Description
When I am exporting a cubefromshape result as a netcdf file the nodata value is -9999. This is not the value of the missing data which is typemin(Int32)+1 = -2147483647
I think, that the nodata value should be determined with help of the defaultval function.

Research direction
Start at the cubefromshape export path for NetCDF output and inspect how the missing-data value is selected, including the defaultval function. Reproduce an integer-layer export and verify that the NetCDF nodata value matches the missing-data value typemin(Int32)+1 rather than -9999.
