VISTA Web Mapping – BC Vital Statistics Agency

The British Columbia Vital Statistics Agency (VSA) stores data on medical events (births, deaths, and others) in an analytical data warehouse (VISTA). The VISTA system was already capable of creating tabular and chart based reports, when VSA asked Refractions Research to add an on-the-fly mapping capability to the system.

Refractions integrated a mapping system based on the Mapserver open source web mapping engine into the existing VISTA infrastructure. The new system acted as another “view” of the data, so any data query can now be viewed as a table, a chart, or a colorful thematic map. The enhanced system is capable of creating both web-based maps, and equivalent PDF maps as well. The PDF mapping capability replaces an existing manual process for creating plot-ready maps with a one-click on-the-fly process.
