Dear all,
I'm trying to import HDF (v4) files on R2.6.2 using the package rgdal
and FWTools v2.1.0. I have the following message :
> GDALinfo("T20060012006008.L3m_8D_SST_9.hdf")
Erreur dans .local(.Object, ...) :
GDAL Error 4: `T20060012006008.L3m_8D_SST_9.hdf' not recognised
as a supported file format.
I can load this file with FWTools without problem.
I suppose that rgdal is not able to recognize the path to the
FWTools/bin directory:
> library(rgdal)
Le chargement a nécessité le package : sp
Geospatial Data Abstraction Library extensions to R successfully loaded
Loaded GDAL runtime: GDAL 1.5.0, released 2007/12/18
GDAL_DATA: C:/PROGRA~1/R/R-26~1.2/library/rgdal/gdal ####### it should
be FWTools/bin ?? #####
Loaded PROJ.4 runtime: Rel. 4.6.0, 21 Dec 2007
PROJ_LIB: C:/PROGRA~1/R/R-26~1.2/library/rgdal/proj
However I set before the PATH environment variable in Windows
(Start>Parameters>Configuration Panel>System>Advanced>Environment
variables : GDAL_DATA set to C:\Program Files\FWTools2.1.0\bin) as
explained in http://rgdal.sourceforge.net/. No effect.
What's wrong ? Is there a thing that I've missed or didn't do correctly?
Is there another way to set this directory?
Thank you for your help^.
David
