Re: [Qgis-user] Using qgis as realtime decision support tool

2018-06-18 Thread DelazJ

Hi Jeroen (and others)

The add delimited text file tool [0] has a "watch file" option that, if i'm
not mistaken, allows to apply in QGIS changes that would be made in the csv
file in other applications such as MS Excel. So, assuming you have a table
data with your municipalities and all the related information in csv-like
format, you import it as simple table with the Add delimited text file, do
a join with the spatial data and do a symbology on whether there's a
project or no.
Then what will be needed is simply update the csv in Excel and map is
updated in QGIS.

That's the theory as I could not run a 2.18 (I guess this is what you use)
to check if it works. Doing it in 3.1 fails: I can see the change in the
imported table but no repercution on the joined field nor the map (Bug?).
However 3.x adds new and powerful (but not yet documented) features in the
join table such as "Dynamic form" which perfectly triggers maps repaint
when the csv is changed outside QGIS.

If instead of csv, you want xls or xlsx there's a "spreadsheets" plugin
that allows to esily use those formats in QGIS but I can't tell you if it
has all the features.

About the statistics, one can also use virtual layer [1] and do a query
with aggregates. But having a Yes/No field in the table on which you
perform stats should return what you are looking for I think.

Re: [Qgis-user] Using qgis as realtime decision support tool

Re-opening the project does indeed update the map.
And the statistics toolbar does provide useful information, but just for 1 
column at a time.

Okay, learned some new things, but it is not yet the decision support tool I am 
hoping to have 😊
For best results, this still needs me as a person to incorporate changes as 
they are made/chosen or to manually update maps etc.

Maybe building a webmap and letting the group switch on and of proposals (by 
(de)selecting them in the webmap legend) is still a fancier idea. This however 
requires me to build a map with 60 layers, one for each proposal, all uising 
the same basic nation-map and adding information to 1 municipality... That 
doesn’t sound effective. And then they still have to make changes in two files, 
with consistency errors waiting to happen.

Any fresh ideas?
Is it possible to incorporate a map directly into MS excel? So the map part is 
visual within Excel, maybe even without the use of qgis?

To be honest, opening the attribute table and edit some cells manually in an

The case of which version of QT the software is being built against is 
specifically addressed in the BUILD documentation. It has been possible 
in previous versions of the software to build against either QT4 or QT5.

I will have a look to these docs. Perhaps the most important thing is

The ideal solution would be to link all standard libraries to qt5

Yes, you choose the layer and column and it shows all statistics. It can

Hi Jeroen,

If I understand you correctly, you just want to color entire municipalities 
based on information in one or few columns? And the challenge is cooperating 
with others, who don't know QGIS?

You could use a shared drive, like dropbox, to store 3 files:
1 table (xlsx or csv)
1 geo layer with municipalities (gpkg or shp)
1 qgis project, with the table joined to the layer, and with the desired style

Others can update the table, and you (and others) can open the project and see 
the updated map in qgis.

Would that work?

 For now, I am thinking along the following line:

 All municipalities as fields with attributes being whether or not
 they have a proposal and specific information about the proposal
 such as budget needed, type of project, etc.

 That would mean 1 layer with all the proposals. That way it seems
 easier to show the entire map (all municipalities white, just

 easily see the spread.

 Hi,

 It's not clear how your data is organized, making it dificult to
 help in such a specific request. All the porposals are in the same
 layer, or in diferent layers?

 __ __

 Still, if you put all the proposal layers in mutually exclusive
 group, it will be easy to swap between proposals.

 __ __

 If they are all in the same layer, you can categorize and in the
 legend you can select which proposal to show.

 __ __

 
https://docs.qgis.org/testing/en/docs/user_manual/introduction/general

_tools.html?highlight=mutually#interact-with-groups-and-layers

 __ __

 You can also create an atlas with the necessary visualizations for
 each proposal and the calculus of the values you wish to show. But
 again, it all depends on how you have you data organized.

[Qgis-user] Geopackage writer slowness with GDAL != 2.1.x

2018-06-18 Thread Norwin Roosen

Hi everyone,

I have a serious performance issue when writing GeoPackage Layers on
systems running QGIS 2.18 with GDAL 2.2.3 and 1.11.3 (both Ubuntu 16
with ubuntugis enabled, Windows 7 & 10 with QGIS LTR installation):

Writing a vector layer with ~45000 Features to a (new) Geopackage
takes a few minutes instead of the usual 5 seconds, e.g. when applying
"Buffer Geometries" to the layer.

We are required to use Geopackage (Shapefile 10-character fieldname
limitation strikes again), but we cannot work with this performance..

I have one system running QGIS 2.18.16 with GDAL 2.1.4 (Fedora 27),
where the performance is as expected (on par with Shapefile writer).

