Hi Thorsten (Shernott)

In any case, before you loose motivation: How about doing some
micromapping meanwhile :->? Looking closer to western Lausanne I see
quite some "white areas" when retrieving p.ex. post_boxes with "my"
And I didn't check cycle_barriers, bicycle_rentals, viewpoints,
picnic_sites, fireplaces, leisure elements, toilets, post_box(es) or
Now seriously: As I already tried to hint in my answer to Stéphane, I
think you are closer to the "OSM way" of mapping. But that's from a
If we would have an association, I think it would be easier to
"mediate" such (fortunately rare) cases. By chance, there will be
probably an OSM meeting in Zurich next week (OSM-Treffen
) where young mappers and "distinguished elderly IT guys" (like Simon
and I :->) sometimes meet. If you wish, I could put the issue on the
"agenda" the and get some general/spectrum of opinion?

>> Modification de Shernott http://www.openstreetmap.org/browse/changeset/9065948
> Ok, it looks like we have to keep arguing, so let's shift the focus from the Bois du Jorat (which was my main concern) down to the city of Lausanne. After a quick glance on the change set proposed by Stéphane, I am not sure if it does tell the whole story. Since I don't like it when entire forests disappear for days, I tend to work with incremental change sets that leave the data intact and valid after each change. I was doing a bit more around the place de la Riponne than just changing the Riponne multipolygon, and I am not sure if it is all contained in this change set.
> The Place de la Riponne is a pedestrian multipolygon with pedestrian highways inside linking several points relevant for pedestrian routing. There is a new subway station with entrances from Place de la Riponne on the upper level and Place Arlaud (northeast of "Theatre Bulimie") on the lower level, so a couple of things have changed, which were not mapped yet.
> What I changed there:
> * Added an angle to the stairs from Riponne to Arlaud to represent their correct shape (they are actually old and well enough visible on the available aerial images)
> * Added stairs and pedestrian ways around the Place Arlaud to reflect the different levels there.
> * Added stairs, entrances and passages to and through the new subway station (in a simplified manner)
> * Removed stairs and pedestrian ways that don't exist anymore.
> * Updated the pedestrian highways linking the relevant points of the Riponne, so that they are useful for pedestrian routing again.
> * Aligned those pedestrian highways for more orderly rendering on Maps who show them instead of the pedestrian multipolygon or who show both. (Those pedestrian highways are arbitrary anyway, it's a place after all.)
> * And yes, I am guilty of extending the shape of the Place de la Riponne multipolygon to some highways that are its physical boundaries while leaving the way with the nodes of the old boundary around, just in case somebody should wish to change it back - which Stéphane promptly did.
> While we are at it, I could mention that I added a little meadow and forest between Av. de Riant-Mont and Rue du Tunnel, whose absence on the map didn't seem to bother Stéphane despite its visibility on aerial imagery. But as soon as it was there, he had to correct its boundaries (I used Av de Riant-Mont to separate the meadow from the residential area, which didn't suit Stéphane):
> And I could mention that I added a little park with playground, parking space and ball sport area between Rue du Nord and Rue César-Roux, whose absence on the map didn't seem to bother Stéphane either despite its visibility on aerial imagery. But again, as soon as it was there, he had to correct its shape and boundaries and to add an inexistent wall (which I removed subsequently):
> Do we really need to dig out all the change sets? Frankly, while I don't feel much motivation to map in Lausanne anymore, I feel even less motivation to dig up all the change sets and to argue about them. If my mapping in and around Lausanne sucks so badly that it needs constant surveillance and instant interventions and corrections, well, then I better put my time to a more worthwhile and productive use. Which is the conclusion to which I came already a week ago.
