Vespucci is an advanced open source tool for editing OpenStreetMap data, it is not a map viewer or a navigation app. You will need an OpenStreetMap account to use it . You can download the map data for a specific area and edit the map. After editing, you can upload it directly to the OSM servers. Any accidental change can be undone and all changes are listed for review before upload. Tag-autocompletion, JOSM compatible presets, links to the translated map-features pages and even auto-completing nearby street names help to find the right tags to use. We recommend disabling auto-updates for Vespucci so that you can upload your edits before app updates. More information and documentation can be found on vespucci.io and in the on-device help. Please do not report problems here or ask for support, see why we can't provide support and accept issues on the play store review section. You can report issues directly from the app without a github account or go directly to the issue tracker.
