[GRASS-dev] Invalid timestamp file for raster

[Sören Gebbert]

Hi Nikos,
the strategy that i use is to create an input file for t.register that
contains the raster names and the time stamps for registration:

map_name | start_time | end_time
...
...

In case of Landsat scenes, there are not end-time stamps. Create this
file while importing and fill it with map names and time stamps.

Use this file with t.register and register all maps in a STRDS that
have been imported. I would suggest to create a single STRDS for each
band, so you can use map algebra for computation.

Best regards
Sören
