Keynote Speakers Announced for Global Geospatial Conference 2012 in Quebec

The joint organizers of Global Geospatial Conference 2012 are delighted to announce Dr. Gilberto Câmara (Brazil), Dr. Prashant Shukle (Canada), Dr. Michael Goodchild (US) and Dr. Abbas Rajabifard (Australia) as featured keynote speakers at the upcoming May conference.

Dr. Gilberto Câmara is General Director of Brazil’s National Institute for Space Research (INPE) and will address the topic of Global Visions in Sharing Geospatial Data and Tools and Progress in Their Achievement. Dr. Camara is being honored as well with a Global Citizen Award for his staunch support and highly influential global leadership in opening citizen access to governments’ environmental and geospatial data across the planet.

Dr. Prashant Shukle, Director General of the Mapping Information Branch of Natural Resources Canada, will highlight substantial innovations employed and advancements made in spatially enabling Canadian government services and providing access for businesses and citizens.

Dr. Michael Goodchild, member of the U.S. National Academy of Sciences and Director of the University of California-Santa Barbara’s Center for Spatial Studies, will provide a personal perspective on topics raised at the conference and topics drawn from his over forty years in supporting and observing advancements in the field.

Dr. Abbas Rajabifard, Chair of the Department of Infrastructure Engineering at The University of Melbourne and President of the GSDI Association, will open the conference with an address on Visions for Spatially Enabling Government, Industry and Citizens.

GGC 2012 will take place at the Québec City Convention Center from May 14-17, 2012. This conference combines the GSDI World Conference (GSDI 13), 14th GEOIDE Annual Scientific Conference, Canadian Geomatics Conference (CGC 2012) and the 7th 3D GeoInfo Conference. In addition to the keynotes, the conference has a full slate of corporate sponsors, the exhibit space is sold out, a full program of technical and plenary sessions will be presented, additional poster and industry showcase sessions will be highlighted and the social events have all been booked.

We congratulate titanium sponsor Tecterra, platinum sponsor Esri/Esri Canada and all of the other sponsors, exhibitors, and speakers that promise to make the conference a great success.

Come join your professional, government, industry and academic peers in beautiful Quebec City in May 2012!

Objective Assessment of Obesogenic Environments in Youth: Geographic Information System Methods and Spatial Findings from the Neighborhood Impact on Kids Study

American Journal of Preventive MedicineAmerican Journal of Preventive Medicine, May 2012, Vol. 42, No. 5

“Background: GIS-based walkability measures designed to explain active travel fail to capture “playability” and proximity to healthy food. These constructs should be considered when measuring potential child obesogenic environments.

“Purpose: The aim of this study was to describe the development of GIS-based multicomponent physical activity and nutrition environment indicators of child obesogenic environments in the San Diego and Seattle regions.

“Methods: Block group–level walkability (street connectivity, residential density, land-use mix, and retail floor area ratio) measures were constructed in each region. Multiple sources were used to enumerate parks (~900–1600 per region) and food establishments (~10,000 per region). Physical activity environments were evaluated on the basis of walkability and presence and quality of parks. Nutrition environments were evaluated based on presence and density of fast-food restaurants and distance to supermarkets. Four neighborhood types were defıned using high/low cut points for physical activity and nutrition environments defıned through an iterative process dependent on regional counts of fast-food outlets and overall distance to parks and grocery stores from census block groups where youth live.

“Results: To identify suffıcient numbers of children aged 6–11 years, high physical activity environment block groups had at least one high-quality park within 0.25 miles and were above median walkability, whereas low physical activity environment groups had no parks and were below median walkability. High nutrition environment block groups had a supermarket within 0.5 miles, and fewer than 16 (Seattle) and 31 (San Diego) fast-food restaurants within 0.5 miles.Lownutrition environments had either no supermarket, or a supermarket and more than 16 (Seattle) and 31 (San Diego) fast-food restaurants within 0.5 miles. Income, educational attainment, and ethnicity varied across physical activity and nutrition environments.

“Conclusions: These approaches to defıning neighborhood environments can be used to study physical activity, nutrition, and obesity outcomes. Findings presented in a companion paper validate these GIS methods for measuring obesogenic environments.”
