<p>Hi QGIS Users,<br>
</p>
<p>I can't find these in my QGIS 3.4. And I see that Proj4 is still
on version 4.93, but the latest seems to be 5.2.</p>
<p>But what I also noticed is that Proj4 changed the way it converts
from/to Hartebeesthoek94 (15 to 31) from version 4.7 to vers. 4.9:
Using proj4 4.7 to convert one had to turn around E-W and N-S,
w.o.w. X = -X and Y = -Y and then convert. From vers. 4.9 this was
not necessary any longer so I think the calculations in QGIS
should be sorted out (it is actually a bug and that is why
everything is upside down and right=left). That would also mean
that we would not need the ZANGI:ZANGI projections any longer but
just use the built-in Hartebeesthoek94 ones.</p>
<p>For what it's worth!</p>

QGIS users,
<br>
<br>
I noticed last week that these CRSs have appeared in QGIS under
Project Coordinate Systems > Transverse Mercator:
<br>
<br>
EPSG:102480 Hartebeesthoek94_Lo15
<br>
EPSG:102481 Hartebeesthoek94_Lo17
<br>
EPSG:102482 Hartebeesthoek94_Lo19
<br>
EPSG:102483 Hartebeesthoek94_Lo21
<br>
EPSG:102484 Hartebeesthoek94_Lo23
<br>
EPSG:102485 Hartebeesthoek94_Lo25
<br>
EPSG:102486 Hartebeesthoek94_Lo27
<br>
EPSG:102487 Hartebeesthoek94_Lo29
<br>
EPSG:102488 Hartebeesthoek94_Lo31
<br>
EPSG:102489 Hartebeesthoek94_Lo33
<br>
EPSG:102562 Hartebeesthoek94_Lo19_(E-N)
<br>
EPSG:102563 Hartebeesthoek94_Lo21_(E-N)
<br>
EPSG:102564 Hartebeesthoek94_Lo23_(E-N)
<br>
EPSG:102565 Hartebeesthoek94_Lo25_(E-N)
<br>
EPSG:102566 Hartebeesthoek94_Lo27_(E-N)
<br>
EPSG:102567 Hartebeesthoek94_Lo29_(E-N)
<br>
EPSG:102568 Hartebeesthoek94_Lo31_(E-N)
<br>
<br>
Anyone know anything about them? Are these now the official South
African CRSs in the EPSG database? If so, where are L015_(E-N),
L017_(E-N) and L033_(E-N)?
<br>
<br>
With these new additions, there are now a few versions of the
South African CRSs in the QGIS CRS database (e.g. EPSG 2046 to
EPSG 2055 as well as ZANGI:HBKNO15 to ZANGI:HBK033) so I guess
things need to be cleaned up.
<br>
<br>
Regards, Frank.
