[GRASS-dev] v.in.osm

[Štěpán Turek]

Hi,




I incline to clean up the data as a default. The module should behave in a 
user-friendly way therefore expected behavior should be the default one.




I guess that most users would expect to import the data in topologically 
correct format. If the topology is wrong, a user can get totally misleading 
results (wrongly assuming they are correct) from various vector modules 
which is not very nice.

I would not make it the default. You cannot be sure that users want to 
clean in the same way you do, so better to provide it as an 
(well-documented) option.
