[GRASS-user] fill gaps

[Martin Landa]

Hi all,

I am doing some post-classification smoothing. First areas lesser than
1ha are removed using `r.reclass.area` and then gaps (NULL cells)
filled using `r.filldir`. My region

rows:       977
cols:       1227
cells:      1198779

number of NULL cells to be filled

total null and non-null cells: 1198779
total null cells: 120560

Unfortunately `r.filldir` is taking ages in GRASS 6. Is there other
quicker way how to fill gaps (in GRASS 6)?

Thanks in advance, Martin
