qgis-processing-saga-nextgen's Issues

Natural-Neighbour and Shapefile size limit

I am trying to run the natural-neighbour module in Saga 9.2 and ran into a block, which I assume is due to the size of the shapefile limit:

input is a set of points in gpkg format (about 200 million points)
output desired is a grid of 12000x12000 pixels.

The program (natural neighbour - same for thin plate) first saves the gpkg file into a shapefile into a temp directory.
I note that the program seems to proceed well but stays put at 100% complete and nothing seems to happen, even though the CPU and memory continue to operate - no error message is indicated in the log.

I tried to conver the gpkg file to a shapefile, but QGIS gives an error as the shapefile exceeds 4Gb.

Is there a solution? I wish Natural Neighbour could take multiple input point files, but that does not seem to be possible.
Perhaps I need to break up the problem into smaller grids and join them later... but that is not ideal (edges will need to be smoothed etc).

Perhaps eventually the gridding routines could be improved to handle such large datasets.

Any suggestion welcome.

What version of SAGA is available with Ubuntu 19.10 ?

At moment I have QGIS 3.12.2 in ubuntu 19.10 but SAGA no is compatible with this version, however I installed the plugin "processing saga nextgen" and still I have problem with the version 7.3 of SAGA

Unsupported SAGA Version

I just installed SAGA 7.2.0 on my Linux Mint 19. But The Qgis Log Messages said:

2020-02-12T14:55:08     CRITICAL    Problem with SAGA installation: unsupported SAGA version (found: 7.4.0, required: 7.2.).

2020-02-12T14:56:36     CRITICAL    Problem with SAGA installation: unsupported SAGA version (found: 7.4.0, required: 7.2.).

I believe i have install the 7.2.0 version of SAGA:
$ saga_cmd -v
SAGA Version: 7.2.0

I also have set the SAGANG folder to the installation directory.

Any assistance you can provide would be greatly appreciated.

[Feature Request] Link to documentation

This is a feature request to create a link or a help button in Processing algs window, to have direct access to SAGA documentation

http://saga-gis.sourceforge.net/saga_tool_doc/7.2.0/

With the processing_saga_nextgen plugin enabled, qgis_process sends many extra lines to standard output

This is likely to cause errors when standard output is processed further; it also happens with --json:

Adding modules that are in SAGA

ciao,
I'd like to know if it's possible to add modules that are already present in SAGA.
for example, I'd like to use in QGIS the SAGA modules about slope stability.
Can I add by mysellf this modules or it is necessary to update the plugin?

thank you for your reply and ciao!

Raster/grid normalization algorithm

What is the bug or the crash?
In version 3.22 the minimum and maximum options for interval definition in Saga's grid normalization algorithm (formerly raster normalization) are missing. I noticed this both in the old SAGA repository, and in the nofo SAGA Next Gen In version 3.16 these options were present. This makes it impossible to use the algorithm correctly. In version 3.22.13-Białowieża (qgis/QGIS@02ff117) is no longer available, as it was in version 3.16.5-Hannover (qgis/QGIS@58ba7c1).

Steps to reproduce the issue
Activate Processing, Processing Saga NextGen Provider and SAGA GIS provider plugins;
Go to Processing tool box;
Search for Raster Normalization or Grid Normalization;
Open the plugin and check if the minimum and maximum options are available;
In version 3.22.13-Białowieża (qgis/QGIS@02ff117) is no longer available, as it was in version 3.16.5-Hannover (qgis/QGIS@58ba7c1);

SAGA NextGen Provider QGIS plugin -> SAGA not visible in processing toolbox - RESOLVED

Not sure if anybody encountered this issue with the SAGA installation in QGIS:

After installing SAGA 9.2 using OSGeo4W in windows and activating the Processing SAGA NextGen Provider plugin in QGIS (3.32.2-Lima) the SAGA tools do not show up in the processing toolbox.

