Thanks much for this information. I've got a start on rebuilding the
UTM page to show parameters of all projections. I've got the usual
formatting hangups (currently can't figure out how to clear the page
if you want to look at another projection), but it is moving along.
I agree that we sh
Thanks much Glynn. This is helpful. There is no urgency on the
parameters without descriptions right now since nothing seems to use
these, but we can't use them in the future without some kind of
description to parse.

u, could you explain that more? inner UTM terms may be interesting
on the summary page, but beyond that the user just cares about "zone 12
North" + datum choice(s). For UTM the projection will

ah, right (eg r.info). so UTM must be a special case.

A pure projection is a mathematical formula specifying how
geographic space bends. SP and UTM are a table of contents for
which EPSG code to use.
