Business Problem Solved

We solved several problems:

How can we collect and use vast amounts of case and contact data?

How can we help our Incident Command staff execute large projects?

How do we better use data in our non-COVID work?

Our biggest project was the creation of dynamic spatial and data collection tools for our case and contact data investigations. Our investigators used it to interview residents and collect spatial data. Epidemiologists and GIS staff used the data to analyze, report on and map the virus in Pierce County. More than 150 staff members used this system each day at our peak, so we moved it from AGO to a Portal environment.

We also used GIS to provide planning and review tools to our Incident Command staff for things like:

Mask distribution.

Testing site creation.

Vaccine uptake.

Finally, we used lessons from our pandemic work to create sustainable processes for our use of GIS data, apps and systems in non-COVID programs across our agency.

Technology Implemented

ArcGIS Pro, Model Builder, ArcGIS Server (Portal), Survey123 Connect, ArcGIS Online (Dashboards, WebApps, Web Maps, Experience Builder, Survey123), Python to run automated tasks and Civic Lens for additional data backups.
