For all those interested, I managed to import and scale Siegfried's map with his permission this morning into a free version of CAD. I've done a load of testing using the trader tool for distances etc. The only real error is probably the original inaccuracy in the cartography to produce. I must stress there is NO complaint here, as I love the idea that the accuracy of the map probably truly reflects the time period. However for all those interested its a simple thing and with all the tools we wish for as Koltes has already put out in his map tools thread. I cant wait to start using. I am more than happy to share the CAD file we everyone after first checking this is OK with Siegfried. Below is a sample of result testing using 3 point data from the port trader tool. Location Port Morant, points used Tiburon, Portillo, Pedro Cay.
