[Qgis-user] (no subject)

[takacsviki]

Hi all!   Please help me!! I installed QGIS 3.16. When trying to add a VMS 
layer, it returns me the following message:    Nie powiodło się pobranie 
Capabilities:Pobieranie "capabilities" nie powiodło się: Dostęp do 
sieci wyłączony. =   download CApabilities was unsuccessful, the network access 
is switched off.    Should I configure somewhere network connection? What to do 
and how? Previously I have used several versions of QGIS but never had similar 
problems.    Thanks for the help!   Viktoria

I think the best approach will greatly depend on your input data 
structure and situation, but I should think it certainly is possible.


In the processing toolbox, there is a GRASS tool called 
v.voronoi.skeleton which is pretty effective at producing single 
centerlines from polygons. If what you want is not achievable with a 
single tool, the modeler will allow you to chain processing steps to 
achieve that outcome, likely in a much more effective manner than in 
the article you linked to. There may also be community built 
processing models available on GitHub or GIS stack exchange which 
might already do this for you. We are hoping to get more solutions on 
the https://plugins.qgis.org/models/ 
 platform so that this type of 
content is more discoverable in future.


I hope that's at least enough to help you get started.

Hi there,

I think it may be a bit unclear exactly what your objective is.
Perhaps attaching an illustration of some sort would help the
community better understand the problem so that we can assist
with a solution.

Hello colleagues,

I need to generate in QGIS street axes from a block face and
that these axes cross for two meters.

It's possible?

[Qgis-user] How to change polygon size in the symbology

[krishna Ayyala]

Hello,
I have a Polygons layer with about 25 features of different sizes. How to
increase its size in the symbology such that the size of the 25 polygons
increase proportionally?

Regards.

Re: [Qgis-user] How to change polygon size in the symbology

[Hugh Kelley]

Hi Krishna, you can either use the buffer tool under "vector" >>
"geoprocessing tools" to permanently create larger polygons or you can use
the geometry generator option in the symbology settings to generate and
then symbolize buffers around the polygons on the fly.

Re: [Qgis-user] LAStools on Mac Catalina --- LAS -> LAZ

[Maria Shinoto]

Hi, 

this is an answer to myself for anybody interested. 

Three possible solutions I thought of: 

(1) QGIS -- LAStools seem to not work any more on Macs above version 3.14.

(2) wine -- this would have been an elegant solution in the mac Terminal: 'wine 
lastoolscommand filename' -- But unfortunately, wine does not work with Mac OS 
10.15 and above any more. 

(3) Virtual Machine or Parallels Desktop with Command Line Interface -- 
horrible since I absolutely do not know Windows, but the CLI was fine, so I 
opened the CLI at the folder with the .las files and the LAStools.exe file I 
needed (laszip.exe in particular; all in the same folder); and that worked 
really well. I was afraid of the reaction of the Virtual Machine on the large 
files, but no problem. 

So (3) was the way to go. I only hope that wine will return to the Mac...

Best and thank Nicolas for your support, 
Maria
