The Enterprise Virtual Operations Center (EVOC) Is the result of a multi-year process that the city of Anaheim and its IT partner EDS have undertaken to integrate data and communications to improve emergency response. The vision is to provide better situational awareness to decision makers in an easy-to-use application that brings together information from applications that were previously stovepiped, explains David Brown, an EDS employee and the EVOC project manager for Anaheim. Despite agencies' efforts to improve sharing real-time data, portals or Intranets linking multiple emergency response agencies and jurisdictions are still rare. Many regions have tried to create data warehouses to pool information, but they often run into infighting between agencies about how and when data can be accessed. As with any data integration project, some agencies that own data are concerned about how it is going to be used and protected. Brown said they have a governance structure set up to determine these things.
