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.
ADASHI Client networked features (via ADASHI Server connection) are primarily Messaging (&IM), Incident Notification, all AVL features, and Internet Weather. Command and Control Org Charts are additionally stored on server. Installing local ADASHI servers for such “network down” situations provides redundancy and supports switching to a field based server and network.
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.
