Poor vetting and coordination of 3rd party supplied data on the Apple Maps system side (duplicates, missing localization, etc.) with no viable way to report many kinds of errors.Extremely uneven quality from various Point of Interest (POI) data suppliers.Apple could easily and greatly improve their map product by switching to outstanding Zenrin data, but they have not taken the opportunity. Poor quality map data from supplier Increment P (now called GeoTechnology), especially weak in rural areas.Before diving in it is important to be acquainted with the basic longstanding quality problems that Apple Maps Japan has suffered from: Justin O’Beirne Apple Maps Feature Availability (4/2022) shows Apple Maps as a very western-centric product, far larger Asian cities have far fewer features and the Guides category are only available in English certainly not Japaneseįor this iOS 15 Apple Maps non-review, I’ll limit observations to a few features in Japan, or lack thereof. His useful availability table illustrates the dilemma, as you can see Maps feature availability is all over the place. Nobody has mapped the vast Apple Maps effort better than Justin O’Beirne but even he limits his analysis to cartography comparisons and listing feature availability rollouts. Regions outside of major metropolitan areas only have a small sub-set of those services. Apple uses many different local data suppliers of varying quality to deliver most map services for each country.
The reason for this of course is that much of Apple Maps is outsourced, very little is collected in-house and created by Apple. The vast collection of services under the Maps umbrella is such that a comprehensive overview would require separate reviews of each category and country: (1) Basic Directions: driving, transit, bike, walking, (2) Search: pre-canned Nearby, Point of Interest, etc., (3) Two different versions of Look Around, (4) Guides, (5) Last but not least: cartography design and map data quality. The iOS 15 Apple Maps users get in California is completely different from the Apple Maps users get in Japan. Reviewing Apple Maps is impossible because it’s not the same product everywhere.
