In this presentation, we review current challenges and future opportunities as geospatial data and processes are applied to the field of public health. Of particular importance, we review mechanisms where uncertainty may be introduced and opportunities that exist to reduce such issues. Examples include the use of multiple reference data sources to reduce geocoding errors, and the use of hospital discharge information to understand residential mobility and its impact of clustering and accessibility metrics. We also discuss best practices to communicate spatial and spatio-temporal uncertainty
