thank you very much for your answer, yes, i'm realizing that i'm about a decade too late to be getting into this "hobby" the way i want, i'm finding a lot of links from 2008 where the whole forum websites no longer exist, never mind the links referenced from specific subject that are now missing.
can i ask one last question, this statement to me seems like it would do the greatest good for me: To make your own transparent road overlay, you could just use openstreetmap data, because then i can load my 24K TOPO map with a latest road overlay and this will give me exactly what i want.
what would be the relevant tutorial to do *explicitly* this task, to just create an .img overlay?
