Free and Open for Government Agencies

Designed for Cross-Jurisdictional Coordination

Wildfires, floods, and other disasters often cross county lines. OEZ enables agencies to maintain a consistent view of evacuation zones across jurisdictions, improving coordination between emergency managers, law enforcement, and fire agencies.