It is not 100% clear yet if the GDAL version is responsible for the
issue, but it's is the only relevant difference I could make out between
the systems.


Is this a known issue?

How could I verify that GDAL is responsible?

Is it possible to swap out GDAL used by QGIS (esp. on Windows)?


Thanks for any hints!

Best, Norwin Roosen

2. in openSUSE Leap 15 the provided qwt package is precompiled

Re: [Qgis-user] trying to convert geotiff UTM toWGS84

2018-06-18 Thread Eric Fielding

If you want to change the projection of a raster image in QGIS, you need do a
reprojection by using the Raster->Projections->Warp (reproject) command that
sets up and runs the "gdalwarp" command. The "gdal_translate" command only
changes the format of a raster image. You have to use "gdalwarp" to do the
reprojection into a different projection.

Re: [Qgis-user] Using qgis as realtime decision support tool

That would work if updating the xlsx file automatically leads to an updated 
map. Does it, or do I have to renew the join every time the xlslx is updated?
I would like the decision makers to see directly what happens to the 
geographical spread if they refuse proposal 10 to 21 (for instance based on 
quality of the proposal). Because geographical spread is one of the criteria 
and this is best visualized with a map (instead of a list of municipality 
names), they can argue and reconsider choices. That's my need for 'real-time'.
Combined with the wish to make changes in just one document (xlsx being the 
easiest) in stead of two (both xlsx and qgis), I am looking for solution.

I have to look into the Statistics panel. Will that provide cumulations of a 
certain column based on a selection of fields (all the selected proposals)? And 
what is used to create that selection? Does it refresh automatically?

Hi Jeroen,

If I understand you correctly, you just want to color entire municipalities 
based on information in one or few columns? And the challenge is cooperating 
with others, who don't know QGIS?

You could use a shared drive, like dropbox, to store 3 files:
1 table (xlsx or csv)
1 geo layer with municipalities (gpkg or shp)
1 qgis project, with the table joined to the layer, and with the desired style

Others can update the table, and you (and others) can open the project and see 
the updated map in qgis.

Would that work?

Thanks for sharing, glad to know that you could finally build and run it.

We have some developer docs about building QGIS on different platforms, if
you feel like contributing to it, here is the document:

Re: [Qgis-user] QGIS 3.0.3 died on signal 11: what did go wrong? [SOLVED]

In case this is of interest, I spent a few hours tracing down the causes 
of this problem and found them:


1. in openSUSE Leap 15 "qmake" is qt4. Solution: replace "qmake" by a 
symbolic link to "qmake-qt5". I also preemptively deleted libqt4 during 
the compilation of QGIS


2. in openSUSE Leap 15 the provided qwt package is precompiled against 
qt4. I compiled my own qwt against qt5


Things went smoothly after that, but it took some effort to find out.

This is not the first time I experience hassle because of things linked 
to different qt versions. It is not fun. I hope others can read this an 
avoid the trouble.

Re: [Qgis-user] trying to convert geotiff UTM toWGS84

2018-06-18 Thread Nicolas Cadieux

Hi,
If you are using gdal translate with -a_srs "EPSG:4326", you are simply 
overwriting the CRS in the file. That is likely messing thing up as the file is 
not actually reprojected.

Re: [Qgis-user] Using qgis as realtime decision support tool

2018-06-18 Thread Raymond Nijssen

Hi Jeroen,

If I understand you correctly, you just want to color entire
municipalities based on information in one or few columns? And the
challenge is cooperating with others, who don't know QGIS?

You could use a shared drive, like dropbox, to store 3 files:
1 table (xlsx or csv)
1 geo layer with municipalities (gpkg or shp)
1 qgis project, with the table joined to the layer, and with the desired
style

Others can update the table, and you (and others) can open the project
and see the updated map in qgis.

Would that work?

easier to select.

Then you can use the Statistics panel to show the stats over a column,
for example the budget sum.

For now, I am thinking along the following line:

All municipalities as fields with attributes being whether or not
they have a proposal and specific information about the proposal
such as budget needed, type of project, etc.

That would mean 1 layer with all the proposals. That way it seems
easier to show the entire map (all municipalities white, just
borders, and all municipalities with proposal coloured), so to
easily see the spread.

Hi,

It's not clear how your data is organized, making it dificult to
help in such a specific request. All the porposals are in the same
layer, or in diferent layers?

__ __

Still, if you put all the proposal layers in mutually exclusive
group, it will be easy to swap between proposals.

If they are all in the same layer, you can categorize and in the
legend you can select which proposal to show.

You can also create an atlas with the necessary visualizations for

again, it all depends on how you have you data organized.

