Start with local government content, add a dash of commercial navigation, a pinch of OSM, and wa-lah! You’ve got a recipe for creating the best in breed of authoritative maps. Simple? Not a chance. If your goal is to create beautiful, complete, and authoritative maps that describe essential data layers, using disparate sources is often required.
This session will discuss issues for achieving this goal - data quality assessment, metaphors for contribution, handling imports and data conflicts, and licensing paradigms. Christine will discuss the Esri Community Maps program, its results from a recent assessment of integrating OSM data into Community Maps, and ways OSM and Community Maps can learn from and benefit one another in the near future.
