SIGSPATIAL Cup 2016

News Date: 
23 Mar 2016
Details: 

The 5th GIS-focused algorithm competition, GISCUP 2016, co-located with ACM SIGSPATIAL GIS 2016, October 31-November 3, 2016, San Francisco, CA, USA

Call for Submissions

This year will be the 5th GIS-focused algorithm competition, GISCUP 2016, co-located with the 2016 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 2016. Contest participants will submit original computer programs to be evaluated by the contest organizers on a common dataset.

This year’s contest will focus on applying spatial statistics to spatio-temporal big data in order to identify statistically significant hot spots using a distributed computing framework and functional programming languages. With the advent of the ubiquitous collection of spatio-temporal observational data (e.g., vehicle tracking data), the identification of
unusual patterns of data in a statistically significant manner has become a key problem that numerous businesses and organizations are attempting to solve. This year’s SIGPSPATIAL Cup addresses this significant programming challenge.

For this year’s contest, each team will utilize a very large collection of spatio-temporal observational data – the New York City Taxi and Limousine Commission Yellow Cab trip data. This dataset consists of over one billion records representing all Yellow Cab taxi trips in New York City between January 2009 and June 2015. Each record in the dataset contains key
information such as pickup and dropoff date, time, and location (latitude, longitude), trip distance, passenger count, and fare amount.

Given this dataset, each team will then identify the fifty most statistically significant dropoff locations by passenger count in both time and space using the Getis-Ord statistic. Space will be aggregated into a 200m grid; time will be aggregated into two hour periods. Each team will utilize the Apache Spark open source cluster computing framework; the tests will be run on a cluster of twenty five commodity-level PCs (3GHz, quad core), each equipped with 24 GB of RAM and 3 TB of disk storage. The applications that will run on top of the Spark framework can be implemented using Java, Python, or Scala using functional programming techniques. The dataset will be provided in HDFS as a collection of uncompressed CSV files.

In summary, the key topics that are being addressed in this year’s cup are the following:

  • Spatio-temporal data
  • Big data
  • Spatial statistics – Hotspot analysis
  • Distributed processing
  • Functional programming

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 2016 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, a ten-minute presentation in the contest session, and a poster presentation in the conference’s regular poster session.

At least one team member of each winning team must register for the 2016 ACM SIGSPATIAL GIS conference.

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

Editorial - March 2016

Dear members of the Network/ readers of the Newsletter,

As you may find out, this issue has almost twice as much material from the previous issues, thanks to the great job of all the co-editors and the members of our network. You can find very interesting articles, based on discussions done in February, about AgriGIS, Global School Network, the Open City Smart project, and NASA World Wind.

From these four, the newest one is the beginning of the discussion about the formation of a Global School Network. As the discussion has just started, I would like to share with you why I think there is a need of a Global Network. First of all, this would put an order to the situation we face of many people doing things with no coordination; no “Central Instructions;” no “basic ideas” of what, when and how to do it. Most of us work at a university or a research centre, and whatever we do is for the students of higher education.

In my opinion, we have to focus on the base of the educational system. It is very easy to teach university students. They know a lot of things, and it is easy to teach them, using complicated words and concepts, about spatial science. But what about the students in primary and secondary education? How can we make them understand how spatial the world in which they live is, and how can they use the tools we have constructed in order to manipulate the spatiality of our world?

We can't do this if we don't get all the help we can from their teachers. But even the teachers have different ideas about the way they can teach about this world. In fact, everything has to do with the pedagogical part of the spatial tools we use and the curriculum of each level in each country. This is why we have to work with the teachers, as they work with their students, so they can let us know what their needs are. In some cases we do have some information from published articles, but it has to be more organized and, why not, more guided.

Finally, there was an interesting telemeeting with Christopher Tucker, Chairman of the Board of Trustees, The MapStory Foundation, in which Chris let us know more about MapStory and what it can do for the teachers and students. We all hope that Chris will share with us an article on MapStory, and we will have the pleasure to publish it in a future issue.

Have a nice reading.

Dr.Nikos Lambrinos, Chief Editor.
