GIS Day @ UCSB Geography

GIS day is the third Wednesday of November in each year, during the Geography Awareness Week. As a global event, GIS day provides a great opportunity for GIS users and researchers to exchange ideas and present works to a wide audience. To celebrate this special day for spatial studies, we will hold a lightning talk on Nov. 18th (Tuesday) at the UCSB Center for Spatial Studies. We sincerely invite you to join us and present your work.

POI Pulse paper accepted for publication

Just a quick update to mention that our paper POI Pulse: A multi-granual, semantic signatures-based information observatory for the interactive visualization of big geosocial data by Grant McKenzie, Krzysztof Janowicz, Song Gao, Jiue-An Yang and Yingjie Hu was accepted for publication through Cartographica: The International Journal for Geographic Information and Geovisualization.

POI Pulse: A Multi-Granular, Semantic Signatures-Based Approach for the Interactive Visualization of Big Geosocial Data

The text below is from a recent paper on which we've been working:

New Lab Space, Interactive Display, and Google Glass

The STKO lab is moving up in the world (or down to be geometrically accurate). The new lab space opened at the beginning of this year on the 4th Floor in Ellison Hall (one floor down from our previous offices). The bullpen style of the new lab is something we have wanted for a while and really enhances the collaborative environment we encourage in the group.

Weighted Multi-Attribute Matching of User-Generated Points of Interest

A significant amount of the work that we’ve been doing lately has made use of the plethora of user-generated, geospatially-related content publically available online. Web applications such as Yelp, Google Places and Foursquare provide access to tens of millions of points of interest (POI) worldwide. These POI offer a range of descriptive information ranging from semi-structured content such as price range ($$) and ambiance, to unstructured review text and personal user check-ins.
