[GRASS-user] Interpreting r.watershed accumulation map

[Laurent C.]

Hello Sören,

The problem occurs when Itzï is calling:
"tgis.SpaceTimeRasterDataset(name).is_in_db()"

tgis.init() is called just before. "name" is a a formatted map or
strds ID (i.e including mapset)

It is difficult to understand what is happening because I can't
reproduce the problem.

Regards,
Laurent
