[Qgis-user] Fuller Dymaxion Projection Imagery & Digital Elevation Models Largish Scale

[Keith Winston]

I am a proto-beginner with QGIS. I'm a mid-novice with GIS & mapping.
I am hoping to produce a large-scale world Fuller/Dymaxion projection with
both/either satellite imagery & digital elevation data and state/national
boundaries (maybe cities), intended to be printed out at something like
10,000 x 20,000 pixels (around 2m x 4m or so, in color).
I would like to learn how to do this, I wonder if anyone could help sketch
out a roadmap, or otherwise help me get started? Just a quick outline of
the kinds of things I'm going to need to learn to do? I've only played with
QGIS a bit, and I'm going to be doing this in my (very little) spare time,
so it may take months, but I generally find I learn things best when I have
a project to work on. However. at the beginning I don't even know what I
need to learn first.
If there are particularly good/applicable tutorials, or anything else you
can point me towards, I'd be very grateful. I realize I may be overreaching
for a beginner, that's ok. Thanks for any help!

[Qgis-user] Splitting a Line

[Bob Bruce]

I have a line of a hiking trail in Austria that takes me up to the hutte and
back down. I want to edit it so that I break it up at the middle (where it
doubles back) and then delete half of it. How do I do that in QGIS? I have
tried the split features tools and they do not do what I want.

 

Thanks in advance,

Bob Bruce

Re: [Qgis-user] Vertex tool not working on lines when style with 'attribute' assigned

[Nicolas Cadieux]

Hi,

Open the field calculator.  By default, you will have « create a new field ».  
Select « create virtual field » and use the attribute there. The virtual will 
be updated on the fly and is part of the project file.  If you export the file, 
it will be saved as a true field in the Shape file (or what ever format you are 
using).

Re: [Qgis-user] Vertex tool not working on lines when style with 'attribute' assigned

[Peter Cornelissen]

Hi

I have reported it as a bug, but as yet no resolution or acknowledgement that 
it is a bug. I was offered possible solutions but in the end it was not really 
answering the problem I have and since then it is just there as an open issue.

I'm not really at a level to be quite sure what you mean by using a 'virtual' 
field, could you please explain? The attribute method I am using was a solution 
given to me by someone else and as I say it worked fine when first used in 
version 2.8.

Hi,

This looks like a good bug report! I would do one.  Have you tried making a 
virtual field with the attributes?  This way, you can query two fields and not 
an attribute and a field. The end result would be the same but perhaps, without

Has anyone else come across this?

Personally I think this is a bug or possibly something wrong with my 
installation, but I've not had any confirmation from the QGIS team.

If I have a styled line or polygon and use the 'attribute' expression in the 
filter, then once the shapefile has been saved, closed and then re-opened, then 
the vertex editor does not work and I cannot edit any of the lines or polygons 
in the shapefile and the only way I can is to open the same shapefile without a 
style of with one not using attribute in the filter. I use the same shapefile 
numerous times and use the layer name to  display specific lines as relevant to

starts Plan1801. An example of the style is: attribute($currentfeature, 
left(@layer_name,8)) = 'Y' AND Type = 'Chalk'), so if a record in the shapefile 
table has a 'Y' in the Plan1801 column and 'Chalk' in the type column it will 
display as that style. If I change the style to Plan1801 ='Y' AND Type = 
'Chalk' the vertex editor works fine.

There maybe another way around this, but there are approx. 20 different styles 
for the lines and a similar number for the polygons used in each layer and 
getting on for 30 layers (and growing) using it so I do not want to have create 
dedicated styles for each layer or have a separate shapefile for each layer. If 
there is, I have not as yet found one.

Any help would be appreciated.

I am now using version 3.6.3, but the problem has been there at least since 
3.6.0, possibly earlier (not there in the old node editor in 2.8, but I know 
that was a completely different beast).

Re: [Qgis-user] Fix Geometries

[Nicolas Cadieux]

Bonjour Alain,

I read the document and it's useful.   IMHO, this should be included in 
the QGIS documentation in the future.  Under QGIS 3.6.2, I used the 
plugin but I had to fix one problem at a time because of stability 
issues.  I did not make a bug report because one was already active.  I 
may be able to give you access to my shape file if you are interested in 
trouble shooting.  I would need to ask first because I do not own this 
database but I am confident I could obtain permission.  Send me a 
private email if you need more info.


Bonne journée!

Hi Finbar,
One other solution would be to use a double buffer, as in a positive 
buffer something like 0.001, followed by a negative buffer of -0.001.
The issue you are facing is common, as most flood polygons are 
derived from raster's and you can get a lot of self-intersections. 
The double buffer is in my experience the handiest method of solving 
the issue. Also by using such a small buffer, even a single buffer, 
will make little difference, to a house being in or out of a flood 
zone, when taking into account the, resolutions of the polygon datasets.

Hope this helps,

Regards,

Richard.

Hi,

The Geometry Checker plugin will add a the 'Check Geometries' option 
in the vector menu.  It is very unstable with the current version of 
QGIS. If you get it to run, it should solve most problems.  I get it 
to run when I only select one test at a time.


