I was recently introduced to Steve Gifford at Mousebird Consulting, a software firm based in San Francisco that builds mapping tools for the iOS platform. Steve and his colleagues are the developers of the open source iOS mapping framework, WhirlyGlobe Maply. The framework enables them to build both 2D and 3D mapping applications for iPhones and iPads. It’s slick, impressive technology that is sort of a combination of the Google Earth globe and a conventional, web-based mapping application.
Mousebird Consulting joined the LocationTech working group at the Eclipse Foundation in March. LocationTech is a young organization and while there are now several projects moving through the incubation process (GeoTrellis is one of them), there is not yet a lot of coordination or integration between projects. So I was really excited to see Steve take the initiative to integrate one of our GeoTrellis examples, the GeoTrellis Transit API demo, into Mousebird’s WhirlyViz application. GeoTrellis Transit is an extension of the core GeoTrellis framework.
GeoTrellis Transit uses OpenStreetMap and a GTFS file to enable generation of “travel-sheds”. This one shows walking distance are around downtown.
The accessible area changes a great deal when we add access to regional rail.
