within Esri ArcGIS and creates an interface to conduct population-weighted cluster sampling, selects sample sites, divides the selected sites among survey teams and generates directions for navigating to survey sites. Installation files for the toolbar and documenta- tion describing installation and use can be found at SHARP’s Web site (cphp.sph.unc.edu/sharpgis). The cluster-sampling surveys, containing anywhere lDigital survey forms are programmed to automatically capture the date and time as well as place-specific information such as the census block population and number of households. from 15 to 50 questions, are prepared in ArcPad Studio. Each MobileMapper 6 unit, running Windows Mobile OS and ArcPad, is loaded with the custom survey form and a street-map layer with point des- ignations. Each team uses the MobileMapper 6 to navigate to its assigned points that have been reverse geocoded, associating an address with each survey location. When the team arrives at the specified point, a scripted survey form pops up with dropdown menus as well as check and text boxes to enable the teams to enter and record survey answers. SHARP and UNC CPHP helped state and federal public-health officials leverage GIS and GPS technol- ogy in numerous projects, most notably in rapid needs assessments following hurricanes Isabel (2003), Charley (2004), Rita (2005), Wilma (2005) and Katrina (2005) as well as in preparing for Hurricane Earl (2010). Recently, cluster-sampling techniques have been applied to more novel applications to assess community health, knowledge and beliefs regarding emergency preparedness and the intent to receive the H1N1 vaccine. Women Affected by Georgia Floods During three days in late October 2009, the UNC CPHP conducted a reproductive health assessment in two Georgia counties affected by recent flooding. The assessment’s goal was to interview women between the ages of 18 and 44 in the community to determine whether the flooding led to problems such as trouble accessing prenatal care or contraceptives, increases in stress, or loss of health insurance. Staff from UNC CPHP, the Centers for Disease lA sampling frame in the 10-mile emergency-planning zone of the Shearon Harris Nuclear Power Plant was used for a Potassium Iodide (KI) distribution study to estimate how many households received KI and gauge knowledge and beliefs. When taken at the right time following a nuclear power-plant emergency, KI will protect the thyroid gland and reduce the risk of thyroid cancer. 20 G E O W O R L D / A P R I L 2 O 1 1 Control and Prevention (CDC) and the Cobb-Douglas Georgia Health District were joined by students from two universities—20 students from UNC’s Team Epi- Aid and 12 members of Emory University’s Student Outbreak Response Team. In three days, the teams completed 73 interviews using MobileMapper 6 units loaded with ArcPad. Fourteen of the women interviewed were currently pregnant or less than six months postpartum, a target group for the assessment. Women surveyed reported flood-related income losses, displacement from their homes due to flooding and high levels of related stress. Information from this pilot assess- ment is being used to inform development of a CDC Mobility/GPS Special Issue Health Mapping
