GA airport visual database?

Hi all...

Trying to get a feel of how many airports and where they are located which have
different services, types/lengths of runways etc etc...

Now, I am familiar with Airnav....and its pretty easy to query the database and
get a list based on criteria and distance from the chosen airport....

But what I'd like to see is the bigger picture......say I want to look at the
whole state of Alabama....or maybe even a couple of states....

And then say I require a 2500 foot or longer paved runway and avgas.....

Is there a website where I could get a graphical display that would show the
query results with something like a map of the chosen state/area with say red
dots that show the general locations of airports that meet my requirements?

Anybody know of anything similiar online?

take care
