This session showcases the powerful role of GIS to solve county problems such as mental health accessibility, food insecurity, wastewater infrastructure, and public safety concerns. The Los Angeles County Department of Mental Health uses GIS to optimize service accessibility and decision-making, while a food access study in Riverside County highlights disparities in proximity to essential resources. Additionally, a Sonoma County wastewater study maps septic systems to identify sustainable treatment solutions. Lastly, learn how leveraging modern GIS can help propel your community forward as local efforts have pushed government capabilities and resources to extremes. Attendees will gain insights into geospatial applications that drive public health equity and environmental sustainability.
