[GRASS-dev] [GRASS-user] i.landsat.toar unable to read metadata file

Nikos_Alexandris · December 13, 2012, 6:45am

Nikos:

I tested the modified landsat_met.c code, provided by E. Jorge Tizado. It
works! Yet, it fails somewhere else, e.g.:

--%<---
# get toar
i.landsat.toar input_prefix=${BASE} output_prefix=${BASE}_toar
metfile=${BASE}_MTL.txt

ERROR: Unknown production date (defined by 'product_date')
--->%--

It seems there are several modifications to the MET content structure.
Fortunately (?) two MET files are provided *currently* (at least I have seen
this in several L[MTE][457] scenes.

For example, an LT5 packed scene contains:
..
LT51810332008141MTI00_MTL.txt
LT51810332008141MTI00_MTLold.txt
..

Sorry,

The diff file...

is better read like:

After checking the *current* MTL.txt files along with the landsat_met.c code,
it seems that there is one unified MTL.txt file for all sensors now, right?

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

Try to add an additional strcmp() case where ACQUISITION_DATE is
changed to DATE_ACQUIRED

sorry I am very busy these few coming days...

The original changes I got from Jorge I attach again. Should they be
submitted to SVN?

Jorge did some more changes, I tested and verified that it works with both L5's and L7's along with a new(er) MLT.txt metadata file. Jorge, could you please resend it?

Nikos

ps- due to an hdd failure I lost some stuff (2 weeks of e-mails and data missing from my latest sync because I was non-stop moving these days) so I can't attach the latest i.landsat.toar right now (need to get my hdd fixed first).

neteler · February 2, 2013, 6:47pm

Hi all,

I have finally updated the SVN (GRASS 6.4, 6.5 and 7) with the updated
version of i.landsat.toar. Please test.

Best
Markus

Hi all,

I got thermal band fixes from Jorge and applied them to GRASS 6.4.svn
and 6.5.svn.
http://trac.osgeo.org/grass/changeset/55376

They still need to be fwd-ported to GRASS 7.

I guess this is the fix related to the post entitled

"i.landsat.toar fails to convert DNs (bands 61 and 62) to temperature for
Landsat 7 scene"

Works in G64 -- tested with an L5 (LT51820362009326MTI00) and an L7
(LE71840312002041SGS00) scene.

Thank you, Nikos

and 6.5.svn.
