[QGIS-Developer] USNG Coordinate System

[Joshua Quesenberry]

All,

 

Is there some way to plot USNG coordinates in QGIS? And if not, when will
support for that be added?

 

Thanks,

 

Josh Q

Re: [QGIS-Developer] Processing R scripts - TypeError: cannot concatenate 'str' and 'NoneType' objects

[Anita Graser]

Maybe a fix ...

​Not sure if it breaks anything else, but if I add

​elif isinstance(out, OutputHTML):
pass

before the offending

elif out.name != RAlgorithm.R_OUTPUT_VALUES:
commands.append('cat("##' + out.name + '",file="' +
outputDataFile + '",sep="\n",append=TRUE)')
commands.append('cat(' + out.name + ',file="' +
outputDataFile + '",sep="\n",append=TRUE)')

Then the HTML output is created and visible in the results viewer and there
is no error.

I'm not sure what the problematic lines were supposed to do anyway ...

Best wishes,
Anita

Can anyone tell me what was the last Processing version where R scripts did
work?

[QGIS-Developer] Split features tool behavior

[Andreas Wicht]

Hi all,

I have a question regarding the behavior of the "split features" tool
when it comes to multipart polygons.
For that I created a small example (see split_features_1.png).

The polygon "1" is a multipart polygon as shown in the screenshot.
Let's say a user wants to split the lower polygon into two in order to
merge one part to the polygon "3" (here the workaround would be the
usage of the reshape features tool) or to create an entirely new
feature. (see split_features_2.png).

The expected result would be a the separated polygon (here on the
right) and the rest of the polygon including the part on the top. 1
Multipart Polygon and 1 Polygon.

The QGIS result is three separate Polygons. This behavior can be
dangerous when editing complex layers.
If furthermore attributes are being changed and aggregations happen
potential errors or unexpected results for a user are imminent.

Other GIS produce the expected output of 1 Multipart Polygon and 1 Polygon.

What is the specific intention behind this behavior as it seems not
quite intuitive?

Cheers

Re: [QGIS-Developer] [Qgis-developer] FOSS4G Boston QGIS presentation?

[Larry Shaffer]

Hi,

Apologies for the delay in my reply. The talk was accepted for FOSS4G 2017
Boston, and Kurt / myself will be co-presenting.

The "State of QGIS" talk abstract is attached. I will be bringing this
topic up with the community to gather contributor feedback on overall
content and direction, since the talk should represent community viewpoints
and cover topics the community thinks it should.

Regards,
