An easy-to-use Android app that lets anyone contribute to OpenStreetMap by answering simple questions on location.
StreetComplete is an Android application that simplifies contributing to OpenStreetMap by turning map editing into a series of simple, location-based questions. It automatically identifies missing map data nearby and allows users to fill in details—like road names or business hours—through an intuitive Q&A interface, with edits uploaded directly to OSM. The app is designed for offline use, making it ideal for on-site surveys.
Android users interested in improving OpenStreetMap data without technical expertise, including casual mappers, local community volunteers, and field surveyors.
It uniquely lowers the barrier to OpenStreetMap contribution by eliminating the need to learn OSM's complex tagging system, offering a gamified, question-driven workflow that works offline and is accessible to complete beginners.
Easy to use OpenStreetMap editor for Android
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Explicitly designed for users with no OpenStreetMap expertise, as the README states it 'can be used without any OpenStreetMap-specific knowledge.'
Built for field surveys with economic data usage, allowing contributions without an internet connection, as highlighted in the description.
Automatically generates nearby quests for missing map data, transforming editing into an engaging, location-based activity with interactive markers.
Answers are processed and uploaded as meaningful changesets directly to OpenStreetMap, streamlining the contribution process without manual intervention.
Available only on Android, with iOS support still in development per sponsorship notes, limiting accessibility for a significant portion of mobile users.
Quests are restricted to simple questions answerable on-site, which excludes advanced mapping tasks like custom tagging or complex geometry edits.
New quests and improvements depend on community contributions and external funding, as seen in the sponsors section, potentially slowing down feature updates.
