-------------------------+--------------------------------------------------
Reporter: pcav | Owner: grass-dev@…
Type: defect | Status: new
Priority: normal | Milestone: 6.4.2
Component: Default | Version: 6.4.2 RCs
Keywords: | Platform: MSWindows XP
Cpu: Unspecified |
-------------------------+--------------------------------------------------
Commands like:
v.generalize input=province@Mapset_stefano type=area layer=1 -c
type=boundary method=douglas threshold=100000 look_ahead=7
reduction=50 slide=0.5 angle_thresh=3 degree_thresh=0
closeness_thresh=0 betweeness_thresh=0 alpha=1.0 beta=1.0 iterations=1
output=Province_general3
on Linux go well, whereas on windows some of the features are not
simplified: see
https://int.faunalia.it/~paolo/generalize.zip
for an example.

This may be related to different versions: 6.4.1 on Linux (good results),
6.4.2RC3 on Windows (bad results).

type=area ... type=boundary
...no good!
I agree that GRASS should complain but here I suppose that the
latter type "wins" and hence the generalization fails.
I tried with type=area only and it looks good.
Closing as user error, reopen if needed.
