I need about 20 or so simple locator maps for a guide book that I've written. The quote from a local cartographer was $400 per map (actually, $400 and up -- whew!), which made me wonder what cartography software might be available for Macs. The maps would not be complicated -- just selected roads, towns, larger rivers (maybe), and then the specific sites for the book. Any suggestions would be appreciated -- thanks in advance!
