> Maps and building plans are useful to the police but essential to fire services.
First of all thank you for the very good article. Having been a volunteer firefighter, I don't understand the requirement for online maps or building plans for fire services however. If you are on the attacking team, you will want *many* and *highly reliable* voice channels to communicate with the standby team and the command post. The command post may have a use for maps but then they sit in a lorry in the no-danger zone: They can *reliably* have the maps/plans on an offline medium such as a rugged hard drive. And they can (and probably will) guide you as they have the time to look up plans and think about ways of attack. In my (limited) experience, you don't have that time on the ground.
IMHO, most projects in this area are much too ambitious regarding "luxury" targets and forget the basics: It needs to work no matter what the environment conditions, how many users there are and what is the nature of the chaos around you. Streaming back video to the command post might be nice, but - again IMHO - is rather useless as the team inside is going to make most tactical decisions on its own based on what it sees, hears, smells and measures. We are trained for this and mainly need the channel to the CP to ask for reinforcements, supplies etc.
