Master Views Overview

In WebEOC, organizations can track individual incidents or combine multiple incidents in a common master view. Once configured by an administrator in the Master Views Manager, a user logged in to the master view can view the data from all sub-incidents together or filter the information to a single incident as needed. The ability to view the master view, along with its sub-incidents, is available only to those users with the appropriate group permissions for each incident that makes up the master view.


The option to track multiple incidents simultaneously yet separately, or rolled up into master views, means that a local EOC can track their own ongoing emergency while a district EOC combines several local incidents into a master view. At the same time, the State EOC could have a master view of all regional incidents. Each tier’s information can have a different level of detail based on the information requirements for each organization.

Users select which incident or master view to participate in when logging in to WebEOC. Master views are not themselves incidents; instead they are a view of information from selected incidents.

Logging in to a Master View

Master views and assigned sub-incidents are easily identified when logging in to WebEOC:

  • Master views and incidents that have not been assigned to a master view appear left-justified in the Incident drop-down list on the Login page.


  • Sub-incidents assigned to master views are grouped together immediately under the master view in the Incident list. Sub-incidents are preceded by three short dashes.

  • If an incident is assigned to more than one master view, it appears under each master view to which it is assigned.

  • A master view with no assigned sub-incidents does not appear on the Login page.
