mdekauwe / extract_MODIS_HDF.py

Created May 19, 2010 13:31

	#!/usr/bin/env python
	"""
	Code extracts MODIS derived products (1km) from the HDF, rescales them, checks values against
	acceptable QA and outputs to a binary file. Code seems generic enough that one can just
	add another method for a new MODIS product. Currently works on LAI, NDVI/EVI and LST. Code
	also writes out an ENVI .hdr file...nice.

	*** NOTE...I don't vouch for the reliability of the default QA, please supply your own on
	the cmd line.
