The accuracy of maps on Attovia have remarkably little influence on most travel. The need for accurate passages between continents is solved thanks to those passage ways being impassible and other continents entirely theoretical. Roadways in the civilized core of Attovia make over land travel quite navigable and those rivers that host substantial trade have plentiful landmarks both geological and urban.
Few Wizards are interested in the study of Workings that might improve the accuracy of cartography and land survey’s since no one is willing to pay for related research. Hence we see that most Attovian maps are simplistic and generally quite inaccurate, but the creators and purchasers are aware of these flaws in most scenarios.
The most common maps actually produced and sold in higher quantities are regional and city guides which are often substantially more accurate than greater scales. Often these kinds of cartographers can make a tidy sum reaching out to business owners who will pay a small fee to have their establishment included. Higher prices mean more prominent text or even a place on the maps legend.
