Hi Johan,
Just use CPL_VSIL_ZIP_ALLOWED_EXTENSIONS to add new extension and enjoy.
CPLSetConfigOption(CPL_VSIL_ZIP_ALLOWED_EXTENSIONS, "sg-grd-z");
Or in ogrinfo use option -config CPL_VSIL_ZIP_ALLOWED_EXTENSIONS sg-grd-z
Best regards,
Dmitry

Hi all,
Saga GIS introduced a new file format .sg-grd-z [1] which actually is
a zipfile containing the normal files encountered in saga gis (*.sgrd
; *.sdat; and optionally *.mgrd ).
In fact, if you rename the .sg-grd-z file you can already open it using vsizip
eg
cp Landgebruik_def_watem.sg-grd-z Landgebruik_def_watem.zip
gdalinfo /vsizip/Landgebruik_def_watem.zip/Landgebruik_def_watem.sdat
Driver: SAGA/SAGA GIS Binary Grid (.sdat)
Files: /vsizip/Landgebruik_def_watem.zip/Landgebruik_def_watem.sdat
/vsizip/Landgebruik_def_watem.zip/Landgebruik_def_watem.sdat.aux.xml
/vsizip/Landgebruik_def_watem.zip/Landgebruik_def_watem.sgrd
/vsizip/Landgebruik_def_watem.zip/Landgebruik_def_watem.prj
Size is 49400, 24000
Coordinate System is `'

Center ( 140500.000, 189995.000)
Band 1 Block=49400x1 Type=Int16, ColorInterp=Undefined
NoData Value=-32767
I'm willing to get my hands dirty to add support for this format in
gdal (either developing/testing/...), but I wonder if there are any
similar formats where I can find inspiration.
Kind Regards,
Johan