Hello,

I am thinking about using qgis as a real-time decision support
tool and I am looking for some good ideas to ease the process.

The case is the following:

I have proposals from 60 municipalities (out of a possible few
hundred), each has 1 proposal. There is only room for 20
proposals to be accepted. One of the criteria will be the
geographical spread of the proposals: it is preferred to have 20
proposals sort of evenly spread over the entire country, instead
of having the majority of them coming from one region.

My idea is to show these proposals on a map by colouring the
municipalities. As a decision support tool I need the ability to
adjust the selection in real-time (during the discussion). The
easy way is to just edit the attribute table or to select or
deselect specific municipalities. This however requires myself
to be present and make changes in qgis as the discussion goes
(given that nobody else in the decision group knows how to work
with qgis).

An alternative is to produce a webmap and have each municipality
with a proposal have it’s own specific attribute value (but all
using the same colour in categorized style), so they all show up
in the map-legend, and any group member can easily select or
deselect a specific municipality from the legend.

Do you have other ideas how to use a map as a real-time decision
support tool?

I agree that one layer would be preferable. Using the categorized renderer
would make it easy to select and deselect proposals. You can create the
classes with  a mix of the name of the munucipality and the bugdet,  that
way that is visible directly on the  legend, making it easier to select.

Then you can use the Statistics panel to show the stats over a column, for
example the budget sum.

Re: [Qgis-user] Using qgis as realtime decision support tool

I have not organized the data yet, that will depend on the pro’s and con’s of
idea’s how to use it.

For now, I am thinking along the following line:

All municipalities as fields with attributes being whether or not they have a
proposal and specific information about the proposal such as budget needed,
type of project, etc.

That would mean 1 layer with all the proposals. That way it seems easier to
show the entire map (all municipalities white, just borders, and all
municipalities with proposal coloured), so to easily see the spread.

Hi,

It's not clear how your data is organized, making it dificult to help in such a
specific request. All the porposals are in the same layer, or in diferent
layers?

Still, if you put all the proposal layers in mutually exclusive group, it will
be easy to swap between proposals.

If they are all in the same layer, you can categorize and in the legend you can
select which proposal to show.

proposal and the calculus of the values you wish to show. But again, it all

Quality of the proposal is the main criterium, but in addition to the

the cumulative budget for the selected proposals (the cumulative budget is
capped). Since I am not well known with database and calculation options in
qgis and how to automatically show the results, I am building an easy to use
excel file that will show all this information using precoded calculations,
much like a dashboard. Simply selecting and deselecting proposals in an excel
interface show you the changes in variety of projects and cumulative budget.
This is much easier for the decision team to do themselves, since MS Excel is a
well known environment.

Ideally I get the two connected somehow, so selecting and deselecting proposals
will alter the results in both the map as in the excel dashboard. However,
altering data in excel doesn’t automatically change the results in a qgis map,
because they are not connected in real-time.

Do you have any ideas how to make a real-time connection between MS Excel and a
qgis map? Or information on how to use qgis internal capabilities to calculate
certain values based on the selection of proposals? However, the last option
will probably still need myself to be present to somehow select or deselect the
proposals in qgis.

Greetings,

Jeroen

Re: [Qgis-user] QGIS 3.0.3 died on signal 11: what did go wrong?

Thank you for this insight. You are right, it is indeed libqt4 that gets 
linked, despite all of libqt5 being present. I will have to figure out a 
way around.


Thanks again

Re: [Qgis-user] Using qgis as realtime decision support tool

2018-06-18 Thread Alexandre Neto

Hi,
It's not clear how your data is organized, making it dificult to help in
such a specific request. All the porposals are in the same layer, or in
diferent layers?

Still, if you put all the proposal layers in mutually exclusive group, it
will be easy to swap between proposals.

If they are all in the same layer, you can categorize and in the legend you
can select which proposal to show.

https://docs.qgis.org/testing/en/docs/user_manual/introduction/general_tools.html?highlight=mutually#interact-with-groups-and-layers

You can also create an atlas with the necessary visualizations for each
proposal and the calculus of the values you wish to show. But again, it all
depends on how you have you data organized.

Re: [Qgis-user] QGIS 3.0.3 died on signal 11: what did go wrong?

If as you state there were no build errors then the issue probably would 
be expected to be in one of the dependencies.


Whilst it is possible to build on many versions of Linux, different 
distros can use different versions of the dependency packages from other 
distros, causing problems for developers.


The Qgis project doesn't maintain a separate repository of packages for 
openSuse. The built packages are the ones supplied by the distro, which 
last time I checked was up to 3.0.1 which I am running on a Tumbleweed 
VM. This reflects the difficulty of building and maintaining packages 
for multiple distros.


