When it comes to map mashups there's no doubt that Google Maps leads the way. On ProgrammableWeb we list 1,964 Google Maps mashups, almost four times as many as any other API. This popularity makes utilities built on top of Google Maps especially interesting, such as this contextual menu control, which pops up a menu when the user right clicks.
Location data platform Factual has today released two new services - previously described by industry leaders as personalization APIs – that will enable developers to create a more intimate, contextual level of engagement with their mobile app users.
