Applied Geospatial Techniques
Geographical Information Systems (GIS) links location based information (spatial) to database information (tabular) enabling the user to visualize patterns, relationships and trends. This means of analysis grants a new perspective to information, which is practically absent from exclusively tabular data. Using GIS, we can manage, analyze, query and interact with geographically referenced information using Spatial Analysis techniques. Spatial Analysis itself is the study of the distribution and clustering of events and/or objects in space, in conjunction with their attribute characteristics. At present, the department of Geography is the only department at the George Washington University with the requisite skill and training programs to offer these types of analyses.
During the past several years, the Department of Geography has become an important vehicle for student geospatial training and support through tailored short-term projects undertaken in cooperation with university departments and offices, local non-profit organizations, bilateral and multilateral agencies, government organizations, and private institutions. Furthermore, the wide reaching application of geospatial technology gives students and teachers the opportunity to fulfill the University's commitment to interdisciplinary collaboration and community service. Many projects established by the department have evolved into substantial long-term research and development activities in the Greater Washington area.
Some of the collaborative geospatial projects conducted by the department include:
- Children's National Medical Center (Children’s Hospital DC): We have participated in several research projects with the Medical Faculty at Children's National Medical Center. The first collaboration looked at pediatric vaccination coverage in Washington DC, and how this is potentially related to Primary care provider accessibility for the study population. The second collaboration examined the spatial distribution of burn trauma in the city, with the express purpose of community education and advocacy. The third collaboration looked at the nature and spatial distribution of unnecessary ER visits to Children’s. The most recent collaboration looks at childhood obesity in the Washington DC Metropolitan area, and at how the introduction of geospatial analysis tools can help us understand the spatial distribution of this condition, informing both the research community, patient advocacy groups, and the public themselves.
- National Institutes of Health: This funded research project is entitled “Health, Poverty and Place: Modeling Inequalities in Accra Using Remote Sensing and GIS.” The GWU Geography Project Team, Dr. Engstrom and Dr. Rain work in collaboration with colleagues from the Harvard University School of Public Health and the San Diego State University.
- The World Bank: GWU Geography begun it’s successful collaboration with the World Bank in 2006, with a transportation infrastructure GIS project for Nepal. We have continued to collaborate with the Bank, and have developed and delivered several tailored GIS workshop to Bank staff using World Bank GIS data and field office scenarios.
- Academy for Educational Development (AED): GWU Geography worked with AED to build a spatial data inventory for Equatorial Guinea relating to a census of schools currently being conducted there. Map products produced by GWU Geography were presented to the Minister for Education in Equatorial Guinea.
- Pan American Development Institute: GWU Geography geocoded and developed a series of maps charting civil society organizations and activities, for the Cuba Development Initiative.
- GWU Office of Real Estate in conjunction with Casey Trees: As part of a service learning initiative, Dr. Lisa Benton-Short's, Building Cities class (GEOG 187), worked with the GWU Office of Real Estate and DC environmental non-profit Casey Trees to create a tree/vegetation inventory of the campus. These data were used in class projects to suggest “green” additions to the proposed campus plan. All data from the project were presented to both organizations.
- GWU Office of Government, International & Community Relations: In celebration of President Knapp's Inauguration in November 2007, the Office of Government, International & Community Relations commissioned a series of maps to illustrate community based partnerships among GWU Schools, and district organizations. Due to the success of this series of maps, Geography was asked to extend this project to map GW governmental, and eventually GW business partnerships in the District.
- GWU School of Business: This project examined the spatial proximity of critical infrastructure to major rail lines, and is currently determining a methodology to determine a Criticality Index for particular lines, based on economic, business, and census data.
- GWU SIGUR Center, PISA: In 2009 a proposal entitled “Proposal for a Leadership Institute on Creative Responses to Global Climate Change” was funded by the Ford Foundation. The project was designed to help the country of Vietnam to improve their response to the potential impacts of climate change. The department of Geography provided geospatial training to a team of Vietnamese government delegates, visiting Washington DC. This work was collaboration between the Elliott School's SIGUR Center Program for International Studies in Asia, and the Geography Department.
