[GRASS-dev] t.rast.mapcalc: The temporal map type of the sample dataset must be interval

[Martin Landa]

Hi,

I have two spatial-temporal dataset which are equal (time POV):

$ t.rast.list tp5
clip_LT51910261987057XXX02_B5|pisek_tabor|1987-02-26 09:12:36|None
clip_LT51910262004152KIS00_B5|pisek_tabor|2004-05-31 09:32:23|None
clip_LT51910262004200KIS00_B5|pisek_tabor|2004-07-18 09:33:46|None
...

$ t.rast.list tp2
...
clip_LT51910261987057XXX02_B2|pisek_tabor|1987-02-26 09:12:36|None
clip_LT51910262004152KIS00_B2|pisek_tabor|2004-05-31 09:32:23|None
clip_LT51910262004200KIS00_B2|pisek_tabor|2004-07-18 09:33:46|None

$ t.rast.mapcalc in=tp2,tp5 exp="tp5 < 40 || tp2 < 40" out=water
basename=water --o
ERROR: The temporal map type of the sample dataset must be interval
No samples found for map calculation

Why the dataset must be interval? I mean start time and end time
(which is None) are equal. Thanks for explanation, Martin
