Re: [Qgis-user] Sextante in QGIS
Anyway, forget what Sextante was (is?) for Gvsig. There it was both the toolbox and the algorithms, now it's the container of multiple algorithm sources (grass, saga, qgis itself, etc.). Many algos that you could find under Gvsig Sextante are provided by Saga... where Sextante itself started from. giovanni Il 06/mag/2015 09:16 Matteo Ghetta matteo.ghe...@gmail.com ha scritto: Hi Rafa, from QGIS 2.0 Sextante has been included in QGIS with the name of Processing.

Re: [Qgis-user] SEXTANTE for QGIS has been released
Hi Victor, A great idea, the original one :-). I am sure you are right the way data is organized in GRASS is scary for new users. It took me some time before I got used to GRASS and its way of data organization. And although I like it very much now, it is a steep learning curve. So this would really open the GRASS set of functions for a much wider audience. I am also happy you are planning the other way around for the near future. Unfortunately I cannot offer much help in terms of programming, but when the time is there, I am happy to do some testing if needed. Best regards, Paulo On 04/02/2012 12:10 PM, Victor Olaya wrote: Paulo, The idea (at least, my original idea) was to let users with no GRASS knowledge to use GRASS algorithms from a more common GIS interface. So they do not have to worry about mapsets and things like that, and they execute the algorithm just like they would do with any other one. The mapset and location is created automatically each time the algorithm is run, and all data imported into it. Then the results are exported and loaded in the GIS. This might have some limitations, of course, but in the Java version of SEXTANTE it has proved very useful to make those algorithms available to most users, specially those that were a bit afraid of the complexity of GRASS or were not used to its interface or its command-line syntax. Using GRASS layers is a different thing, but as I said, I hope to have that already in a near future, and also to be able to use those GRASS layers in other algorithms, so SEXTNATE will become the intermediate layer for all analysis and data sources, and doing it as transparently as possible Regards El día 2 de abril de 2012 11:54, Paulo van Breugel p.vanbreu...@gmail.com escribió: On 04/02/2012 09:47 AM, Paolo Cavallini wrote: On 30/03/2012 23:19, Victor Olaya wrote: Well, the idea is just the opposite: to use any raster or vector layer in GRASS, directly from QGIS.

Just to be clear, I assume you mean here that there is no need to convert (import) other raster layers to GRASS layers in order to use GRASS functions? I am asking because this option doesn't help the user who has his/her data in a GRASS database. For me the strict and transparent handling of region settings and projection has always been one of the strong points of GRASS, and I am curious how the workflow will be when working with external rasters. Like with internal rasters, an external raster layer does need to be in the same projection as the current location. Furthermore, raster functions use the region settings (extend, resolution) of the current mapset as far as I understand. When importing, it is possible to create a new location on the fly based on the raster you are importing. This makes it easier to deal with the above (I think), e.g., by creating a temporary location. I am not sure linking an external raster offers the same option (I had a quick look, but can't find the option, but maybe I just overlooked it). But then, the normal import function allows to create a location based on a raster without actually importing the raster. So the two could be combined. ___ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user ___ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user

Re: [Qgis-user] SEXTANTE for QGIS has been released
I've just tested a dozen of SAGA algorithms, and they worked smooth! ;) (ok, I admit, I'm on Windows :D) @Gerhardus, Victor will be able to give you much more informations in the near future. Sextante is like a toolbox, where pieces of functionalities are kept together. It can leavarage external softwares (like SAG, R, Grass), it can incorporate python scripts, etc., and it expose them to the user in a uniform manner. The user will be able to chain these pieces together, even through a graphical tool (the modeler), and he doesn't have to worry much about where they come from, and how they are being called. So, what is SEXTANTE good for? - users: for the reasons I've just said. A lot of different code are exposed in a coherent manner - developers: incorporate their algorithms inside the toolbox, and don't have to worry to manage user inputs, outpus, the GUI, etc. and they can also use the other tools available from the toolbox...

You can access it selecting the SEXTANTE help option in the SEXTANTE menu. This version is still missing some functionalities, but should be fully usable. Users should be particularly aware of the following issues: -External applications (SAGA and R) have been tested mostly on Windows, but not so much in Linux, so problems might appear on that platform. No testing has been done at all under Mac OS. -GRASS algorithms have been deactivated, in order to have a working version as soon as possible. We hope to have GRASS incorporated into the set of available algorithms pretty soon -Although most algorithms support multiple formats for their ouput layers, these are currently limited to tiff for raster layers, shapefiles for vector layers and dbf files for tables. This can be changed easily and will be done in a next version -Calling external applications might not work if using layers such as those coming from remote services or DB connections. Please, use just file-based data by now (we are working on improving that as well, but it might take time... ;-) ) -Using tables (and also opening those generated by geoalgorithms) is still a bit in development, since there is no built-in default method of opening independent tables. By now, attribute tables of vector layers can be used, but only if these are in shapefile format (since we can refer to the associated dbf file). We expect to change this soon, probably creating some plugin to improve that handling of independent tables (or if anyone can point us to an existing one that can be coupled with SEXTANTE, that good be even better...) Once again, read the manual before trying it, as it will greatly help you to understand SEXTANTE and what you can do with it. For developers: I know a lot of documentation is needed...hope to have that solved soon (or at least start to solve it). A SEXTANTE for QGIS developers manual is also on its way... there is already a mechanism to create QGIS plugins that register new algorithms in SEXTANTE (thanks to Alexander Bruy for the suggestion!), but still has to be documented.