The most predictable tool is the vector/geometry tools/Check validity 
using the 'QGIS' Method (not GEOS).  That should fix your file.  
There is a 'remove duplicate vertices' and 'delete duplicate 
geometries' in processing.  Your problem could also be caused by a 
module not working with multipart objects.  Go to vector/Geometry 
tools/Multiparts to singleparts.


If your lines don't touch,   try the 'snap Geometries to layer ' in 
processing.

Hi Finnbar,

What plugin are you talking about and what QGIS version do you use?
You have a number of tools to check geometries. Try "Topology checker"
or "Geometry checker" to see where the problems are (invalid
geometries). Geometry checker is also able to fix some issues. Maybe
thats the one you use.

Anotehr option is GRASS GIS. Have you ever worked wit GRASS GIS? You
can create a GRASS database and import your polygons. GRASS GIS uses a
topolgical data model and is quite powerful in establishing a desent
data model with snapping options and clean functions. You can also try
GRASS tools from the processing framework like build polygons or clean.

Hi All,

I have a few polygon layers where anytime I go to use them I have to
use the fix geometries plugin so that invalid geometries are fixed.

When I save the output from the fixed geometries plugin and add it in
a new project the same issues appears where I can’t use it accurately
to do a Select or Join by Location because some of the geometries are
still seen as invalid even though they have been ‘fixed’.

Is there anyway solution to this or do I have to keep using the fix
geometries plugin anytime I use the polygons for analysis?

[Qgis-user] Meeting in October 2019 in the Southeast US

[Randal Hale]

Good Morning/Afternoon QGIS Listserve - and sorry for the 
duplication/spam as I've sent this out on several other listserves and 
many of you are way outside of the SE United States.


I'm hopefully going to hold a QGIS centric meeting in the Southeastern 
US in October 2019. Right now I'm trying to piece together an interested 
group of people and hold this around the Chattanooga TN area (which 
could be Huntsville, Chattanooga, Knoxville, Asheville, etc). It will 
probably be a 1 day meeting but depending on interest we could go more. 
I've held meetings (with the help of a lot of great people) in the past 
[1] centered around FOSS4G software and they've had quite a turnout with 
topics ranging from SAGA, LIDAR, QGIS, and PostGIS.


There is a OSGEO Listserv covering the SE US [2] and I'm preparing to 
pepper the list with information and put up a central location for 
information. I'm open to suggestions for a location. I'm hoping to nail 
down a date and location shortly so if you are so inclined join the 
listserve below and we can discuss. I'm open to sponsors and whatever 
else we might need. Usually the biggest expense for these meetings is 
food and snacks. Depending on interest we may need more than that.


Anyway - hopefully those of us in the Southeast US can get together and 
talk about QGIS.

[Qgis-user] Vertex tool not working on lines when style with 'attribute' assigned

[Peter Cornelissen]

Has anyone else come across this?

Personally I think this is a bug or possibly something wrong with my 
installation, but I've not had any confirmation from the QGIS team.

If I have a styled line or polygon and use the 'attribute' expression in the 
filter, then once the shapefile has been saved, closed and then re-opened, then 
the vertex editor does not work and I cannot edit any of the lines or polygons 
in the shapefile and the only way I can is to open the same shapefile without a 
style of with one not using attribute in the filter. I use the same shapefile 
numerous times and use the layer name to  display specific lines as relevant to 
that layer. E.g. the table has a field called Plan1801, so the layer name 
starts Plan1801. An example of the style is: attribute($currentfeature, 
left(@layer_name,8)) = 'Y' AND Type = 'Chalk'), so if a record in the shapefile 
table has a 'Y' in the Plan1801 column and 'Chalk' in the type column it will 
display as that style. If I change the style to Plan1801 ='Y' AND Type = 
'Chalk' the vertex editor works fine.

There maybe another way around this, but there are approx. 20 different styles 
for the lines and a similar number for the polygons used in each layer and 
getting on for 30 layers (and growing) using it so I do not want to have create 
dedicated styles for each layer or have a separate shapefile for each layer. If 
there is, I have not as yet found one.

Any help would be appreciated.

I am now using version 3.6.3, but the problem has been there at least since 
3.6.0, possibly earlier (not there in the old node editor in 2.8, but I know 
that was a completely different beast).

Re: [Qgis-user] Map Matching

[Christoph Jung]

Hi Chintan,

I had a look on the data you provided:

1. I just found the DBF-file, not the whole SHAPE, so I could not reproduce the 
problem with your data.
2. The DBF contains over 60.000 data sets, I think that is the network.
3. The screenshot you provided does not show a problem, but it looks like the 
plugin is still running (check the task manager to confirm it).

