Hi,

and South
If +ve E/N then try EPSG:102567
I forget which of the remaining 2 (2053 and 102487) Lo29 codes are left
or right handed, but you only have these 3 to try.

I have a SHP file with 28000 polygons.

It's part of a much longer python script doing a bunch of other stuff,
so to now change the flow to incorporate postgis is not really an option.

Create the rectangle AT the POI.
You have not said what your environment is (Python or GUI), but you can
try this from the Processing Toolbox:
Rectangles, ovals, diamonds

Hi,
In Symbol Setting you can specify an attribute field to set the *size*
of the symbol. (click right-most icon [yellow in this image])
Maybe fiddle with this to see if you can achieve what you need.
Good luck and kind regards,

Hi Johannes,
How long is a piece of string and what strength is required, for what
you want to tie up with it? 🙂
I buy equipment for my work and keep it 'going' for >5 years before
replacing it, so I have no issue with throwing lots of money at it.
