#527: Broken io_gdal raster import in SAGA LTR package shipped with OSGeo4W
-------------------+---------------------------
Reporter: lutra | Owner: osgeo4w-dev@…
Type: defect | Status: new
Priority: major | Component: Package
Version: | Keywords:
-------------------+---------------------------
1) In OSGeo4w installer the option for SAGA LTR says "2.3.1", but once
installed "saga_cmd" says 2.3.2, which is weird per se as SAGA 2.3.2 does
not exist:
https://sourceforge.net/projects/saga-gis/files/SAGA%20-%202.3/
2) if launching SAGA GUI of this SAGA installation it apparently seems all
ok, but for instance it misses the "Import > GDAL/OGR" tools which are
available in any older and newer (or even the same) versions downloaded
from SAGA site. This could be related to the next point, that is the more
important
3) In this OSGEo4W SAGA LTR install the raster import operation (done with
the "io_gdal" module) produces a WRONG raster, where 1 are replaced with
NULLs. This DOES NOT happen in any older and newer (or even the same)
versions downloaded from SAGA site. This is of course a deal breaker for
Processing because it calls io_gdal any time a SAGA raster tool is used
You can test with this input

and this command
saga_cmd io_gdal 0 -TRANSFORM 1 -RESAMPLING 0 -GRIDS
"imported_raster.sgrd" -FILES "bacias_lee_2014_2018_17_Binary.tif"
