[Geowanking] GIS API for iPhone?

[David Fawcett]

This is more of an app that can consume OGC services instead of an
API, but James reviews iExtMap here:

They show a demo app that consumes a gdal-generated tile-cache (stored on the device) and shows it on top of Google's tiles in a standard MKMapView, so the MapKit Framework can be used to control overlaying vector data on top it it, just like Google Maps. The complete code for the app is in the WWDC demo code package that is unfortunately only available to registered iPhone developers. It does not look like it made it into the non NDA'd MapKit samples like the other demos from the talk.
