My phone works fine in the rain. The touchscreen is garbage, because it can't differentiate my finger from a puddle on the screen. Granted, there are pressure sensitive touchscreens out there. If you want a good map that you can take notes on, you'll need a custom app. In my experience, writing on screens is very fussy business. So you might be able to a custom app, custom hardware, maybe spending thousands per unit.

But, paper. I mentioned a brand name. It's wonderful stuff, nothing like the paper you're thinking of. This solution costs a few bucks per person.

Edit: this "rain" crap is a digression from the "fire" problem. I don't have experience there, but I imagine "the electric infrastructure and cell towers burnt down" is more of an issue... again, paper and pencil wins.

WRT. paper vs. touchscreens and fire, I imagine two extra factors come into play. One, protective equipment may not play well with touchscreens (are there capacitive screen-friendly pads for gloves that won't burn off?). Two, heat in general. Phones and tablets don't like it all that much, and can easily start behaving weirdly and/or shut down when being used in a car in summer, much less next to an actual fire.
