[Qgis-user] Add elevation data to many gpx files

[APM]

Dear List,



is it possible to add elevation data to gpx files with Qgis?

I have a high amount of gpx-files and would have to add the data's in a 
batch.




Thank you!

[Qgis-user] Disassemble GPX files

[APM]

Dear Qgis-user,


I have a lot of gpx-files, which contain several tracks each.


Is it possible to disassemble this files in several files in a batch, 
which contain only one track each?


The file name should be the  tag of the track.


I use a Linux system with a self compiled Qgis 3.20.

But maybe there's a solution in addition to Qgis with command line, gdal 
etc. ?



Thank you!


Kind regards

Hi Andrea,


I changed the files, all is o.k. now.

Is this o.k. as well, to report such errors or will they be fixed anyway?

I compiled Qgis from github.
If I install the build with make install I got the message:

Hi Piet,
this issue is similar to the one previously also reported by you some 
months ago.


It seems to me there is again an issue in the source code files 
qgscoordinatereferencesystem.cpp and qgscoordinatereferencesystem_legacy.h


You should be able to fix the issue patching the lines 2357 and 2358 
of src/core/proj/qgscoordinatereferencesystem.cpp


from:

  int nextSrsId = 63560;
  int nextSrId = 520003560;


to:

  int nextSrsId = 63561;
  int nextSrId = 520003561;



and the last lines of src/core/proj/qgscoordinatereferencesystem_legacy.h

from:

  {"OGC:CRS83", "63559,520003559"},
};


to:

  {"OGC:CRS83", "63559,520003559"},
  {"EPSG:20904", "63560,520003560"},
};

Re: [Qgis-user] Build error on Debian testing 'bookworm'

[APM]

Dear Richard,


you're right:


The name of the Debian package is sip5-tools.

I delete it, and I delete sip with 'pip3 uninstall sip' as well.

The compilation works fine now.


If I reinstall sip5-tools, the build fails again.


Thank you for your help!


Kind regards


Piet

Hi Piet,

I'm not 100% sure if this is a good solution.

Installing sip with pip or pip3 means you are pulling sip-stuff from the python 
repo's, while I think it is preferred to keep plain Debian (python/sip) 
packages for compiling QGIS yourself.

I build on a aging system myself, so I'm not very aware of which sip I exactly 
use... but I cannot find a 'sip5' package, only sip5-doc and sip5-tools (both 
also not installed on my system...
Ah:
  `dpkg -S /usr/bin/sip`
tell's me it comes from sip-dev package (sip-dev/testing,testing,now 
4.19.25+dfsg-1), so I think that is what I actually use to build QGIS...

The 'Debian control' file of QGIS [0] shows that (for the packaging build) 
there is a dependency on 'python3-sip', and:
  `apt show python3-sip`
show me that it's source comes from 'sip4'(!)... so maybe you installed sip5 
via other sources?

I hope this is helpful...

Regards,

Richard Duivenvoorde

[Qgis-user] Find / checkout different branches Github

[APM]

Dear List,


my questions are more related to the git system, but I hope you'll give 
me some information.



I like to compile QGIS on my own following

https://github.com/qgis/QGIS/blob/master/INSTALL.md#36-check-out-the-qgis-source-code

But I like to compile Qgis 3.20 and not the developement version.


My questions:


How to find the avaible versions ("branches"?) by using a 'git'-command ?

How to checkout a special version?


Further, what is the difference between "backport-43897-to-release-3_20"

and "backport-44030-to-release-3_20"?


Futher, I red that there's a version 3.20.1, but I can't find it?

Is this the 'master' branch?


Thank you very much!


Kind regards


Piet

[Qgis-user] Compiling with 3D, how to setup ccmake

According the manual

[Qgis-user] Working with GIT in case of changes in src

[APM]

Dear List,


my question is not related to Qgis directly, but I would be glad, if you 
could help me.



On a Debian Bullseye I compiled Qgis and changed the file

src/core/proj/qgscoordinatereferencesystem.cpp

manually, because the orginal file contains a bug, which is already 
reported.


I think, this bugs will be corrected in the orginal source files soon.

But I do not know when.


If I start 'git pull', git ask me to 'commit' or to 'stash' my changes.


Make it sense to keep my manual changes until the change is in the 
orginal source code?


Could this 'keep' cause other errors, because my local source files do 
not fit to the branch anymore?



Kind regards


Piet

Tested on QGIS 3.18.3 and Arch Linux.

To get the patch:
1.) Go to the issue that Andrea referenced at

<https://github.com/qgis/QGIS/pull/43671> and click the "commits" tab
2.) copy the patch link with the clipboard button and paste that into

https://github.com/qgis/QGIS/commit/4036e3d6ae71ffefc48a22295e338f59502949bb.diff 
<https://github.com/qgis/QGIS/commit/4036e3d6ae71ffefc48a22295e338f59502949bb.diff>


that's the patch file =) download it or put it in a notepad and save it.

This particular patch is being applied to 'master' so it's important 
to Find & Replace the reference to the /proj/ folder.
It's because the /proj folder doesn't exist in the 3.18.3 source 
package and the patch won't apply.


Then, you can change directly into the qgis source folder after you 
extract it, apply the patch, then make, make install.


cd 
patch -Np1 -i /srs-fix.diff

is an example of applying the patch with the 'patch' utility

Tested on QGIS 3.18.3 and Arch Linux.

