[gdal-dev] reproject python numpy binary swath/lat/lon

[David Hoese]

I have 3 binary files, the image/swath 2D data and the corresponding 2D 
latitude and longitude pixel data from a previous processing step.  The 
binary files were all created using numpy's tofile().  I would like to 
take the binary data (as filenames or loaded into numpy arrays) and 
remap it to a grid that I can define with PROJ.4 parameters and output 
the remapped data as another binary file or numpy array.  I would like 
to be able to do this all from within python if possible without any 
command line calls.  I found this thread that describes a solution that 
looks like what I'm trying to do at least to start with, but suggests 
gdalwarp from the command line:

I'm new to GDAL and pretty new to remapping in general.  Is what I'm 
trying to do possible with GDAL?  Where should I start?  I'm coming from 
using a remapping utility that had one purpose and I'm kind of getting 
lost in all of the options GDAL offers.

Thanks for any help.
