Thanks for the suggestion. Coincidentally someone else just suggested the same thing! I've added it to our Feature Requests list (number 77) - if anyone would like to see this added, please vote for it there.
It would be nice if the user could choose a defult map setting as I prefer the basic google maps initially then later look at topo.
Wow great thanks
As part of our continued investment to make plotaroute.com the best online route planner, we have introduced two new types of map to choose from:
In addition to adding these two new types of map, we've also made it possible to share routes using any of the available map types, so you can now choose from seven different types of map when plotting and sharing your routes. We hope to add further options in the future.
Lastly, we've changed the default map from Google's Street Map to Google's Terrain Map, as this shows more clearly where those all important hills are!
