Sep 26, 2018

In 2014, Google published a neighborhood map of Brooklyn, the most populous borough in New York City, a seemingly harmless step in providing its users with useful geographic boundary information. The backlash was swift. Residents of Brooklyn responded angrily, many stating that a commercial company such as Google had no right to label and define boundaries within their city. This was not a lone incident, as many mapping agencies, both government and commercial, have come to realize that...

GIScience Conference 2018

Sep 6, 2018

The Tenth International Conference on Geographic Information Science (GIScience ‘18) came to a close last week in Melbourne, Australia. By all accounts the conference was a success and it was great to catch up with colleagues and researchers I maybe only get to see once a year. The Location Privacy and Security Workshop (LoPaS '18) held on the first day of the conference went well with an excellent keynote, three thought...

New paper exploring the similarities between tourist attractions

Aug 6, 2018

The motivation for tourists to visit a city is often driven by the uniqueness of the attractions accessible within the region. The draw to these locations varies by visitor as some travellers are interested in a single specific attraction while others prefer thematic travel. Tourists today have access to detailed experiences of other visitors to these locations in the form of user-contributed text reviews, opinions, photographs, and videos, all contributed through online tourism platforms....

Two short papers to be presented at GIScience 2018 in Melbourne, Australia

Dynamic Place Type Regions - Visual Analytics Platform

Nov 1, 2017

Place-based social sharing applications offer new opportunities to better understand the dynamics of human activity behavior. These application provide access to billions of user location check-ins that promote a better understand of the popularity of places and regions within a city. In this work, we present a visual analytics platform for exploring the dynamics of place-driven urban activity behavior. This platform allows users to exploit the spatiotemporal resolution of place...