If you aren't able to find a cause of this problem, then running Qgis on 
Debian or Ubuntu in a virtual machine is likely to be the most stable 
option for you if your computer has sufficient resources to do this.

[Qgis-user] trying to convert geotiff UTM toWGS84

2018-06-18 Thread Donald Harter


I started out trying to merge some geotiff topo maps of a state.  I kept
getting results that were all black.  It seems that style was palletee
unique values and that merge could not handle that.  So I converted them
to multiband color using gdal_translate.  Some of the merged topos were
not lining up next to each other as they should.  It seems that they
were on the edge of a UTM region, each one in a different one.  So I
decided to convert them to WGS84 latitude and longitude.  I can
partially do that but when I display the files the coordinates seem to
be in utm instead of latitude and longitude.
Here is info on one such file:

Its coordinates are EPSG:4326, but they display as UTM and not latitude
and longitude.  It is as if the pixel data coordinates were not
converted but everthing else one.  I have tried gdaltransform and
gdal_translate.
So how do I do this? Maybe I am forgetting a parameter.
Here is what I ran on the command line after the gui did not work:

gdal_translate -a_nodata 0.0 -ot Byte -a_srs "EPSG:4326" -expand rgba
-of GTiff /srv/data/nm_topo/scale_250k/c33106a1.tif /tmp/out2.tif

gdalwarp  -ot Byte -s_srs "EPSG:4267" -t_srs "EPSG:4326"  -of GTiff
/srv/data/nm_topo/scale_250k/c33106a1.tif /tmp/out2.tif

I am using the latest version of qgis.  If I try to use -expand in the
processing gui for translate it says that it is an invalid parameter.
It works on the command line though.

[Qgis-user] Using qgis as realtime decision support tool

Hello,

 

I am thinking about using qgis as a real-time decision support tool and I am
looking for some good ideas to ease the process.

 

The case is the following:

I have proposals from 60 municipalities (out of a possible few hundred),
each has 1 proposal. There is only room for 20 proposals to be accepted. One
of the criteria will be the geographical spread of the proposals: it is
preferred to have 20 proposals sort of evenly spread over the entire
country, instead of having the majority of them coming from one region.

 

My idea is to show these proposals on a map by colouring the municipalities.
As a decision support tool I need the ability to adjust the selection in
real-time (during the discussion). The easy way is to just edit the
attribute table or to select or deselect specific municipalities. This
however requires myself to be present and make changes in qgis as the
discussion goes (given that nobody else in the decision group knows how to
work with qgis).

An alternative is to produce a webmap and have each municipality with a
proposal have it's own specific attribute value (but all using the same
colour in categorized style), so they all show up in the map-legend, and any
group member can easily select or deselect a specific municipality from the
legend.

 

Do you have other ideas how to use a map as a real-time decision support
tool?

 

Quality of the proposal is the main criterium, but in addition to the
geographical spread there are others as well, such as variety in projects
and the cumulative budget for the selected proposals (the cumulative budget
is capped). Since I am not well known with database and calculation options
in qgis and how to automatically show the results, I am building an easy to
use excel file that will show all this information using precoded
calculations, much like a dashboard. Simply selecting and deselecting
proposals in an excel interface show you the changes in variety of projects
and cumulative budget. This is much easier for the decision team to do
themselves, since MS Excel is a well known environment. 

Ideally I get the two connected somehow, so selecting and deselecting
proposals will alter the results in both the map as in the excel dashboard.
However, altering data in excel doesn't automatically change the results in
a qgis map, because they are not connected in real-time.

 

Do you have any ideas how to make a real-time connection between MS Excel
and a qgis map? Or information on how to use qgis internal capabilities to
calculate certain values based on the selection of proposals? However, the
last option will probably still need myself to be present to somehow select
or deselect the proposals in qgis.

 

Greetings,

Jeroen

Re: [Qgis-user] Copying styles issue in 3.0

Good day

It appears since 3.0 that there is a problem when a style is copied
from one layer to another.

In the previous editions I can recall value maps for specific fields
would be copied between layers.

In 3 I am finding the value map is not copied, meaning each value map
has to be laboriously copied by hand as there is no means of exporting
a value map from an existing layer.

I have found value maps are not copied between shapefile layers, or
from a shapefile to a geopackage. All other style data appears to copy
successfully.

Do you have any comment or should this be filed as a bug.


Hi Patrick,

no comment (as I did not encounter this yet), but this sounds like an 
issue, so I would always file an issue first, adding some 
data/projectfile/steps to reproduce. And then sent an email to the dev 
list pointing to your issue.


Then it is (even for non devs) easier to reproduce and confirm, and devs 
are more sure it is an actual issue to be picked up.
