An emergency system can access a variety of situational data items, such as video streams, facility information, and present and past incident data. The emergency system identifies data items that may be relevant to a particular incident and provides the relevant data items in one or more user interfaces. For example, the emergency system identifies relevant data items based on the reported location of the incident and the type of incident. As additional incident information is received or entered by telecommunicators, the emergency system can further filter and surface data items likely to be useful in responding to the incident. Certain data items may only be permitted to be viewed by certain types of users, or under certain conditions. The emergency system may ensure that data items are provided to authorized users and in permitted use cases.
