Geographic information system (GIS) mapping can help communities visualize the health of their neighborhoods and identify opportunities for improvement. In Austin, Texas, Children's Optimal Health, a nonprofit association, used GIS to map the prevalence of obesity among middle school children and to identify contributory factors. The maps indicated that obesity is a problem in all Austin middle schools. Two neighborhoods outside downtown Austin have particularly high concentrations of overweight and obese students. Maps also showed that the neighborhoods have different proportions of fast-food outlets, grocery stores selling fresh produce, green recreation space, and students failing cardiovascular testing. The mapping exercise spurred community groups to propose obesity interventions tailored to each neighborhood.
地理信息系统 (GIS) 制图可以帮助社区了解其邻里的健康状况，并确定改善的机会。在德克萨斯州奥斯汀市，非营利组织“儿童最佳健康”（Children's Optimal Health）使用 GIS 绘制了中学生肥胖症的流行情况，并确定了促成因素。地图表明，肥胖是奥斯汀所有中学的一个问题。奥斯汀市中心外的两个社区，超重和肥胖学生的比例特别高。地图还显示，这些社区的快餐店、出售新鲜农产品的杂货店、绿色娱乐空间以及心血管测试不及格的学生的比例也不同。这项制图工作促使社区团体提出针对每个社区的肥胖干预措施。
