Re: Alternate Network Install Option

When I try to select an alternate install location there is no option using
the express install and using the advanced install does not 
 download all the files. I have created a new folder called
>C:/PgmFiles>QGIS and attempted to install it there.
Anyone have any suggestions?
Regards Grant

Is there a way to install the OSGeo4W installer into another folder other
than the c: drive root directory? Installing into the C: drive root
directory causes problems in managed IT systems.

Hi Grant,

yes, you can choose a different installation location during the
installation process.

Cheers, Hannes

Hi there,

a friend received a DWG file which is (surprisingly) directly importable
into QGIS.
The problem is, that the CAD-guys use a very strange coordinate system.

Actually, the data should be in EPSG 25833, but somehow they managed to
scramble the x-values by adding 33 before the otherwise correct coordinates.

The imported DWG has 120 layer groups, most of them rubbish like always, but
to find out which layers are valuable, we would need to be able to display
them over aerial images beforehand!
Even if I knew a way to manually convert them one by one, I certainly would
die during the process.

Does anyone have an idea how to directly manipulate the geopackage created
during the import, e.g. with ogr commands in a bash script that loops over
the relevant tables?
This might be a solution not to destroy the otherwise usable layout created
during import.

Thankful for any insights,
Bernd

So EPSG:5650?

So now I tried the import with EPSG 5653 and this one seems to work.

I am working now with geodata for around 15 years, but the CAD scene 
never runs out of new obstacles for me.

What the f is EPSG 5653, and most importantly: Why is it it even being used?

(Fun fact: once a CAD guy told me, after me complaining about his data 
having just some local cartesian coordinates and no official CRS, that 
his software would run much slower, the higher the coordinate numbers 
were, so working with short local coordinates was his way to be able to 
work at all.
Now these other guys just add another 2 digits? Obviously trying to 
evade work!)

Did I already mention that I very much dislike CAD and its seemlingly 
not existing philosophy behind it.

Thanks for the hints!

Bernd