I have tried installing an earlier version of SAGA (v 7) and they do show up but I get an error upon executing (in this case Natural Neighbour), indicating I need SAGA >= 9.1.

I noticed that the folder name for the SAGA installation (under C:\Program Files\QGIS 3.32.2\apps) is 'saga' for the version 7, and 'saga9' for the version 9.2 installation.
Changing the name of the folder from 'saga9' to 'saga' and reinstalling the plugin makes the SAGA package visible in the Processing Toolbox.

So, this issue can be somehow related with #3

Error in Watershed Delineation - Using SAGA NextGen plugin

From the suggestions of Nicolas Godet, member of QGIS (qgis/QGIS#50621 (comment)) on the issue "Watershed delineation Error qgis/QGIS#50621", I tried "Processing SAGA NextGen provider" as suggested by Nicolas Godet. Still we are getting the same error note as shown in uploaded image. Kindly advise how to proceed or resolve the bug.

Failed to Run on Profile with Special Charater on its Path

The SAGA processing can't be run on a profile that has a special character on its path. The original bug happens on a computer that put the QGIS directory on something like this: D:\\Users\Company\UserName\AppData(Roaming)\QGIS\QGIS3\profiles\default\processing. Note the bracket on AppData(Roaming).
To reproduce, create a new profile with a bracket on its name, for example: new(profile) then run any algorithm on it. For example, this is the error message that I got:

You can check the 'Log Messages Panel' in QGIS main window to find more information about the execution of the algorithm.

and this is the log:

Of course, we can use a "proper" naming of the profile or make sure that the QGIS directory is under a "proper" path (proper = without a special character). But it would be great to handle this case.

SAGA Upslope Area tool error: tool need graphical user interface

I've posted the same in the QGIS issues, but since the error is the same for the SAGA Next Gen plugin I'm copying the link to the issue here too:
qgis/QGIS#44514

SAGA >= 9.1 needed but currently not optimally distributed

The binary SAGA packages distributed through OSGeo4W (Windows) and ubuntugis-unstable PPA (Ubuntu) are lagging behind quite a lot, being at 7.8.2 and at 8.2.2 respectively. For Windows, an up-to-date binary build can be installed manually from https://sourceforge.net/projects/saga-gis/files/ while other platforms need to locally build from source to get it.

Currently users that make use of OSGeo4W / ubuntugis-unstable PPA (and perhaps other) repositories that distribute SAGA will get a warning after updating the plugin to version 1.0.0, like below.

Since the QGIS plugin now requests SAGA >= 9.1, I think it's a good idea to stimulate the OSGeo4W and the PPA maintainers to update SAGA in their repository.

$ qgis_process plugins

cmd.exe not found

'cmd.exe' is not recognized as an internal or external command,
operable program or batch file.

On Windows, jumping through a few hoops is required to even get SAGA visible in QGIS. First you have to install the binaries, then you have to go into QGIS settings under system environment and add the SAGA binaries path without spaces (C:\progra~1\saga). Finally install the SAGA nextgen processing plugin. This makes SAGA visible in the toolbox.

When trying to run any tool I get the error at the top. What I think is happening is that underscore needs to be escaped in the code, so calling "saga_cmd.exe" should be called as "saga\_cmd.exe".

I cannot find the code where saga is called though. Can someone point me to where this is so I can try a quick fix?

Slope, Aspect, Curvature algorithm

SAGA Slope, Aspect, Curvature algorithm is being applied in a very strange way.

Looking at log and saga_batch_job.bat file, it is running saga_cmd ta_morphometry "Slope, Aspect, Curvature" several times, each one adding a new output.

In the end, it only creates the -SLOPE output, because, in fact, looking at log, Processing only runs

[Feature Request] Use GeoPackage instead of Shapefile

SAGA supports geopackages (at least the GUI does), so it's weird to me that everything is done via shapefiles for vector formats with processing.

