[gdal-dev] HDF4 extrac lat/lon subdatasets...

[Mario Cavicchi]

Hi All,
I must extract from a HDF MOD03 file the subdatasets of latitude and
longitude. if I open the image with ENVI, in the list of subdatasets, I
read this list:

Latitude
Longitude
Height
SensorZenith
SensorAzimuth
Range
SolarZenith
SolarAzimuth
Land/SeaMask
gflags

instead the command gdalinfo shows this list of subdatasets:

Subdatasets:

SUBDATASET_1_NAME=HDF4_EOS:EOS_SWATH:"MOD03.A2006159.1045.005.2008113013452.hdf":MODIS_Swath_Type_GEO:Height
  SUBDATASET_1_DESC=[2030x1354] Height MODIS_Swath_Type_GEO (16-bit integer)
SUBDATASET_2_NAME=HDF4_EOS:EOS_SWATH:"MOD03.A2006159.1045.005.2008113013452.hdf":MODIS_Swath_Type_GEO:SensorZenith
  SUBDATASET_2_DESC=[2030x1354] SensorZenith MODIS_Swath_Type_GEO
(16-bit integer)
SUBDATASET_3_NAME=HDF4_EOS:EOS_SWATH:"MOD03.A2006159.1045.005.2008113013452.hdf":MODIS_Swath_Type_GEO:SensorAzimuth
  SUBDATASET_3_DESC=[2030x1354] SensorAzimuth MODIS_Swath_Type_GEO
(16-bit integer)
SUBDATASET_4_NAME=HDF4_EOS:EOS_SWATH:"MOD03.A2006159.1045.005.2008113013452.hdf":MODIS_Swath_Type_GEO:Range
  SUBDATASET_4_DESC=[2030x1354] Range MODIS_Swath_Type_GEO (16-bit
unsigned integer)
SUBDATASET_5_NAME=HDF4_EOS:EOS_SWATH:"MOD03.A2006159.1045.005.2008113013452.hdf":MODIS_Swath_Type_GEO:SolarZenith
  SUBDATASET_5_DESC=[2030x1354] SolarZenith MODIS_Swath_Type_GEO (16-bit
integer)
SUBDATASET_6_NAME=HDF4_EOS:EOS_SWATH:"MOD03.A2006159.1045.005.2008113013452.hdf":MODIS_Swath_Type_GEO:SolarAzimuth
  SUBDATASET_6_DESC=[2030x1354] SolarAzimuth MODIS_Swath_Type_GEO
(16-bit integer)
SUBDATASET_7_NAME=HDF4_EOS:EOS_SWATH:"MOD03.A2006159.1045.005.2008113013452.hdf":MODIS_Swath_Type_GEO:Land/SeaMask
  SUBDATASET_7_DESC=[2030x1354] Land/SeaMask MODIS_Swath_Type_GEO (8-bit
unsigned integer)
SUBDATASET_8_NAME=HDF4_EOS:EOS_SWATH:"MOD03.A2006159.1045.005.2008113013452.hdf":MODIS_Swath_Type_GEO:gflags
  SUBDATASET_8_DESC=[2030x1354] gflags MODIS_Swath_Type_GEO (8-bit
unsigned integer)

How I can get the first and the second dataset?

Thanks to all. Regards.
