HI all
The question when i get round to it has probably been asked and answered
before,
but can somebody save me a small library-search, please.
Mostly for my own amusement, but also because i have often wondered what
COG grid cell the footbridge across War(r)ina Inlet lies in,
I have been
trying to overlay the COG grid system (latitude and longitude) onto a Gregory's
2004 Canberra Street Directory (eastings and northings)
To do this i need to know
the reference co-ordinate system (Mapping System) used for each.
Gregory's is almost
certainly AMG66 ACTSTATE or possibly AMG84 Zone55.
It doesn't matter much
since the difference in an easting (or northing) is less than 2
metres.
My question is what is the
underlying Mapping System used for the COG grid ?
roger curnow.
