Both the iOS Maps app and the OS X program offer a built-in way to report any inaccurate data.
Why might you want to do this, you ask? Well, I’ve had several instances in which I reported issues to Apple (such as a business address being listed in the wrong location), and their response has been awesome. In some cases, I’ve seen information be corrected within a couple of days! So it’s a way that you can help Apple make Maps better in your town, and fortunately, it’s pretty easy to do. Within iOS, you’ll tap the small “i” in the lower-right corner to get started.
Touch “Report a Problem,” and you’re off to the races.
Within OS X, you’ll click on the “Maps” menu in the upper-left to select “Report a Problem.”
And in both cases, Maps will walk you through the reporting process afterward, which is relatively painless.
As I noted, Apple seems quite responsive to these reports, so if you’ve found problems with Maps, it’s a great idea to attempt to get things corrected. It kind of makes me feel as if I’m doing my civic duty, but I’m weird like that.
