Hi, deriving valid flow paths in such an urban environment is difficult and you should probably not do this on a DTM where building areas have been filled by interpolation. Usually you do the flow path analysis in urban areas without sink filling to see where water accumulates. Since your dataset contains bridges that act as dams, sink filling can't be used. If you really require "valid" flow paths out of the raster you could try to use the "Breach Depressions" tool or the "Sink Removal" tool with...

Hi Jeroen, Thanks for sharing the information about the TouchTerrain website—looks like a really useful tool for generating 3D models from DEM data! For those who are exploring terrain modeling and 3D printing, I'd also recommend checking out Orca Slicer Download Now : https://orcasslicer.com/#download-orca-slicer ). It's a great slicer for preparing 3D models for printing, especially if you're working with detailed terrain models. The tool is designed to optimize the printing process, ensuring high-quality...

Manuel Waerder posted a comment on discussion User Forum
To prepare my DEM and derive flow paths, I want to smooth it using the “Fill sinks (Wang & Liu)” tool. However, in my 20 km² urban catchment area (elevation range 31.17–53.33 m), the tool modifies large parts of the DEM far too strongly. This happens regardless of the “Minimum Slope” parameter: Example 1: Minimum Slope = 0.1 → Fill_sinks − DEM = 0 to 8.53 m Example 2: Minimum Slope = 0.000001 → Fill_sinks − DEM = 0 to 6.68 m The figures attached show my original DEM and the result of Fill Sinks with...

Indeed :-). I wonder how the CRLFs came there in the first place, perhaps you could consider adding gittattributes file with eol setting. Thanks again! At MacPorts we have two patches for SAGA, needed to handle the environment of potential multiple Python and PostgreSQL living side by side. And every now and then, occasional patches are urgently needed because of e.g. updated dependencies, build environment (in particular compiler) and new OS versions (the latter often a challenge in general).

Hi Laurent, with Commit [3059d0] it is now possible to set / overwrite the flags. Best regards, Volker

That was an ugly commit [d2bbb8], but now all files should be consistently formatted.

Volker, I just noticed you reverted only one file. probably every file in repo need the same treatment.

Dear Sir : Thank you very much for your kind answer. I keep HPDF in /usr/local indeed : it works as this. Nevertheless, I found many months ago how to fix the "dylib not found" error, in particular with a Mac computer. It is because of CMake. In fact, after having read the Cmake documentation provided with Cmake (gui mode, or application), one may read that the rpath (or @rpath) is not automatic with Cmake, and/or Macos and CMake. I fix it, it works almost 100 %, and, as I have some time to write...

Hi, thanks for reporting and of course also for maintaining MacPorts of SAGA. This should be fixed by Commit [52c0da]. Best regards, Volker

It does the job. great help.

Hi, have a look at the Field Enumeration tool, it generates a unique identifier for each class. Best regards, Volker

Hi, I’m working with a polygon shapefile where each feature represents a distinct landcover class identified by a unique string attribute (e.g., Fr = Forest, BL = Barren Land, etc.). I intend to convert this shapefile into a raster grid using latest release of SAGA GUI. I understand that rasterization requires numeric class values, so I intend to create a new attribute field assigning integer codes to each class. However, I haven’t found a way to generate or assign these numeric values automatically...

Hi, I'm attempting to understand the implementation of the Plattner et al. (2006) wind sheltering index in SAGA via QGIS. Is it such that calling the windward method generates the exposure values (the negative values from Plattner et al.) while the calling the leeward method generates the sheltered values (positive values)? Selecting "Include negative slopes" will allow for the complete generation of the index with both positive and negative values? However, this particular option does not appear...
