WK01. 2012 International Workshop on Modern Accelerator Technologies for GIScience (MAT4GIScience 2012)

Format: half-day Workshop
Link: http://www.prism.gatech.edu/~ag124/mat4giscience.htm
Organizers: Xuan Shi and Volodymyr Kindratenko
Contact: Xuan Shi (Xuan.Shi@coa.gatech.edu)
Proceedings: MAT4GISCIENCE_ALL_PAPERS.pdf

GIScience community has been an active user of high-performance computing (HPC) resources for data-intensive and compute-intensive applications. The HPC technology, however, is shifting from homogeneous systems employing identical processing elements to hybrid computing architectures that employ multi-core processors in combination with special-purpose chips. New multi-core architectures combined with application accelerators hold the promise of increasing performance by exploiting levels of parallelism not supported by the conventional systems. Examples of such architectures include Cell-based RoadRunner, hybrid system of combined CPUs and GPUs like Keeneland, and FPGA-based Novo-G systems. While there is general trend towards hybrid systems, current GIScience applications require significant algorithmic re-design and software re-engineering efforts to take advantage of the diverse computing resources. This workshop will provide a collaborative forum for GIScientists, geographers, geoscientists, and computer scientists to discuss and share the state-of-the-art accelerator technologies and the pioneering applications, and promote collaboration on deploying the modern accelerator technologies in GIScience.

WK02. GeoVisual Analytics, Time to Focus on Time

Format: full day workshop
Link: http://geoanalytics.net/GeoVA(t)2012
Organizers: Gennady and Natalia Andrienko (Fraunhofer Institute IAIS), Jason Dykes (City University), Menno-Jan Kraak (ITC), Heidrun Schumann (University of Rostock)
Contact: Gennady Andrienko (gennady.andrienko@iais.fraunhofer.de)

The theme for the workshop and the special issue of the Information Visualization journal is the use of GeoVisual Analytics approaches for exploring and analysing large data sets with both spatial and temporal components. We encourage innovative papers detailing tight integration of visualization, data mining, database processing, optimization and other computational processing.

WK03. Time-Geographic Information Science: a workshop on Time-Geography

Format: full day workshop
Link: http://www.geografie.ugent.be/cartogis/research/time-geographic-is
Organizers: Otto Huisman and Tijs Neutens
Contact: Otto Huisman (huisman@itc.nl)

This full-day workshop aims to bring together researchers applying Time-Geographic concepts and methodologies in their research, in the multidisciplinary context of GIScience. Recent years have spawned a large number of academic contributions from around the world that have significantly advanced Time-Geography in conceptual, analytical and empirical ways. We aim to establish an overview of the 'state of the art' in this research field, and hope to identify and formulate the main research challenges. The workshop will include around 5-6 full papers, around 7-8 short papers, and a panel discussion "developing a co-ordinated research agenda." To encourage young scientists and PhD students to participate, several slots will be provided. Specific topics and details will follow in the call for papers.

WK04. Workshop on GIScience in the Big Data Age 2012

Format: full day workshop
Link: http://stko.geog.ucsb.edu/gibda2012/
Organizers: Krzysztof Janowicz, Carsten Kessler, Tomi Kauppinen, Dave Kolas, Simon Scheider
Contact: Krzysztof Janowicz (jano@geog.ucsb.edu)
Proceedings: GIBDA-Proceedings.pdf

The rapidly increasing information universe with new data created at a speed surpassing our capacities to store it, calls for improved methods to retrieve, filter, integrate, and share geo-data. The vision of a data-intensive science hopes that the open availability of data with a higher spatial, temporal, and thematic resolution will enable us to better address complex scientific and social questions. However, on the downside, understanding, sharing, and reusing these data becomes more challenging. Big Geo-Data is not only big because it involves a huge amount of data, but also because of the high-dimensionality and inter-linkage of these data sets. This makes on-the-fly integration of heterogeneous data from various sources a core research challenge for GIScience.  We hope that the workshop will help better define the data, knowledge representations, infrastructure, reasoning methodologies, and tools needed to link and query massive geo-data based on their spatial and temporal characteristics.

WK05. Geographic object based multi-scale analysis

Format: full day workshop
Link: http://dk-giscience.zgis.net/
Organizer: Thomas Blaschke
Contact: Thomas Blaschke (Thomas.Blaschke@sbg.ac.at)

The purpose of the workshop is to define and discuss a methodology for bridging remote sensing centred GEOBIA approach and GIScience concepts to delineate, manage and manipulate objects. In GIScience attempts were made to provide the theoretical foundations for objects such as the concept of fields. In remote sensing the concept of Geographic Object Based Image Analysis has strongly gained in popularity. A preliminary literature analysis shows that the terms "OBIA" and "GEOBIA" attract more citations in scientific literature than the terms "GIScience" and "Geographic Information Science." The workshop will critically discuss the way how to strengthen the theoretical and methodological foundation. It will bring together leading experts from both fields and aims to demonstrate the potential of extending GEOBIA concepts beyond images. Short position statements or short technical notes are invited that highlight the integration of GIScience and OBIA concepts on topics such as:

* objectification: non-technical issues of segmentation steps and alternative solutions
* methodological issues of object handling
* transferability and interoperability of rule sets
* multi-scale theories and concepts
* ontologies and semantics of objects
* GeoIntelligence -- location aware objectification

WK06. Role of Volunteer Geographic Information in Advancing Science: Quality and Credibility

Format: full day workshop
Link: http://www.ornl.gov/sci/gist/workshops/2012/index.shtml
Organizers: Budhendra Bhaduri, Rodolphe Devillers, Muki Haklay, and Michael Goodchild

Recent advancements in geospatial and cyber technologies, combined with a population that is well informed and interested in global issues, have cultivated an environment in which scientific research can potentially benefit significantly from the enormous volume of data that can be provided by citizens through their offering of volunteered geographic information (VGI). Social networks also provide a vast volume of VGI that can include observations (e.g. vegetation, critical infrastructures), measurements (e.g. temperature), and even personal perspectives and experiences in the form of images, videos, and text. However, the value of VGI is still largely limited to satisfying the intellectual curiosity of the common public. The critical challenge that faces the research and operational communities is to assess the quality of VGI by understanding and assessing its authenticity, validity, and uncertainty. Determining the most appropriate sources of data, promoting the involvement of those sources, acquiring accurate and useful information, assessing and communicating the accuracy of the data, and ultimately connecting these data with scientific research are key issues that need to be addressed in this context.


T01. Decentralized spatial computing with NetLogo agent-based simulation

Format: half-day tutorial
Link: http://ambientspatial.net/giscience
Organizer: Matt Duckham
Contact: Matt Duckham (matt@duckham.org)

This tutorial will cover how to design, build, simulate, and test decentralized spatial and spatiotemporal algorithms. Decentralized algorithms can operate in distributed spatial information systems that have no centralized controller or information repository (like groups of smartphones, vehicle ad-hoc networks, and geosensor networks). The tutorial will use examples of algorithms drawn from a wide range spatial and spatiotemporal problems, from querying topological relations between regions monitored by a geosensor network, to identification of meaningful movement patterns in groups of individuals equipped with location-aware mobile devices. In addition to covering fundamental decentralized spatial computing concepts, the tutorial is designed to be a practical introduction to agent-based simulation of decentralized spatial algorithms. The simulation system used will be NetLogo, a powerful and intuitive agent-based simulation system that has a wide range of applications in geographic information science, and a growing user community.
