SIRpy
======

Description
===========
A library of Python utilities for loading and displaying BYU .SIR file format 
data.  Includes some examples.

The code is general python.  It is a very simple translation of the SIR code
and is not intended to be very sophisticated.  For example much better 
schemes for storing the SIR header could be used.

Key files:
 sir_io.py -- scripts for reading sir files, extracting header values, printing
 sir_geom.py -- scripts for doing geometric transformations of sir file pixels
                using header information, e.e. pix2latlon, latlon2pix
 showsir.py -- displays contents of sir file
 printsirhead.py -- prints header of sir file
 sirresize.py -- resizes sir files
 plot_latlon_box.py -- illustrates plotting locations on display image
