Ephemeral Map Layers
Definition
Ephemeral Map Layers are temporary GIS layers that represent time-sensitive, short-duration phenomena like wildfires, floods, construction zones, or event routes. They support real-time decision-making and are typically removed or archived once the event concludes.
Application
Emergency teams add ephemeral layers to display evacuation zones. Cities publish temporary road closures or festival boundaries. These layers often rely on live feeds and mobile mapping. GIS platforms enable quick creation and sharing of ephemeral content for situational awareness.
