

Thanks again!
Ben
