The article actually breaks down the exact lacunae in Apple's approach - it's certainly has more map domain specific insight than all the other articles on iOS6 Maps put together. And it has recommendations which are very specific and not hand-wavy. From the article 1. Completeness – Features are absent and some features that are included seem to have erroneous attributes and relationships. 2. Logical Consistency - Expecting the data across different sources to be completely consistent ie 'An example of this could be having a store’s name, street number and street name correct, but mapping it in the wrong place' 3. Positional Accuracy – is considered the closeness of a coordinate value to values accepted as being true 4. Temporal Accuracy – particularly in respect to temporal validity – are the features that they map still in existence today? 5. Thematic Accuracy – particularly in respect to non-quantitative attribute correctness and classification correctness.
