The contest will focus on geo-fencing - a virtual perimeter for a real-world geographic area, widely used in location-based services, such as advertisements and child location services.


The contest will be about geo-fencing, which represents a virtual perimeter for a real-world geographic area. Geo-fencing is used widely in location-based services, e.g., location-based advertisements (which send the targeted ads to the users when they are close to the shopping mall) and child location services (which notify parents when a child leaves a designated area).

For the contest, each team will be given access to a large amount of point locations and spatial polygons along with some spatial predicates. We want to find every (point, polygon) pair in the dataset that satisfies the spatial predicate. The submitted programs will be evaluated by the contest organizers on multiple datasets and will be ranked quantitatively based on their correctness and speed.

In addition to the prizes, the top three teams will be invited to submit a four page paper for a contest paper session to be held at the 2013 ACM SIGSPATIAL GIS conference, Nov 5-8, 2013, Orlando, FL, USA.

Submissions are due August 1st, 2013 at 17:00 PST.
