The Mapbox data team is always exploring ways to improve our workflow for resolving OpenStreetMap issues with the Java OpenStreetMap Editor (JOSM). Over time, we have found techniques that increase our productivity. We work on multiple windows while we download or upload data, and we use a gaming mouse that’s configured to JOSM shortcuts to speed up repetitive actions. We can download data or draw buildings with just a few clicks.


Tasks like fixing unconnected or crossing can be worked on in up to 6 windows.

The techniques described above, in addition to our mapping guides, allow our data team to resolve thousands of OpenStreetMap issues every day with high quality and productivity.
