County Health and Human Services


After recent standards enacted by California Department of Health Care Services (DHCS) were announced in early 2018, VESTRA performed Network Adequacy Mapping services and provided training for a number of California counties. This required county health providers to demonstrate accessibility of services for mental health beneficiaries measured by time, distance, and timely access.

The projects involved licensing and installing ArcGIS Pro, Network Analyst extension, and Street Map Premium Extension when necessary. VESTRA then performed the mapping on-site for the counties.

Mapping involved geocoding beneficiary and provider locations, generating heat map views, and generating drive-time and distance buffers using the Network Analyst extension. The projects also included creating documentation and/or providing training for County staff to enable them to repeat the process for ongoing quarterly reporting.

California Office of Statewide Health Planning and Development

VESTRA has been supporting the California Office of Statewide Health Planning and Development (OSHPD) as they work to develop a statewide enterprise GIS for quality policy analysis, allocation of funding resources, and to aid in the monitoring of healthcare quality throughout the state. The Healthcare Atlas also includes emergency departments and ambulatory services. Work was performed to re-engineer the mapping applications in order to interface with a new data warehouse that dramatically expand the GIS user interface using ASP.NET. The internal OSHPD Website receives live earthquake data to assist OSHPD’s Emergency Operations Center (EOC) in providing support and regional coordination to hospitals affected by an earthquake. This EOC portion of the application received a “Best of California” award in 2008.

VESTRA developed the Putting Youth on the Map (PYOM) Data Analysis Viewer for the UC Davis Center for Regional Change (CRC).  The CRC wanted to visualize and analyze a number of well-being and vulnerability indices affecting California’s youth.  VESTRA used Esri’s ArcGIS API for JavaScript to build a mapping application that displayed up to three maps side-by-side that can be used to compare various indices.  Each map can display a different trend or index which when compared to indices in the other maps, provides an understanding of trends and patterns that can affect change in policy and decision making.  The extent and position of the three maps can be synchronized to assist in comparing the indices on an area by area basis.  Social media integration was added by allowing users to share a printed map or a URL that would launch the app with a specific area of interest being displayed.  In addition to application development, VESTRA provided CRC staff with support for the configuration and publishing of PYOM map services using ArcGIS for Server.  The PYOM application required specific functionality only available in ArcGIS for Server 10.3. VESTRA assisted CRC in upgrading from ArcGIS for Server 10.2 to ArcGIS for Server 10.3.1.

Most recently, VESTRA worked with UC Davis to develop, test, and implement functionality to accommodate use of the PYOM by mobile and tablet devices. The goal of the project was to provide a well-functioning user interface for the PYOM that scales appropriately from desktops down to mobile and tablet devices. The development process included porting the PYOM application into the Twitter Bootstrap framework, and making revisions to the PYOM application that enabled responsive behavior, allowing similar functionality between desktop, mobile or tablet device browsers.
