I work for a privately owned park which is open to the public. The park is already listed on OSM but the current boundaries are wildly incorrect. I really have no idea how to edit these boundaries. I have access to GIS files of our boundaries in various formats (KMZ, JSON, etc). I am just not sure how to take these files and use them to update or replace the current park boundaries. Thank you.

Editing park boundaries can be a daunting task for a newbie because often what is the outer boundary of the park, is also another boundary - maybe that of a neighbouring residential or agricultural area, a different park, or sometimes also an administrative boundary. In these cases we prefer to have the actual geometry recorded only once (so that, if you change the park boundary, you automatically change the neighbouring boundary, rather than creating an overlap or a no-man's-land in between the two areas).

This is often done using a construct called a "relation" which is made up of several "ways", and different relations can have shared use of the same "way".

It might be easiest if you just made the KMZ or JSON file available somewhere for download and then pinged the community on asking if someone nearby would mind taking this on. While we're always happy to welcome new mappers, if the first thing you try is edit a park boundary, you're likely to break things ;)

This all makes sense - I certainly don't want to break anything.

Is posting in the community similar to leaving a note directly on OSM? I posted a note about a month ago on the current park stating the boundaries are wrong and to contact me for the file. I don't want to overdo it by also creating a post in the community. Thanks!
