The 6th GIS-focused algorithm competition, GISCUP 2017, co-located with ACM
SIGSPATIAL GIS 2017, November 7 - November 10, 2017, Los Angeles, CA, USA

http://sigspatial2017.sigspatial.org/giscup2017/

This year will be the 6th GIS-focused algorithm competition, GISCUP 2017,
co-located with the 2017 ACM SIGSPATIAL GIS conference. ACM SIGSPATIAL hosts an
annual algorithm contest with the goal of encouraging innovation in a fun way.
The winners will be announced at the ACM SIGSPATIAL GIS conference in November
2017. Contest participants will submit original computer programs to be
evaluated by the contest organizers on common datasets.

This year’s contest will focus on the growing research area of trajectory
computing. Massive amounts of spatial trajectories are generated nowadays by
smartphones, infrastructure, computer games, natural phenomena, and many other
sources. A trajectory consists of a time series of locations with the assumption
that some sort of interpolation (often piecewise linear) is reasonable. In this
way, trajectories are one-dimensional geometric objects, but their
representation in computer systems is usually zero-dimensional as a series of
pairs of location and time, for example.

Trajectory similarity is a very basic problem when dealing with this type of
data and many different ways of comparing trajectories have been proposed. In
this challenge, we concentrate on a very intuitive measure called Fréchet
distance with hard computational complexity, but superior quality in theory and
practice.

The Fréchet distance is defined as the minimal length of a leash connecting a
dog on one trajectory with its owner on a second trajectory, both never moving
backwards. For this challenge, the "true" Fréchet distance shall be used, though
teams are free to exploit the existing approximations including the Discrete
Fréchet distance as they wish. The challenge for this year consists of finding
and combining spatiotemporal indexing schemes with efficient algorithms for
Range Queries in very large databases of trajectories. The approaches will be
evaluated on a multitude of real and synthetic datasets, a sample datasets can
be found on the download page page.

In summary, the key topics that are being addressed in this year’s cup are the
following:
- Spatio-temporal Big Data
- Trajectory Computing
- Computational Geometry
- Indexing and Retrieval in Spatial Computing

The top three teams will be provided with cash and / or other prizes. In
addition to these prizes, the top three teams will be invited to submit a four
page paper for a contest paper session to be held at the 2017 ACM SIGSPATIAL GIS
conference. These papers will be subject to review and acceptance by the contest
organizers, but it is expected that each of the top three teams will have their
paper in the conference proceedings and a ten-minute presentation in the contest
session.

At least one team member of each winning team must register for the 2017 ACM
SIGSPATIAL GIS conference.
