INPREP aims to prepare responders better, so more lives can be saved during natural disasters and crises. The principal goal is to improve collaborative response planning. To do so, IN-PREP is trialling a new training platform for CP agencies and first responders. It is an end-to-end, interoperable Mixed Reality Preparedness Platform featuring a multiplicity of modules to support dynamic scenario building, disaster-modelling, multi-agency command & control and sharing of the operational picture. Agencies using IN-PREP will be able to plan, train and collaborate better than even before.
