Altus Mapping Engine 1.0

The BA3 Mapping Engine is a high-performance library designed for iOS developers who are creating both simple and demanding mapping apps for iPhones and iPads. Developers using things like MapKit and Route-Me generally run into performance, capacity or feature walls that block development, and the BA3 Mapping Engine can eliminate those walls.

You can learn about the features and performance of the BA3 Mapping Engine by visiting this BA3 Mapping Engine description. On that same page you can also download a free copy of the Mapping Engine SDK along with a detailed reference app. This reference app exercises all of the major features of the BA3 Mapping Engine and contains a wealth of sample code. You can see the reference app in action in the video found on the videos page