To get the patch:
1.) Go to the issue that Andrea referenced at 
https://github.com/qgis/QGIS/pull/43671 
<https://github.com/qgis/QGIS/pull/43671> and click the "commits" tab
2.) copy the patch link with the clipboard button and paste that into 
your browser

3.) add .diff to it like so,

<https://github.com/qgis/QGIS/commit/4036e3d6ae71ffefc48a22295e338f59502949bb.diff>


that's the patch file =) download it or put it in a notepad and save it.

This particular patch is being applied to 'master' so it's important 
to Find & Replace the reference to the /proj/ folder.
It's because the /proj folder doesn't exist in the 3.18.3 source 
package and the patch won't apply.


Then, you can change directly into the qgis source folder after you 
extract it, apply the patch, then make, make install.


cd 
patch -Np1 -i /srs-fix.diff

is an example of applying the patch with the 'patch' utility

Hello Saulteau,


I'm unsure, if I understand your information right.


1. Go to the issue that Andrea referenced at   > ok


2. copy the patch link with the clipboard button.

I think this is the button on the right side beneath "Verified". If I 
press it   in Firefox


I have "4036e3d6ae71ffefc48a22295e338f59502949bb" in the browsers clipboard.


So I copy and paste the file directly and stored it as 'srs-fix.diff':


If I use the command


patch -Np1 -i /home/user/tmp/srs-fix.diff


I get the message:

---

There are lines, which crosses other lines in the same layer.

Can I extract this crossing points?

I try to use the "Vector Intersection tool", which is demands an Input

It extracted some nodes, but not all.

Can you give me a tipp, please?

Re: [Qgis-user] GPX group, add field "name" from track layer to attribut table point layer

[APM]

Dear Greg,


thank you for your kindly answer!

Meanwhile I found a solution for my problem.

I can use the menu "Extract Vertices" to solve my problem.

This creates a usable point layer with the needed "name" field.


The "tracklogs" you mentioned are GPS-Tracks from a GPS-Device?

I use the same for my map.


But anyway, I'll check your remarks about the bounding boxes!

The "tracks" layer contains a field "name" in the attribute table.

This field is not in the "track_points layer".

I have also been loading GPX of tracks, but in my case they are actual
tracklogs rather than trail geometries.  I'm not sure which you have.

Generally, I have loaded tracks and not loaded trackpoints.   This has
seemed like a good choice except for brief tracks at fixed locations (as
a form of position averaging to get a more reliable/accurate position
for a point).   But for tracks that represent trails, I find that the
trackpoints just cause clutter and I don't find them useful.  They are
implicitly present as vertices of the multilinestring.

I wonder if you are rendering track points, and if so why (you probably
understand something I don't; that's not meant to be "don't do that").

As for labeling, it seems pretty normal to have name labels on
multilinestrings, as that's basically how roads are, and it seems
labeling attempts to avoid overlap anyway.

I wonder if your svg object is somehow bigger than its bounding box, so
qgis thinks it doesn't overlap but yet it does?

[Qgis-user] GPX group, add field "name" from track layer to attribut table point layer

[APM]

Dear List,

if I import a gpx file via "Data source manager", I get a group with two 
layers:


1. "track_points" as PointZ layer

2. "tracks" as MultiLineStringZ

The "tracks" layer contains a field "name" in the attribute table.

This field is not in the "track_points layer".

Is there a way to add the field "name" in the "track_point" layer, so 
that every point has the track name which he belongs to?


I need this to create a map with hiking signs of the tracks. I use the 
field "name" to get the relation between hiking signs and the tracks.


Basically it works, but I have overlapping SVG signs in the map.

To avoid this overlapping, I try to use the "point displacement" in the 
"Symbology" menu. But I'm not sure if it will work. Maybe there is a 
better way to avoid the overlapping.


Thank you for you help!

[Qgis-user] Overlapping SVG Symbols

Dear List,


I like to create a map with gpx tracks. This tracks I imported as a 
vector layer.


Every track has a SVG Symbol which are defined in the menu Symbole > 
Line > Marker Line > Marker > SVG Marker


Works fine so far.

But at common points of the tracks,  the SVG symbols overlap each other 
and are not visible correctly.



I played a bit with 'Marker line" and 'Intervall', but I have no success.


I'm not an native English speaker, but I hope I pointed out my problem.

[Qgis-user] How to create a hiking map with Qgis and OSM

[APM]

Dear all,


I like to create a hiking map with Qgis and ask you for some help.

My system is a small laptop with Debian stable and Qgis 3.12.1.


As a base I to use the WMS server https://ows.terrestris.de/osm/service

I like to use OSM to avoid trouble due to legal things.


I added a vector layer with WGS84 / UTM 32N and a gps vector layer.

The related gpx file is loaded with the plugin gps tool.




My first question is how to setup a scale 1:10.000?

Maybe it‘s possible to print a map with fixed scale?


Further the printed .pdf has very small letters, which are not readable.

Can I enlarge the letters or is it given by the WMS server?


Generally I like to ask if I have to render a map if I would use a 
vector layer based on a OSM .pbf file in every case.

Is there a simple tool for linux to do the rendering?


I found only older tools or a very comlex solution with a comlete server.


Thank you very much for your kindly help!


Kind regards
