Q: What functionality remains when network connectivity is unstable or fails? Does event data remain locally cached so that users do not lose work/data added to the system up to that point? Is there an option for a field based or mobile server to provide layers of redundancy?
A: The program is built for worst case scenarios – what must be there, is there, internet or no.
The User’s GIS maps and data are stored on the local system. Thus, if the internet goes down, all the mapping functions perfectly. Preplans, databases, guidance, checklists, locating points of interest, finding fire hydrants, reports: These will all work.
Real time weather will be accurate up to the last moment of internet access and you can choose which weather source you trust most. You can also setup and use a mobile weather station without internet.
For MDT and C&C networked features (via ADASHI Server connection) are primarily Messaging, Incident Notification, all AVL features, and Internet Weather and the ability to receive new incidents
When the connection to the server is lost then the information on the screen is retained, map locations, units, notes, etc. For MDT the navigation to the incident will continue to work.
For Org Charts you will not be able to update any of the data until internet access is restored. It will retain the last changes you made until connection is restored.
Map Annotations will work for the commander as will his resource management; however, when dragging and dropping resources into place, field personnel will not receive that data until internet comes online. Similarly, the IC may draft and save their Incident Action Plan however sharing this document will require internet access.
Also, if a user sets up a remote local server (at the scene, for example) all communication will feed off that hub and they will have full AVL and Command and Control functionality.
