Open source mapping and GIS has been exploding onto the tech scene in the past year. Combined with the equally explosive growth of powerful mobile platforms, a need is arising for rich, offline-capable mobile mapping technologies. This presentation will focus on a process for taking open data sources, turning them into beautiful custom maps, using them on mobile in an offline-capable way, and doing it all with entirely open source code. Attendees should expect to gain understanding of this process, the open source tools available for their use, and potential problems faced when mapping on mobile.
