LL "projection"

[mike camann]

I'd like to chime in my endorsement of Jerry Evendon's recent "windmill
tilt": latitude-longitude is a coordinate system for referencing
locations on a sphere, NOT a projection.  This aspect of GRASS caused
me no end of confusion, and I consider it a fundamental bug, a
conceptual bug, if you will, that confuses two entirely distinct
concepts.  It is, I expect, an artifact of GRASS's having been
developed primarily for Army use at relatively local spatial scales,
e.g. a few USGS 7.5 minute quads.
