I am using Qgis 2.1 ver. 5f5cd4c (64 bit version on win7 64) OSGeo installed. I was trying to reclassify a DEM in EPSG:32614. I used the SAGA's Reclassify algorithm in the processing toolbox. I defined that I wanted to use a simple table, defined the table and that I wanted the reclassified grid saved to a tif file. I also wanted the resulted reclassified DEM to be opened after the algorithm finished the calculations. This is what I am repeatedly getting:

I tried to open a new project and load the resulting raster manually, but Qgis does not recognize it as a valid raster data source:

I was able to open the file and convert it to GeoTIFF in SAGA. I wonder if I am missing something in the reclassifying procedure, or something related with the format of the resulting raster. Thanks in advance for any advice.

PS. I was able to use r.reclass to do what I wanted. I also tested the saga reclasify algorithm in other two installations and I have the same problem.

  • Did you find a solution? I am having some problems with QGIS 2.18.12 saving the results to a permanent file. It works with a temporary file. I reported it as a bug here: issues.qgis.org/issues/17080#change-81836, but it seems it can't be reproduced. – Ernesto561 Sep 3 '17 at 15:41
  • The only solution is to reclasify the raster using r.reclass in the processing toolbox. check this: gis.stackexchange.com/questions/121532/… – Gerardo Jimenez Sep 4 '17 at 13:16
  • Thanks. The SAGA Reclassify tool is more user friendly, but it seems there are still some bugs. I'll use only r.reclass. – Ernesto561 Sep 4 '17 at 14:37