Context:
I ran into an issue when I needed to chain a bunch of Polygon Identity tools together. The output ended up having field errors due to the number of similar field names and the shapefile limitations. This made me have to go a different route for my model.

SAGA NextGen is not available in Windows

I was trying this new SAGA provider implementation in QGIS 3.6, on a Windows machine, but in Processing options I don't have the option to define the path to SAGA 7.2 binaries

and maybe because of that, SAGA NextGen is not available in Processing Toolbox.

Inverse distance weighted interpolation fails

The inverse distance weighted interpolation results in an 'empty' raster layer. It seems to me that the problem is that the attribute is <not set> (see screenshot). However, I did select the attribute column.

Just to see if there is something wrong with the data, I tried another saga function (kernel density estimation) using the same column, and that works without problem. I also ran the inverse distance weighted interpolation directly in SAGA, and that worked like a charm.

Plugin suddenly failing to install in unchanged Dockerfile

We have the following snippet in a Dockerfile:

RUN apt-get install -y qgis qgis-plugin-grass saga 
RUN wget -qO sagang_plugin.zip https://plugins.qgis.org/plugins/processing_saga_nextgen/version/0.0.7/download/ 
RUN unzip -q sagang_plugin.zip -d /home/rstudio/.local/share/QGIS/QGIS3/profiles/default/python/plugins

What used to work now fails : (

Any ideas on a quick fix?

See geocompx/docker#41 for context.

Thanks!

Processing model compatbility

Hello,
Thanks for all the work getting SAGA to work with QGIS! It sounds tike it can be tricky at times but there are a lot of SAGA algorithms I have trouble finding alternatives for in QGIS. Therefor I have a lot of them in my graphical models. In QGIS version 3.30 with SAGA having been removed this means that those models are now broken.
Would it be possible to make the Next Gen plugin algorithms automatically be used in their place?
It seems that maybe the only difference is that the call to the algorithm is sagang:algo rather than saga:algo. While this distinction made sense in pre 3.30 versions when there could be 2 versions of the SAGA plugin now it seems unnecessary.
I have been able to get my models to work by opening the .model3 file in a text editor and simply finding and replacing saga: with sagang: but I imagine many users will be less adventurous than me.
Thanks again.

How to use this extension

I'm sorry if I missed something. I just need some help to get this extension working.

I've compiled saga 7.2.0 on GNU/Linux, bin directory is in the path in first position. I've tried to set /path/to/saga-7.2.0 or /path/to/saga-7.2.0/bin in provider settings for SAGANG. I still can't manage to run it with processing.

What about old SAGA provider? Should it be disabled?

When things are done right, should SagaNG appear in the processing toolbox?

Is there a special way to call processing to use SagaNG?

Raster loading error in tool

Greetings Nyall,

I am using the "Line to profile" tool and during the executing I get an error when SAGA is attempting to read the raster,

The raster is originally a Float64 as opposed to my other rasters, but now even with older rasters that were ok i get the error message when reading the raster input of ta_slopes

Loading grid: C:/Users/-/AppData/Local/Temp/processing_UKaRLq/9ca10f78d5924c078ffe4636f0461416/ATHDEM5mc.sgrd... failed Error: input file [C:/Users/-/AppData/Local/Temp/processing_UKaRLq/9ca10f78d5924c078ffe4636f0461416/ATHDEM5mc.sgrd] Error: DEM

Do you have a clue what might be causing this?

What is "Target area" in Saga Upslope area?

I´m using Saga upslope area in QGIS. Using the tool with target X, Y coordinates works fine but how to use "target area"? What kind of input raster is demanded and how does the tool use this input? I ‘we been searching a lot but can´t find any useful help.

Support any newer version

How is it that this plugin is supporting the only version not listed by upstream's git?
https://sourceforge.net/p/saga-gis/code/ref/master/tags/

Also does it really need to match exactly to 7.2? Would supporting 7 be a possibility?
