[GRASS-dev] v.in.osm

Hi,

I did a change in v.in.osm adding a c flag to cleanup the data and
create a GRASS GIS network topological correct, this is done by
default now. I attached a diff.

The flag could be also the opposite, so don't cleanup the data.

What do you think?

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.

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.
