I am trying to run the saga fill sinks (wang &liu) but it always results in following error "'NoneType' object has no attribute 'crs' See log for more details". I am using QGIS 2.18.12. I am running this algorithm inside QGIS.

I do not know what i am doing wrong

Raster CRS is "+proj=utm +zone=43 +datum=WGS84 +units=m +no_defs". I have projected it before running the fill sink(wang & liu).

  • 'crs' is the acronym of Coordinate Reference System. Does your raster have this attribute? Check on properties window, if not, define projection to solve this issue

  • are you running this from inside QGIS (using Processing)? Have you tried the equivalent command (saga_cmd) from a terminal (osgeo4w shell on Windows), or from the saga gui? Also what version of QGIS?

  • If you are using standalone QGIS, is it possible to update it to QGIS 2.18.14? I think SAGA 2.3.2 is better aligned with 2.18.14. Or, if you need to stay with QGIS 2.18.12, SAGA 2.1.2 - 2.1.4 would be safer.
