Disease Mapping: GIS Helps in Pandemic Preparation

…from Western Australia Today

“New technologies will allow corporations to gain a much better understanding of how a pandemic would affect the smooth running of their businesses. Interestingly, a technology known as geographic information systems being developed for use by modern corporations to understand where disease clusters are located has its origins in the 19th century.

““Disease mapping developed during the 1830s cholera outbreak in the UK. Post-epidemic, information from doctors about the number of cases that presented at their surgeries was collected, which was used to develop maps with dots representing cholera cases. The maps tracked the spread of the illness over time and clearly showed disease clusters around ports like Liverpool and Manchester, and also accounted for ancillary factors such as how the disease spread through the British canal system,” explains Francisco Urbina, manager of business development strategy at location intelligence company, ESRI Australia, which develops GIS solutions.

“Although GIS technology has come a long way since the mapping techniques used in the 1830s, the principles behind disease mapping remain the same.”

Greenprint Priority for Microsoft Surface: New Demo from ESRI’s Application Prototype Lab

“The following demonstration uses the Surface to display a map of an area and instructs a remote mapping server to perform intensive suitability analysis.  The parameters for the analysis are on the right hand side of the screen and the results are displayed on the left.  This demonstrates how the Surface can be used to perform “what if” environmental analysis.”

Cartogram of Global CO2 Emissions in ArcGIS

…reposted from the ESRI GIS Education Community blog

Cartograms, because they distort our normal view of things, are wonderfully rich research and teaching tools. A distance cartogram shows relative travel times and directions within a network. An area cartogram is a map in which some variable is used instead of the land area in each polygon to compute the size of that polygon. Many of us remember using graph paper to make rectangular area cartograms as undergraduates (but perhaps I am dating myself). Today, one can use Web GIS and desktop GIS to create cartograms. For example, nearly 700 variables can be mapped on www.worldmapper.org, and the data can be downloaded as Excel spreadsheets and analyzed within ArcGIS.

To dig deeper and make your own cartograms, with the ability to do bivariate analysis within a GIS environment, use the ArcScript cartogram tool that Tom Gross in the ESRI Applications Prototype Lab created, on: http://arcscripts.esri.com/details.asp?dbid=15638. How can a GIS, which focuses on the accurate spatial representations of features, be used to create cartograms? Try this script and find out!

Once you install the cartogram tool, inside ArcMap, access ArcToolbox. Create a toolset, add the cartogram tool, and run it. The intuitive interface allows specifying input and output, and even comes with a nice assortment of international population and other variables to practice on. You can distort the base layers so that your cartogram can include the distorted layers for reference. I did this for cities, a 30-degree world grid, and a satellite image of the Earth to see these reference layers overlaid on my cartogram.


In this example, I chose to map the total CO2 emissions by country in 2004, in millions of metric tons, from the US Energy Information Agency. What patterns do you notice?

The cartogram map layer has to be written into a geodatabase, but otherwise, the tool has few restrictions. I am very pleased cartographically with the results, and the methodology of how the cartograms are generated is well documented.

What other variables and scales could you map and analyze as cartograms?

Virginia Space Grant Consortium Project to Build Geospatial Technology Web Portal

The Virginia Space Grant Consortium has been awarded a grant of $894,228 by the National Science Foundation’s Advanced Technological Education program (NSF-ATE) for the Geospatial Technician Education through Virginia’s Community Colleges (GTEVCC) project.  Project partners include the Virginia Community College System (VCCS), John Tyler Community College, Tidewater Community College, Virginia Western Community College, and the Virginia Geospatial Extension Program at Virginia Tech.

The vision of the GTEVCC project is to establish academic pathways in geospatial technology (technologies such as geographic information systems/global positioning systems/remote sensing) at three community colleges in the VCCS that will provide Virginia employers with a larger pool of skilled geospatial technicians. These academic pathways will serve as model programs for other community colleges.

The GTEVCC project will include educational materials development, adaptation, and implementation, and will provide professional development and mentoring for faculty and high school teachers. Each college will develop a certificate program in Geographic Information Systems (GIS) and update their existing GIS courses and programs to better reflect the employer’s needs. The curriculum developed through the GTEVCC project will be driven by the needs of business and industry in the Commonwealth.

The project team will create and maintain a geospatial technology web portal to serve as a repository for pathway models, curriculum, professional development materials, career awareness materials and other resources.  The project team will also develop geospatial technology career awareness resources and materials to be shared statewide.

“We’re delighted with this NSF grant that will allow our colleges to remain at the cutting-edge of an exciting and growing field, “said Dr. Glenn DuBois, Chancellor of Virginia’s Community Colleges.  “It’s yet another example of the partnerships that our colleges build with one another, business and industry, and higher education institutions.  Most importantly, this continuing partnership with the Virginia Space Grant Consortium will lead individuals to jobs, and it will reap increasing rewards and workforce development opportunities for communities and businesses across Virginia,” said Dr. DuBois.

Chris Carter, VSGC Assistant Director, states, “The VSGC is honored to lead the GTEVCC effort on behalf of the VCCS, the partnering community colleges, and the Virginia Geospatial Extension Program.  The VCCS has a strong commitment to geospatial technology education and meeting the needs of employers across the Commonwealth. Virginia is lucky to have such a large and dedicated group of professionals and educators in the geospatial technology field. I am very proud of the collaboration and effort of the GTEVCC team that has already accomplished so much through our planning grant.  I look forward to the next three years working with this team.”

The benefits of this partnership are recognized by business and industry representatives. Russell Minich, Principal with the Timmons Group has been a participant on the project since the planning team first met several years ago.  “The NSF-funded GTEVCC project is GREAT news for the partnering community colleges, the VCCS and the Commonwealth.  I really look forward to serving on the advisory committee and providing the business community prospective. We are the major consumers of the community college product, a trained workforce,” Minich stated.

NSF’s ATE program supports the development of technicians in emerging fields, recognizing the need to inspire, motivate, and empower students to develop and achieve career goals. NSF funds ATE projects that focus on developing partnerships between community colleges, other higher education institutions and employers to provide workforce development and education of science and engineering technicians at the undergraduate and secondary school levels.

University of Texas at Austin will Use GIS to Study Climate Change and Political Stability in Africa

“The Robert S. Strauss Center for International Security and Law has been awarded a $7.6 million grant by the U. S. Department of Defense, the largest single award dedicated to social science research The University of Texas at Austin has received.

“The five-year grant will fund the Strauss Center’s Program on Climate Change and African Political Stability (CCAPS), which will identify how climate change could trigger disasters in Africa that undermine political stability. The program will explore strategies for building African state capacity and assess global aid efforts while developing partnerships with the Africa policy community in the United States, Africa and elsewhere.

“”CCAPS utilizes the most rigorous methods available to social scientists,” said Catherine E. Weaver, Strauss Center distinguished scholar. “It combines extensive qualitative fieldwork in Africa with the sophisticated use of quantitative analysis and Geographic Information System (GIS) software to better understand the complex relationship between climate change risks, political vulnerability and international aid activity.””
