[Qgis-user] Raster calculator questions

[Chris House]

When using raster calculator in QGIS 3 I  have to create a new raster first to 
serve as the output. Is the intent of this to overwrite a input raster (I 
haven't tried this) or something else? I'm confused by this. 

 

Secondly when I specify a CRS in raster calculator I get "insufficient memory 
for this operation" error.  Using the default output CRS works. This usually 
requires me to add a reprojection step on the output raster.

 

Windows 10

Samsung SSD

AMD 8 core processor

16 GB RAM

NVIDIA Graphics Card 2GB RAM

 

Thanks

--Chris

Re: [Qgis-user] mac qgis3 binary errors

[Adam Dershowitz]

Ooops.  My mistake.  I didn’t read your instructions carefully enough.  After 
reinstalling, with pip, I then had not reinstalled qgis.  I did that, and now 
it does open correctly.

Thanks much for the help!

Re: [Qgis-user] mac qgis3 binary errors

[William Kyngesburye]

Also reinstall QGIS.  That will get all the rest of the python bits QGIS needs.

Re: [Qgis-user] mac qgis3 binary errors

[Adam Dershowitz]

I think that is the problem.  Towards the bottom of my original email I 
mentioned that I had only installed python3.6 (from the official source) but 
not the other options (GUI, command line, pip etc).  I had not realized that 
any of those were necessary.  I’ll try to reinstall python with pip, then 
reinstall gdal, and see how that goes….

Interesting.  Now, instead of 4 different error boxes on startup, I just get 
two:

Couldn't load plugin 'processing' 
ModuleNotFoundError: No module named 'psycopg2' 
and 

Couldn't load plugin 'MetaSearch' due to an error when calling its 
classFactory() method 
ModuleNotFoundError: No module named 'owslib'

Perhaps there is some other piece missing as well?  Do either of those core 
plugins require the python UNIX command line, or GUI stuff?  

So, making some progress…

thanks,

--Adam

Re: [Qgis-user] mac qgis3 binary errors

[William Kyngesburye]

That's strange.  There should be many folders there, for osgeo and all the 
other stuff QGIS needs.

Another possibility is you are missing pip.  it's an install option for python 
3, normally installed by default but maybe you turned it off?

You can check in a Terminal with

type pip3

If found, the path should be in 
/library/frameworks/python.framework/versions/3.6.  If not found, try 
reinstalling python 3 and use the default install, then reinstall GDAL and QGIS.

And, just checking, but how did you install Python 3?  The "official" package 
from python.org?

William has been extremely helpful (in the past many times on non-qgis stuff, 
as well as right now).  I had no intention of any offense, I just was trying to 
give a quick practical answer.  

If anything more was read into it, please do accept my apology.  I greatly 
appreciate the qgis project, and the free effort that goes into it.  I’ve seen 
many inappropriate responses on open source project emails, and I had no 
intention of adding to that problem.

William, thank you much for the assistance.

—Adam

Ok, sorry then. To me it sounds like: 'Tsjee, thanks for nothing'. But
maybe a cultural/language thing... even though dutch people are infamous
in sensitive handling of feelings/cultural differences :-)

Hi Adam,

Please stay friendly to people who try to solve your(!) problems in
their free time, even if it gets frustrated sometimes.

William had a 'response time' of 3 minutes. Try that with commercial
help desks :-)

Re: [Qgis-user] mac qgis3 binary errors

[William Kyngesburye]

Is there an "osgeo" folder in 
/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages ?

Thanks.
I just tried to install gdal, then reran qgis3 and got the same errors, so that 
didn’t help.

Re: [Qgis-user] mac qgis3 binary errors

[William Kyngesburye]

You must make sure that that python 3 is installed before installing GDAL 
Complete.  Reinstall GDAL and it should work.

[Qgis-user] mac qgis3 binary errors

[Adam Dershowitz]

I downloaded the mac qgis3 binary.  I also installed the official python 3.6.  
Whenever I first launch qgis I get a series of errors that pop up and look like 
this:

Couldn't load plugin 'FreehandRasterGeoreferencer' due to an error when calling 
its classFactory() method 
ModuleNotFoundError: No module named 'osgeo'

Traceback (most recent call last):

ModuleNotFoundError: No module named 'psycopg2' 
Couldn't load plugin 'MetaSearch' due to an error when calling its

ModuleNotFoundError: No module named 'owslib' 
 
Is there something that is missing.  I had tried to use the macports version of 
qgis3, and didn’t see these errors (although I did get other errors).  Then, 
once I close each dialog box, it opens and works.  But, the vector and raster 
menus don’t show many entries (while they did with the macports version). 
When I installed python 3.6, I only installed the framework.  I didn’t include 
the optional installs such as:  GUI applications, command line tools, 
documentation, shell profile updater, or pip.Could that be causing the 
problem?  If not, is there something else about plugins that I have to fix?

So the point layer has Z coordinates with elevation? What method of
altitude clamping have you chosen for the point layer's 3d renderer?
It seems like you are using absolute clamping... the other two methods
respect the vertical scale.

[Qgis-user] Error while processing "servicearea"

[Jean-Baptiste Desbas]

Hello,

I want to use the serviceareafromlayer alg in a python script, but it give
me an error :

Traceback (most recent call last):
File
"C:/PROGRA~1/QGIS3~1.0/apps/qgis/./python/plugins\processing\algs\qgis\ServiceAreaFromLayer.py",
line 264, in processAlgorithm
fields, QgsWkbTypes.MultiLineString, network.sourceCrs())
Exception: unknown

I can successfuly lunch that alg with the same input layer from the GUI, so
what's wrong with my code ?

Here is the code : http://paste.debian.net/1023040/

Thanks,

Hi users, hi developers,

I am pleasure to introduce you a new suite to publish QGIS
projects on web by QGIS-Server  that we developed in past 2-3
years at GIS3W

​This project sounds interesting. Some questions:
1) this webgis should run under django ​system?
The system is a CLIENT-SEVER system based on a API REST comunication, 
webgis client is indipendent from admin server.
A the moment webgis layout page is served from a django view, but there 
aren't problem if base layout page is outside django system.

2) is it extensible (i.e. can I add custom buttons, actions, etc...)?
Yes is possible to add custom elements in programming way, as I wrote 
webgis client built with vue.js (https://vuejs.org/) with reactive logic.
3) there's a tile caching system. Does it solve the usual problems 
with labels?
Inside repository you find a module for chaching: 
https://github.com/g3w-suite/g3w-admin-caching
Is a django module that user Tilestache for caching single layer of a 
QGIS Project.
Is very simple and a the moment solve labels problems with tilestache 
capabilities.
