Re: [Qgis-user] problem with cartographic label placement

[Andreas Neumann via QGIS-User]

Hi Uwe,

I just tried it. 'B,BR' worked for me. Just don't use quotes before and
after the separator.

Greetings,
Andreas

[Qgis-user] problem with cartographic label placement

[Uwe via QGIS-User]

Hello list,

 

for cartographic label placement, according to the help docs it should be
possible to define position priorities in a ranking.

But when I open the editor and enter a comma separated list like:

 

'B' , 'BR'

 

I get an error message. Entering just one value it works. But that doesn't
make sense because I need at least two values to let the label move when it
collides with a feature.

What can be wrong with my input? I use 3.28.

 

Thanks a lot for help.

 

Uwe

Dennis, do you mean your object of interest is a MULTIPOLYGON?  Because if
so, your bounding box, and therefore your spatial index, is going to bound
the entire polygon, and that's going to limit any kind of efficiency as you
zoom in.

You might consider splitting your MULTIPOLYGON into POLYGONs.  That way
each POLYGON will have its own bounding box and therefore your spatial
indexing scheme will have the chance to be more efficient.  But of course
you have to watch out for polygons like the Mississippi River.

This article might help
https://www.alibabacloud.com/blog/postgresql-how-to-optimize-spatial-index-based-query-performance-for-multipolygon-data_597324

I agree with Richard; PostGIS provides nice geometry indexing.  Probably
other database managers do as well.

I'm not certain that I follow what you are doing precisely, but one kind of
architecture would be to have your database within PostgreSQL / PostGIS,
being accessed by QGIS server and delivered to your clients that way.

The QGIS server guide is here
https://docs.qgis.org/3.22/en/docs/server_manual/index.html

The PostGIS manual is here https://postgis.net/documentation/

There are many, many resources available to learn PostGIS.  From personal
experience I know this is a good one

I don't know what it is called.  We currently use google maps to display, but 
we are loading everything onto maps, so it works as long as its not big.  We 
need something that can auto scale depending on the map view..

But looking to only display what is on the customer screen.  We should never 
get the 50 meg poly..

Re: [Qgis-user] Service Ticket #353317 - GIS work on VPN - Archae-Aus

[Andreas Neumann via QGIS-User]

Hi Virag,

This depends a bit on the data sources used in the project (files vs 
databases vs web services).


But in general, VPN connections with a high latency are not recommended 
and will result in really bad user experience. QGIS does a lot if I/O 
when opening layers and working with databases. A low latency in your 
network is crucial for having a good user experience.


If you run into such issues, I recommend using a remote desktop solution 
(such as RDP, Citrix) and make sure that the QGIS desktop application 
runs in the same local network like your database / data source - so 
that the latency between QGIS desktop and your data sources is 
minimized.


BTW: other GIS will have the same issue. For example ESRI ArcGIS desktop 
wouldn't perform well in such a situation.


Greetings,

Andreas

VPN shouldn't affect speed other if the QGIS inside VPN is attaching some
remote folder included in the QGIS browser... try to remove that folder
from the browser scan.
