Hi!

Thanks a lot for your enthusiasm for improving the map. However, in order to avoid doing more harm than good, please start by taking small steps and by doing things you understand. As with many other things, there is a learning curve in OSM and it appears that you're trying to deal with things that you're lacking the necessary experience for. You severely risk putting off other mappers because they feel you're destroying the map, into which they have already put thousands of hours of voluntary work. 

For example:

1) With this changeset, you've mapped a lot of simple sidewalks and traffic islands as pedestrian areas. Have a look at the wiki. This is not what the highway=pedestrian tag is meant for.

2) You've destroyed connections that exist in the real world. For example, after your changes, routing engines cannot anymore route cyclists from Celovška cesta https://www.osm.org/way/1150942759 into Alešovčeva ulica https://www.osm.org/way/867882743 because of changed layout and persisting oneway tags.

Likewise for cyclists riding southbound https://www.osm.org/way/727578804 and wanting to turn into Na jami https://www.osm.org/way/986464720.

3) Before your change, the sidewalk ways were very precisely aligned to a high-resolution aerial imagery. Now, they are not anymore.

4) You’ve mapped a fictional road which is not physically separated from other roads https://www.osm.org/way/1152644580 . In OSM, we don’t map individual lanes (this is done via tags, not by mapping separate ways).


Your motivation and contribution is very much welcome. Eager mappers a desperately needed. But PLEASE PLEASE:

A) Don’t create huge changesets. Nobody will understand your intentions. Make small changesets and give these changesets meaningful comments, so others can understand what you’re trying to do.

B) Do only stuff that you understand.

C) Consult more experienced mappers or, even better, seek advice in the forum, in case you’re uncertain. https://community.openstreetmap.org

D) Keep in mind that OSM data is used for serious real-world applications like routing. A damaged map means that routers that rely on OSM data will deliver wrong results.

E) Run through OSM beginners’ guides and tutorials in order to get a rough idea of the basic workings.

If you have questions, please ask me or other mappers or the community forum https://community.openstreetmap.org. People are more than happy to help!

Happy mapping!
