Kartta: Extracting Landmarks near Personalized Points-of-Interest from User Generated Content


Most mobile navigation systems focus on answering the question, “I know where I want to go, now can you show me exactly how to get there?” While this approach works well for many tasks, it is not as useful for unconstrained situations in which user goals and spatial landscapes are more fluid, such as festivals or conferences. In this paper we describe the design and iteration of the Kartta system, which we developed to answer a slightly different question:
“What are the most interesting areas here and how do I find them?”
