Actually, from what I've learned, the reason alot of maps are incorrect is because they were drawn with bad data. I've noticed that my city has alot of streets on maps that don't exist or that are incomplete, and after asking around, I've found that this seems to happen for a couple reasons. In some cases the maps may have been drawn based on city plans. A right-of-way may exist where the road is shown on the map even though the road was never built or completed. In other cases roads have been changed or removed, and the maps have never been updated.
I had read the same thing shortly after recieving my HAM license. There are a few other limitations places under Part 15 operators. While its been a few months since I was considering part 97 operation, I seem to remember that the FCC also limits power and gain within Part 15 operation. For those who don't know, Part 15 defines the rules for unlicensed usage such as in home or business networks. Part 97 grants a different set of licensed rights to HAMs. Anyway, I believe the power cap for part 15 was 500mw, but I can't remember the gain cap. Seems to me it was something like 4db... It was definitly lower than what is possible with a cantenna.
