[OSGeo Africa] CRS in use in South Africa

[Heidi Van Deventer]

Coincidently I stumbled upon this article after you sent this
communication earlier this week:

Waywell T 2009 The effect of various map projections on surface area.
PositionIT July: 49 - 55

https://www.ee.co.za/wp-content/uploads/legacy/PositionIT%202009/VisT-The-effect-of-various.pdf

Kind regards,
Heidi

Hi Zoltan

we use the Albers Equal Area conical projection for South Africa with
the central meridian at 25°E, parallels 24°S and 33° S, spheroid and
datum = WGS84 for calculating the extent of ecosystems at a national
scale in the National Biodiversity Assessment for 2018.

Kind regards,
Heidi

I want to set an informal assignment for my candidates, to help them
recognise common CRSes used in South Africa (South, not Southern).
Off the top of my head I can think of:
	●  Non projected Lat Long
	●  Lo system (North and/or South facing) projected from either
Clarke 1880 [if very old] or WGS84
	●  UTM33-36S
Are there any others in common use? 

If so, by whom?
Thanks and keep well,
Zoltan
