Using GDAL 3 with spherical mercator

Hi,

congrats on the release of osgEarth 3.1.

I haven't had the chance to test the new version, but i've read the release notes and found the hint about the spherical mercator with GDAL3. i tried to fix the spherical mercator in the following commit:

https://github.com/aroth-fastprotect/osgearth/commit/f815fdf5ac93715d5c153c8ad2b92e0ebef46695

Basically instead of using "+proj=merc" you need to use "+proj=webmerc". This results in GDAL to create a SRS with equal major and minor axis.

Keep up the good work!

Regards,
Andreas

Hi Andreas,
You're right. I was sure I tried this and it didn't work - but it does. I will get your fix into the 3.1 branch. Thanks!
