[Proj] Is it possible to store a WGS84 / Pseudo Mercator image as a GeoTIFF?

[Noel Zinn (cc)]

Andre,

"Adopted" connotes acceptance.  Perhaps "tolerated" is closer to the truth.

Mikael,

If you're not aware of "Implications of Web Mercator and Its Use in Online 
Mapping", by Battersby, Finn, Usery and Yamamoto (Cartographica 2014), 
here's a link:

And even "tolerated" connotes too much acceptance for the US National 
Geospatial-Intelligence Agency.  See link following:

Hi Mikael,

You should probably ask "since when it is supported correctly?".

I remember that EPSG:900913 was rejected by EPSG and GIS professionals
for a long time, until it was adopted as EPSG:3857.

And there were several complaints about misalignments of abot 20km to
the North, due to the non-standard transformation Google had invented.

EPSG:3395 and EPSG:3785 were some steps on the right way.

As a reference, you can look for older versions of QGIS including GDAL
and PROJ at http://qgis.org/downloads/ back to 2010.

http://www.gisinternals.com/archive.php dates back to GDAL 1.7.3

FWtools http://fwtools.maptools.org/ might still be older.

Greetings,
André Joost
