I tried to compare variable definitions in the landsat_met.c file with the diff
"TLold.txt_VS_MTL.txt" file (metadata that correspond to a LT5 scene). The
differences I see are the following:
- SPACECRAFT_ID: was Landsat5, is: LANDSAT_5
- SENSOR_ID: *this is the same*
- ACQUISITION_DATE: renamed (?) to "DATE_ACQUIRED"
- CREATION_TIME: was (?) PRODUCT_CREATION_TIME, is: FILE_DATE
- SUN_ELEVATION: was not existing (!), is: same
- BAND%_GAIN: nowhere to be found as is, was (?):
CORRECTION_METHOD_GAIN_BAND%, is: CORRECTION_GAIN_BAND_%
- LMAX_BAND%: renamed to RADIANCE_MAXIMUM_BAND_%
- LMIN_BAND%: same as above, renamed to RADIANCE_MINIMUM_BAND_%
- QCALMAX_BAND%: renamed to QUANTIZE_CAL_MAX_BAND_%
- QCALMIN_BAND: same as above, renamed to QUANTIZE_CAL_MIN_BAND_%
Is this enough to get i.landsat.toar working?
Thanks, Nikos
