[PATCH] five dimensional file image access fails for some dimensions

Reported by: warmerdam Owned by: warmerdam
Priority: normal Milestone:
Component: GDAL_Raster Version: svn-trunk
Severity: normal Keywords: netcdf
Cc: mdsumner, dnadeau

Description

Attempts to read image data from bands 5 to 8 in the file:

​http://staff.acecrc.org.au/~mdsumner/gdal/foo.nc

results in errors like: 

ERROR 1: netCDF scanline fetch failed: Index exceeds dimension bound
ERROR 1: IReadBlock failed at X offset 0, Y offset 0
ERROR 1: netCDF scanline fetch failed: Index exceeds dimension bound
ERROR 1: IReadBlock failed at X offset 0, Y offset 1

and all imagery comes back zeros.

I tested with trunk.

I uploaded a patch to fix this. It allows this file and other 5D and above NetCDF files to be read correctly.

I uploaded an R example to generate a file for testing.
