Subject: r.in.gdal: writing map timestamp (wish)
grass downloaded at: CVS Server, Germany
grass sources source: yes, I am using the latest GRASS from CVS
Hi again,
a wish for r.in.gdal: It would be great if the map timestamp
would be written (see r.timestamp for coding).
There is a real need to keep the timestamp for maps, especially
in terms of multitemporal analysis. Since GRASS already provides
the DateTime library, we should use this feature for as much
modules as possible. However, it starts with the data import.
At least remote sensing image formats usually contain the
timestamp which is already extracted by the GDAL lib.
Thank in advance,
Markus

Markus,
I assume you wish that the original acquisition date of the scene would
be preserved, is that right?
Currently there is no standardized way this is handled in GDAL. It happens
to be captured in the metadata of some formats, such as CEOS, but not
in an organized way that an application could check for without having alot
of format specific rules.
I will take your suggestion under consideration for GDAL. Let me know if I
have missed your point.
