Well, h is a hairy issue, with all the different kinds of height.
But for lat-lon, both "geographic coordinates" and "geodetic coordinates"
would be correct, as far as I understand it.
But "geographic coordinates" is probably more common (Google gives 585 000 hits
for "geographic coordinates", and only 19 700 hits for "geodetic coordinates").
Now to my own question: is there a general term that includes both geographic
coordinates (lat-lon) and projected coordinates (easting-northing), as opposed
to pixel coordinates?
I am trying to document a method that tranforms pixel coordinates to
either projected or geographic coordinates, depending on whether the
window is presented with a map projection or just as lat-lon (all right,
Pseudo Plate Carrée).
As you see, I haven't found a snappy way to express it.
I can only think of "georeferenced coordinates", but is there a better term?
