How improving GIS technology improves lives

Geographic Information Systems (GIS) is not a new technology at DOH, but how we plan to use it is changing. Since 1999, DOH has created colorful maps that plot disease surveillance data by location. By looking at data this way, public health officials gain a detailed perspective on large-scale problems or growing trends.

As part of its Data Modernization Initiative, the Department of Health will launch the Enterprise GIS platform GeoHUB. In January 2023, users will be able to find training, locate and use geospatial data, view web applications and dashboards, and create their own GIS maps. The goal is to help programs use this adaptive technology to tell their own stories and make data-driven decisions.

Currently, a GIS professional must create maps for those who request them. The computer-based tools are used by epidemiologists, health consultants, environmental planners, and emergency management personnel to store, visualize, analyze, and interpret geographic data.

Whether it is shellfish safety information or the COVID-19 dashboard, DOH uses data and mapping to help better identify, monitor, predict, and respond to public health needs and then effectively share that information. According to Tonya Kauhi, GIS data analyst in the Enterprise Analytics and Geospatial Intelligence Office within the Office of Innovation and Technology, it is especially helpful in identifying areas of inequity. “Where people live and work can have significant correlations with their susceptibility to disease or injury,” she said.

During the COVID-19 response, DOH increasingly depended on GIS to track cases, hospitalizations, deaths, and vaccinations by county. Public health professionals continue to use the technology to better direct COVID-19 testing, services, supports, and vaccinations to socially vulnerable areas.

Initially, GeoHUB will be a place for internal staff to share sensitive data. However, the development team is looking at opportunities to securely share this resource with local health jurisdictions and Tribal partners. In the meantime, the team is working to develop processes, guidance, and training. Watch for further announcements starting in January.

“We are excited to offer this opportunity,” said Kauhi. “GIS continues to improve how people use and share geospatial data and related information.”
