</div>Possibly. I haven't studied their terms in detail because I haven't<br>
run into a situation where I would violate them. But, yes, one should<br>
do their own due diligence on what is allowed and what is not.<br>
<br>
Anyway, the original thread is on how to make maps and data available<br>
without Internet access. I hope the OP now has enough information to<br>
know this is possible and relatively not-that-difficult.<br>