If you are using a very big network, than the plugin will slow down. Please 
read the detailed description of the plugin in the README on GitHub. In short:
The plugin hangs on the task „calculating transition probabilities“. 
Transitions are a pair of two candidates, i.e. points on the network that could 
represent trajectory points. For each transition the shortest route on the 
network will be calculated using the Dijkstra algorithm. Dijkstra steps through 
all nodes of the network to find the nearest  parent node. If you are using a 
big network with a lot of nodes, this task needs some time. Especially if you 
have a lot of candidates and transitions (because of outliers, a too big 
maximum search distance or something else) and the task has to be repeated very 
often. So my advice for you is to use a spatial filter before you start the 
plugin:

1. create a line from your trajectory (e.g. using points to line)
2. create a buffer from the line (e.g. 500m)
3. clip the network using the buffer as clipping mask
4. run the plugin with the clipped network

I will integrate this task in the plugin in a future version. But the plugin is 
a free time project and actually I am working on another project. So the new 
version will take some time. Please try the described workaround.

Sincerely,
Christoph

Re: [Qgis-user] Rogue start menu shortcut (Fernando M. Roxo da Motta)

[Andy Harfoot]

I have also observed this 'additional shortcut' behaviour on Windows 10, 
and assumed that it had been introduced deliberately by the QGIS 
developers to allow a QGIS shortcut to be pinned to the taskbar. 
Previously if this had been attempted, the resulting shortcut would not 
restart QGIS. This problem only applied to pinning to the taskbar, 
pinning to the Start menu always worked correctly.

I had assumed (but not tested to confirm) that this was due to the 
intermediate call to a BAT file to configure paths when starting QGIS. 
The 'new' shortcut that is created on first run seems to avoid these 
problems.

Cheers,

Andy

Re: [Qgis-user] Rogue start menu shortcut

[Paul Wittle]

Hi,

It turns out that it has already been reported as a bug but I can't see how to 
upvote it or add details of my install version etc to the bug report.

See Bug report #20890

Is anyone on this group in the development groups and able to tell me the 
status of this bug report? Has it even been read and is it really not a quick 
fix? Would I be correct in thinking there needs to be a switch added to a 
function in the winToast dependency to fix it?

Thanks,
Paul

Hi,

This is nothing to do with the recently used program settings. Firstly, I don't 
have that setting enabled anyway and secondly those settings show icons at the 
top of the start menu but they don't create a physical shortcut file in the 
start menu folder structure.

This is much more likely to be a bug in the application as I'm almost 100% 
certain that it is QGIS creating the file and not Windows.

Given this is a user group I might just raise it as a bug and see if any of the 
developers have noticed it as well.

Re: [Qgis-user] Fix Geometries

[Chef de groupe]

Hi,

We published a document in early 2018 on geometry fixes.
This document should be revised, but may provide some elements.
(For example, geometry checker is now more stable under QGIS 3)

It is open for comments...
We have in our projects to produce a more user-friendly version

see : 
http://geoinformations.metier.e2.rie.gouv.fr/spip.php?page=article&id_article=3522&id_rubrique=712

Hi Finbar,
One other solution would be to use a double buffer, as in a positive buffer 
something like 0.001, followed by a negative buffer of -0.001.
The issue you are facing is common, as most flood polygons are derived from 
raster's and you can get a lot of self-intersections. The double buffer is in 
my experience the handiest method of solving the issue. Also by using such a 
small buffer, even a single buffer, will make little difference, to a house 
being in or out of a flood zone, when taking into account the, resolutions of 
the polygon datasets.
Hope this helps,

Regards,

Richard.

Hi,

The Geometry Checker plugin will add a the 'Check Geometries' option in the 
vector menu.  It is very unstable with the current version of QGIS. If you get 
it to run, it should solve most problems.  I get it to run when I only select 
one test at a time.

The most predictable tool is the vector/geometry tools/Check validity using the 
'QGIS' Method (not GEOS).  That should fix your file.  There is a 'remove 
duplicate vertices' and 'delete duplicate geometries' in processing.  Your 
problem could also be caused by a module not working with multipart objects.  
Go to vector/Geometry tools/Multiparts to singleparts.

If your lines don't touch,   try the 'snap Geometries to layer ' in processing.

Hi Finnbar,

What plugin are you talking about and what QGIS version do you use?
You have a number of tools to check geometries. Try "Topology checker"
or "Geometry checker" to see where the problems are (invalid
geometries). Geometry checker is also able to fix some issues. Maybe
thats the one you use.

Anotehr option is GRASS GIS. Have you ever worked wit GRASS GIS? You
can create a GRASS database and import your polygons. GRASS GIS uses a
topolgical data model and is quite powerful in establishing a desent
data model with snapping options and clean functions. You can also try
GRASS tools from the processing framework like build polygons or clean.

Hi All,

I have a few polygon layers where anytime I go to use them I have to
use the fix geometries plugin so that invalid geometries are fixed.

When I save the output from the fixed geometries plugin and add it in
a new project the same issues appears where I can’t use it accurately
to do a Select or Join by Location because some of the geometries are
still seen as invalid even though they have been ‘fixed’.

Is there anyway solution to this or do I have to keep using the fix
geometries plugin anytime I use the polygons for analysis?
