Building Location-Aware Apps using Open Source (AnDevCon SF 2014)
0 likes725 views
The document outlines the process of building location-aware applications using open source technologies and open data. It provides an agenda that includes topics such as mapping applications, geolocation services, and the integration of various open data sources like OpenStreetMap and Pelias for geocoding and routing. The presentation emphasizes the benefits of open source, including transparency and flexibility, while also providing practical examples and exercises for developers in creating such applications.
