Hi,
I basically need to get ALL the information about a .img (hfa) file
header and copy it into another .img (hfa) file I create with my own new
data. Can anyone help me as to what API's I should use and where to look for
them ? Any help is highly appreciated. Thank you.
Regards,
Anand

Reply-To: gdal-dev at remotesensing.org
Hi All
I am not sure if the following is a problem with GDAL
or my hdf4 library
With gdalinfo I constantly get
Driver: HDF4/Hierarchical Data Format Release 4
Size is 512, 512
Coordinate System is `'
Metadata:
....
GPOLYGONCONTAINER=-103.892405, -81.954139, -86.270138, -107.052668
^^^^^^^^^^^^^^^
GRINGPOINTLATITUDE=20.525827, 17.337449, -0.496254, 2.465055
GRINGPOINTSEQUENCENO=1, 2, 3, 4
the data for GRPOLYGONCONTAINER is I would expect for
GRINGPOINTLONGITUDE
Is anyone else seeing this ?
This is using Cygwin
Cheers
Norman

What HDF products used by you? What size of this datasets? If them has a
reasonable size, I want get the sample.

Hi Andrey
I am working with MODIS data
There are l2 and l3 data sets in the 'images' directory of
the MODIS Ocean Color tutorial
http://jeager.gsfc.nasa.gov/modis_workshop_unh/
I suggest that we use these as our 'standard' MODIS test files
Note I hope to eventually be able to duplicate the functionality of the
matlab and IDL code in this tutorial with GDAL and Python
Cheers
Norman

I have implemented such an option. Try "SUFFIX=ADD" with gdal_translate.
By default suffix will be replaced as previously.

Andrey, my first name is Alessandro :) and unfortunately i have no power to

i tryed both SUFFIX and INTERLEAVE, and found no problem :).
thanks a lot, this seriously cuts down the number of quirks i need to
implement in my apps!
i will stress test the ENVI driver from now on. if you need testing on
specific
areas (i.e. map_info), don't esitate to cc me directly.
cheers,
alessandro

Norman,
What GDAL version do you use?

Reply-To: gdal-dev at remotesensing.org
Is there any means to minimize the numbers of drivers
available in GDAL so that I can use it just to convert
from format "A" to format "B", I guess this way it
will be lighter weight. Can I do this? How?

If I remember correctly you are using MSVC
in which case I believe that you can modify the
$GDAL_SRC/frmts/makefile.vc EXTRAFLAGS variable
to just include the formats you want
ie this should yield a GDAL that only did tiff and bmp
EXTRAFLAGS = -DFRMT_gtiff -DFRMT_bmp
on Unix like systems you need to modify the
$GDAL_SRC/GDALmake.opt file variable $GDAL_FORMATS

Ayman,
Norman is right on this, though you can only control what gets
included by subdirectory of gdal/frmts, so for instance, to get any
driver in the frmts/raw directory you normally get them all. However, they
are "light". There are also a few dependencies between drivers that may
come
up.
I would add that you can save alot by not including the OGR drivers in a
GDAL
build where you only need raster support.
On windows set comment out the "INCLUDE_OGR_FRMTS" flag setting to disable
inclusino of OGR.
On Unix configure with the "--without-ogr" switch.
Best regards,

Norman,
I have fixed problem with HDF-EOS metadata parsing. You could check out
latest changes.
