[GRASS-user] r.hants and r.series.lwr in Windows

[Helmut Kudrnovsky]

>I am trying to establish a workflow to gapfill temporal maps using r.hants

>The issue I am encountering is that both r.hants and r.series.lwr are

trying here with:

-------------

r.series.lwr -l -h -i input=ETact_SEBAL_2019_03_mm_month at TMPMAP,ETact_SEBAL_2019_04_mm_month at TMPMAP,ETact_SEBAL_2019_05_mm_month at TMPMAP,ETact_SEBAL_2019_06_mm_month at TMPMAP,ETact_SEBAL_2019_07_mm_month at TMPMAP,ETact_SEBAL_2019_08_mm_month at TMPMAP,ETact_SEBAL_2019_09_mm_month at TMPMAP,ETact_SEBAL_2019_10_mm_month at TMPMAP,ETact_SEBAL_2019_11_mm_month at TMPMAP order=2 fet=0.5 dod=3 range=0,10000000000000000000000000000000000000 maxgap=3

------------

r.univar map=ETact_SEBAL_2019_03_mm_month_lwr at TMPMAP
total null and non-null cells: 10413
total null cells: 417
Of the non-null cells:

range: 78.5551

the issue is here in your original command:

range=0,inf

winGRASS doesn't recognize inf or INF as infinity.

there is somewhere an old ticket in trac. please open an issue in github for this.

kind regards
