Hi yhhu, Unfortunately the MGET HDF conversion tool can only convert 2D HDF
variables. You are the third person to inquire about this in the past few
months. The last person had some success converting the HDF file to a NetCDF
file and then working with it in ArcGIS using the Multidimension Tools. I am
not sure what she used to convert the HDF to NetCDF, but you can probably find
a solution quickly by searching the internet on that. Alternatively, if you are skilled at Python programming, it would
not be too difficult to write a script that could do the conversion. The script
would use the pyhdf Python package or GDAL Python bindings to read 2D slices of
the 3D HDF variable and then call an MGET function to convert each 2D slice to an
ArcGIS raster. If you have some programming skills, we could talk more about
this. Finally, because there seems to be a demand for this, we are
considering implementing a multi-dimension HDF conversion tool in a future
version of MGET. This would not be available for several months, at minimum. Best regards, Jason From: huyh
[mailto:] Hi, MGET is great for
handling 2 dimension data, but I couldn't use it to convert multiple dimension
data, such as CERES, MISR HDF data used in climate change research, to tif
format. These data usually have more than 3 dimension variables like
longitude, latitude, pressure and variables. So I want to know if MGET can do
this job? Thank you very
much! regards, yhhu 2009-03-31
