Place and Spatio-temporal Constraints on Social Networks

Spatio-Temporal Constraints on Social Networks Workshop, University of California, Santa Barbara, Center for Spatial Studies, 13-14 December 2010

Brent Hecht

“My interest in spatio-temporal constraints on social networks is twofold. First and foremost, I am focused on what can be learned about places from mining and understanding spatiotemporal constraints on social networks. For instance, how do we define a “local user” in the context of an online knowledge creation-oriented social network? [2] How do we communicate the degree of “localness” to a content consumer? My colleagues and I are also working toward applying this research in novel systems and applications. Second, I am a Ph.D. student in human-computer interaction with a background in geography and close ties to the fields of communication, psychology, and sociology. As a result, I have been involved in many brainstorming sessions in which questions arise about spatio-temporal constraints on social networks. I thus very much appreciate the need for additional research in this area, as well as increased communication between the multitudes of interested disciplines.”

Alabama Moves Its Redistricting Process to the Web

Solution Combines Geospatial Analysis with Online Collaboration

This year, the state of Alabama is redrawing its district lines using a flexible geographic information system (GIS)-based online platform. The Alabama Legislative Reapportionment Office procured a web-based redistricting solution from Esri that incorporates the collaborative capabilities of the Web with sophisticated geospatial analysis tools required for redistricting.

While the sharing of proposed district plans on the open web is gaining momentum, Alabama is one of the first states to bring its entire redistricting process online. Alabama opted for the web-based solution because it supports secure development of redistricting plans from numerous locations without the need to purchase, install, and maintain desktop software. Legislators can create plans, share them with specific groups, and evaluate each plan’s viability and integrity before submitting to the Reapportionment Office for final review. The state also chose the online platform because it facilitates collaboration and data sharing with county governments as required by Section 5 of the Voting Rights Act, which prohibits discriminatory redistricting practices.

Esri’s web-based solutions make it easy to bring transparency to the redistricting process by enabling online sharing of district scenarios and the demographic data behind them. Because Esri redistricting solutions can incorporate basemaps, past census data, existing legislative districts, and projected demographic data, customers can begin to evaluate redistricting scenarios before official 2010 U.S. Census data is released in March. Customers can also incorporate their proprietary information into the application to create a data-rich resource that supports redistricting as well as future legislative and operational decision making.

Web & Wireless GIS 2011

03 – 04 March 2011

Kyoto, Japan

The continuing advances in the development of Wireless and Internet technologies generate ever increasing interest in the diffusion, usage, and processing of geo-referenced data of all types – geomedia. Spatially aware wireless and Internet devices also offer new ways of accessing and analyzing geo-spatial information in both real-world and virtual spaces. Consequently, new challenges and opportunities have been provided that expands the traditional GIS research scope into the realm of Intelligent Media – including geomedia with context-aware behaviours for self-adaptive use and delivery. Our common aim is research-based innovation that increases the ease of creating, delivering and using geomedia across different platforms and application domains that continue to have dramatic effect on society.

Abstracts Sought for GIS-Pro 2011

URISA is now accepting abstract submissions for GIS-Pro 2011: URISA’s 49th Annual Conference for GIS Professionals.  The conference will take place November 1-4, 2011 in Indianapolis, Indiana.

Proposals for presentations, panel discussions, luncheon talks and Ignite presentations are invited. and should fit within one of the program tracks noted below and described in much greater detail online at www.gis-pro.org or www.urisa.org. Abstract submissions are due on or before March 14, 2011.

Roadmaps for GIS Professionals – This track was formed to address a number of issues pertinent to the image and professional development path of the geospatial technologies professional in today’s working world. Professional development plays a large part in defining a profession and also encourages positive growth in your career track. Submit an abstract within this track to share your experiences and ideas about advancing as a GIS Professional.

The Business Benefits of GIS – How do you best illustrate the direct and indirect benefits of GIS utilization and educate your organization about how GIS can increase productivity and save money? Benchmarking, organizational education, GIS maturity models, business case models, ROI techniques, financial and budgeting considerations and success stories where GIS was the answer are some of the topics that are welcomed within this track.

Immersive GIS – What’s next and how do we catch up with what’s already here?  This track welcomes presentations that demonstrate new geospatial industry trends as well as how GIS is being developed to utilize new state of the art technologies.

GIS Speaks Out – This track looks at how GIS technologies, programs, and solutions are maturing across the Enterprise, and, as a result, providing much greater return on investment than if kept in isolated silos. Leadership, governance, creativity, change management, and collaboration, are but a few of the non-technical characteristics that lead to GIS maturity. Share your expertise in how to integrate GIS within other organizational units as well as how to use GIS leadership skills to achieve a pervasive level of maturity within your organization!

One Government – How should public sector representatives of multiple jurisdictions and overlapping levels of government (federal, state/provincial, regional, local) act collaboratively as One Government? What are some tried and true approaches to data sharing challenges and what is the role of government in setting standards?  Can we get government to support and fund spatial data as an infrastructure asset with appreciating value (as opposed to depreciating value) over time?  How can initiatives such as Open Data and Gov 2.0 contribute to a better return on the geospatial investment, while still maintaining necessary protection of privacy?  With any luck, this track will bring together a collective conscience that will provide some insight and creativity into building solutions that address many of these complex challenges!

Abstracts are due on or before March 14, 2011. For further details, visit www.gis-pro.org or www.urisa.org

A GIS-based Spatial Management and Analysis System for Rural Socioeconomic Statistic Data

2010 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 25-30 July 2010, pp. 1691 – 1694

“With the rapid development of database technique and computer technology nowadays, it is no longer a difficult problem to manage mass statistical data with computer and database system. However, from the statistical mode and time series of rural socio-economic statistical survey, we know that the statistical data have both spatial and temporal attribute, so the traditional systems have no enough ability to manage and analyze the statistical data with spatio-temporal attribute. In this paper, on the basis of the former research and the real demands of rural socio-economic statistic department, four key techniques about the construction of spatial management and analysis system for rural socioeconomic statistic data were designed. Based on the statistical spatio-temporal database, historical statistical data spatio-temporal division, statistical model library, exploratory spatial statistical analysis method techniques, the integrative operational system was realized for spatio-temporal data management, analysis and thematic mapping or expression. It could be utilized in many aspects of operational work of rural socio-economic statistic administration.”
