Do you need Sextante to configure Saga?
If you are running Linux, SAGA binaries are not included with SEXTANTE, so you have to download and install the software yourself. Please check the SAGA website for more information. SAGA 2.1 is needed. In this case, there is no need to configure the path to the SAGA executable, and you will not see those folders.
Can a saga algorithm be run from QGIS?
SAGA algorithms can be run from QGIS if you have SAGA installed in your system and you configure the processing framework properly so it can find SAGA executables. In particular, the SAGA command-line executable is needed to run SAGA algorithms.
Can a QGIS be used to execute external algorithms?
Once you have correctly configured the system, you will be able to execute external algorithms from any component like the toolbox or the graphical modeler, just like you do with any other geoalgorithm. By default, all algorithms that rely on an external appplication not shipped with QGIS are not enabled.
Is the saga catchment area tool not working?
I’m trying to use the SAGA Catchment Area tool within QGIS and I don`t get a result. The log file is the following:
How can I configure QGIS to run Saga?
Make sure you install QGIS in your system using the standalone installer. That will automatically install SAGA, GRASS and OTB in your system and configure them so they can be run from QGIS. All the algorithms in the simplified view of the toolbox will be ready to be run without needing any further configuration.
How to export data from Saga to grass?
So whatever method we used to import data to SAGA we can export them only using transactional GeoTiff. Two methods of export are possible: export from SAGA to GeoTiff and import file by file (every file in separate command) or: export from SAGA to multiband GeoTiff (one file) and next import it to GRASS as set of bands.
How to configure Saga on Windows 2.1?
If you have installed SAGA yourself (remember, you need version 2.1), the path to the SAGA executable must be configured. To do this, open the configuration dialog. In the SAGA block, you will find a setting named SAGA Folder. Enter the path to the folder where SAGA is installed.
Can a provider not using an external application use QGIS?
Providers not using external applications can process any layer that you can open in QGIS, since they open it for analysis through QGIS. Regarding output formats, all formats supported by QGIS as output can be used, both for raster and vector layers.
