Question:
Do you know why some **projected** coordinate reference systems use
axis order Northing-Easting?
Is that a historical reason?
If I remember correctly, Roger Lott from EPSG told me that it was
reflecting the local convention of the country that defined the
projected CRS. The abbreviation as well, even if "X" is sometime used
for Northing (for example), it, this is because the country that defined
the projected CRS does that way.
In some way, the EPSG database can be seen as not only a database of CRS
and coordinate transformations relating them, but also a database of the
local conventions for each country. In some way, the CRS contains
localization data.
