From your point of view as a publisher, we understand you want a map that not only looks great at each of your product page sizes, but one which also includes the information relevant to the text in your publication, i.e. where possible, the extent of the map reaches the parts and modes of transport the author speaks about.
In this area we truly beat the competition. You have probably come across the problem where transport companies don't deal with individual requests for customisation. Most will provide a set of maps to a certain set of sizes but it is doubtful that any would allow you to change any aspect of their maps except for re-sizing in pro. The net result is that you end up with an image with something too small or something missing vital details at the cropped edge.

You've also worked hard to create a uniform brand throughout the product range and so a collection of maps with consistent quality and style fits in neatly with that policy. The fact that you are able to direct us to tailor the map to your exact needs gives you far greater choice and control than a 'take-it-or-leave-it' attitude a transport authority might have.
