[Qgis-user] Processing tool GDAL Grid (Nearest Neighbor) with unreachable additional options in GUI

[Stefan Keller]

Hi,

I'm using QGIS 3.6.1-noosa and I want to use the processing tool "GDAL
Grid (Nearest Neighbor)" GUI in order to call gdal_grid as follows:

gdal_grid -a nearest:radius1=1:radius2=1:nodata=-99 \
    -txe 50 350 -tye 650 450 -outsize 3 2 -zfield z \
    "grid in.gpkg" "grid out.tif"

There are two issues here:

1. The options "-txe 50 350 -tye 650 450 -outsize 3 2" are unreachable
in GUI. Using GUI section "Additional generation options [optional]"
generates wrong options "-co txe -co 50 -co 350 -co tye -co 650 -co
450 -co outsize -co 3 -co 2".

2. In and out file names are not enclosed by parantheses,

What can I do (except calling gdal_grid from command line, which is OK
for myself but not for end users)?
