DESCRIPTION
Process the content of a MTL file, as specified by document level1_dfcb_rev5_401.pdf
. See also http://landsathandbook.gsfc.nasa.gov/handbook/handbook_toc.html
FUNCTIONS
- landsat_meta_from_filename(FILENAME)
-
Returns information from the filename, like the PRODUCT_METADATA structured from the MTL record, but without opening the file.
- landsat_mtl_from_file(FILE)
-
Read one Vgroup record from the FILE, specified by name or filehandle.
Returned is a pair: the name of the record (for instance,
L1_METADATA_FILE
) and the destructed content. Each nested group is represented by a nested HASH.The HASHes contain keys in capitals, which are exactly the fields as found in the meta-data file. Additionally, a number of lower-cased keys are added (the lower cased versions of some upper-cased names) with smart processed information.
