I recently noticed that OSM does not include the most recently updated versions of the national parks in Utah. I've taken it upon myself to fix this, and I've made up a shapefile from the state governments website. I'm fairly new to OSM editing, but from what I can tell, there isn't really a good tool for really low zoom edits - fixing boundaries this large seems hard.

What is an approach for this?

You can use JOSM.

You don't have to download the full area which might be just too large in your case. If you know the ID of the boundary relation then go to File -> Download object, select relation, paste the ID and make sure you have selected to download referrers (parent relations) and relation members, too.

If you like you can still download additional areas later on via the usual way File -> Download data.


The way that I would do this, as someone with an ArcGIS Desktop license, is to use the ArcGIS Editor for OpenStreetMap:

ArcGIS Editor for OpenStreetMap (OSM Editor) is a free, open-source add-on for ArcMap that helps you take advantage of the OpenStreetMap (OSM) dataset and become an active member of the growing OSM community.

It downloads an area of OpenStreetMap (which can be large) into a file geodatabase, where you can edit it using the editing tools of ArcGIS Desktop, and then post the changes back to OpenStreetMap.


Editing in large volume with every detail possible is done through the Java OpenStreetMap editor or JOSM. But since you are updating the old boundaries which have links to other data, editing might cause undesired consequences.
