Hi Volker, thanks again, working with the unique identifier worked fine. Still calculating on one of the layers (symmetrical difference of all inland water bodies including rivers for Germany will take about two days with my cpu), but the others have worked fine with that shape-method/steps. Best regards desputin
-
Hi Volker, thank you. How do I join the calculated difference of the difference layer to the original/input file? About that second way of dealing with my problem. Zonal-Grid, does that work with two shape-layers, as they are not grid/pixel based? Best regards desputin

Hi, I have two polygon-shape-layers, one with administrative regions (German Gemeinden) and one layer with agricultural spaces from corine. Now I want to measure the percentage of agricultural space for all regions. I tried to do it with "Symmetrical Difference". Layer A regions, Layer B corine. And without "splitting parts". As a result I want a list of regions with agricultural spaces subtracted so I can calculate the difference. The problem is, that after running "Symmetrical Difference", there...

Great thank you!

Hi Volker, thank you, that seems to have worked now! Can I somehow check, if I have the newer CLIPPER-version now? - Ah I see it, it says clipper2 (1.0.0.). Is that correct?

Hello, I tried compiling of Saga 8.4 with git and then run "cmake --build . --config Release" My system is Debian Stable (bullseye) but that has failed: 11%] Building CXX object src/saga_core/saga_gui/CMakeFiles/saga_gui.dir/res_commands.cpp.o /home/devel/saga-gis-code/saga-gis/src/saga_core/saga_gui/res_commands.cpp: In function ‘wxToolBarBase* CMD_ToolBar_Create(int)’: /home/devel/saga-gis-code/saga-gis/src/saga_core/saga_gui/res_commands.cpp:551:29: error: ‘class CSAGA_Frame’ has no member named...

Hellu Justus, thank you for the answer. Indeed I have a totally outdated saga version, that comes with debian (stable). It is 7.3.0! I'll make a new thread for my compiling problems.

Hi, I would like to create buffers around agricultural areas taken from corine and dissolve them. So I'm using the functionality in saga for the whole of Germany. The problem is, that even though I have a quite fast CPU (Ryzen5, 32GB Ram), it is taking forever. So my question: Would it speed up the process, if saga could somehow use multiple cores for the conversion? I suppose this is not supportet? Or does it make a big difference, if the data is stored on an ssd or a hard disk? Best regards

Wow, wow, wow. The Addon is working fine, thank you. PS in libreofffice I wouldn't have had any chance with my plan, because calc limits tables to 1024 columns...
-
Wow, wow, wow. The Addon is working fine, thank you.
-
Wow, wow, wow. Worked fine, thank you.
-
yes, I'll try that!
-
Thanks! Maybe I'll use the Windows-Build if I'm in the mood to turn on my virtualbox (I hate Windows).... When will the next version will be released?
-
Oh that's great! So in the next version of saga it will be implemented?

Hi, I created a CSV-Table with the SAGA-functionality "Point Distance" ("each pair with a single record") In my case I calculated all Distances from German "Gemeinden" to towns in Germany (from OpenStreetmap). What I would like to have is the minimum distance to the next town for each "Gemeinde". But I have all distances to all towns. So I will probably have to filter the lowest distance to the next town only in LibreOffice, correct? Or can I do this somehow in SAGA? best regards desputin

Hi Olaf, one more question: I imported the polygons_line_length.xml. and Saga said "loading .... okay". But it is not visible in the menu "tool chains". Any idea why this is like that? And how I can load it? The Saga version is 7.8.0 (debian)
-
Hi Olaf, thank you. The sourcforge website is kind of confusing so I didn't find my post.
-
Hello, I'm not sure if I have already asked this, but but how do I measure total lenght of lines within Polygons? The Length then should be inserted into the meta data of the polygon-layer... best regards desputin
-
Thank you, that works fine!

Hi Volker, thanks for the quick answer. I removed version 2.3.1 and re-compiled the git-version 7.8. But the Addons in the menu are still missing. How do Ioad the libraries from the /usr/local/lib/saga folder? best regards desputin

Strange... I have installed Version 7.8.0 now but when I run /usr/bin/saga_gui Version 2.3,1 probably from debian stable comes up. So I have to run: /usr/local/bin/saga_gui But in Version 7.8.0 most addons are missing under "Geoprocessing"..... I don't understand why. I compiled the program according to the wiki handbook.
-
Solution: When running /usr/bin/saga_gui it works. There might be an error in the installation/compillation...
-
Hi Olaf, now I have installed the new version of saga but couldn't find the function in the Geoprocessing menu. There seem to be quite a few addons missing. I think it might not be installed correctly (I followed the install directions for debian with git sources)...
-
Hi Olaf, all right thank you. I will download the new version then!

Hi, I would like to measure the shortest distance from multiple points to a any part in a coast line of four different costs. How do I do this with SAGA Gis? In my case the points are centroids of German "Gemeinden" and the cost lines are the lines of the Baltic- the North Sea, the Atlantic and the Mediterranian. So it would be best, if within the meta data of my points there is a column for each sea. E.g. Like this: Distance to North sea: 308 km / Distance to Atlantic: 751 km.... And so on. Is that...

SAGA is my preferred tool (workhorse) for all the processing but for combining the layers and producing the final map for printing etc. I am using QGIS. Same for me! My experience is that saga is much more stable and reliable when calculating stuff. But Qgis has the better gui when it comes to putting all layers together to export them to the final layout....

Hi Jan, thank you! That was easy in qgis :)

Hello, I would like to transform a Gauss-Krüger 3 Grid file do WGS84 UTM33N. I had already asked something quite similar in the past, but that was for shapes, if I remember it correctly: https://sourceforge.net/p/saga-gis/discussion/790705/thread/a824273a/?limit=25#567a So now my grid data is this: https://opendata.dwd.de/climate_environment/CDC/grids_germany/multi_annual/precipitation/ And it is in Gauss-Krüger. best regards desputin

PS I compiled SAGA from Source under Debian Stable. But one package was missing in the wiki instructions (https://sourceforge.net/p/saga-gis/wiki/Compiling%20SAGA%20on%20Linux/) in order to make SAGA work. The package name is: lib32stdc++6 Maybe you can add it to the Debian/Ubuntu Howto...

Hi Olaf, thank you very, very much! This XML ist just great - what a support! I had to update SAGA for that to the current version. In Debian Buster/Stable the Version is 2.3.1 (!) Best regards Christopher

Hi, I didn't find the function, but I think it is there somewhere: "Measure total length of lines within polygones" Could anyone tell me where to find it in the saga gis menu? best regards desputin

Jep it worked thanks. I have a master Table so I'm opening the dbf file in LibreOffice manually and exporting that new Column... Saga gis is great!

Hi Volker, thanks for the quick answer! Hm, but I think with your suggestion, I would only take attributes from the "Gemeinden". But it's the other way round: The attributes I want ot add to the "Gemeinden" are stored in the "Landkreise"... So if I understand this correctly, the correct way would have to be: 1. Create the centroids from the "Gemeinden" as you said 2. Add Polygon attributes from the "Landkreise" to these points ("add polygon attributes to points") 3. Add these Point attributes to...

Hello, I have two polygon shape-layers for German administrative "Landkreise" and German "Gemeinden". The layer of the "Landkreis" always contains several "Gemeinden". Now I have a certain attribute in the "Landkresie" (the bigger polygons), I would like to add to the attribute table of the smaller polygons of the "Gemeinden" - which are within the "Landkreise". Could anyone here tell me how I do that with saga? best regards
