Thanks to Apple continuing to rely on Google Maps for location data on iCloud.com, Apple’s Find My iPhone service on the web currently takes advantage of Google’s indoor mapping data for certain malls and retailers. For example, the screenshot shown above includes a detailed floor layout of my local Best Buy, a feature found on Google Maps but not Apple Maps. This would be particularly useful if you lost an iOS device at a location with indoor mapping support from Google.
Apple previously relied on Google Maps for its Find My iPhone apps on iOS until it rolled out its own mapping service. While the indoor mapping feature is currently present on iCloud.com, it would disappear if Apple ever replaced the mapping data with its own as it currently stands.
For its part, Apple has acquihired an indoor mapping company’s talent, specifically from BroadMaps, in 2013.
