Abstract
The evolution of the mathematical foundations of maps in school geographical atlases, especially in 19th and 20th century, was one of the elements of the perception of progress in cartography by the didactics of geography. The biggest changes, ongoing also today, concerned cartographic projections used to maps design.
The evolution of the geographical coordinate system is a part of this process and the basis of the theory of cartographic projections. In the paper there are described changes concerning the location of the Prime Meridian and the method of the description of longitude – elements necessary for the construction of the grid of meridians and parallels. These changes are presented on the basis of analysis of 665 atlases, what means all editions of Polish school geographical atlases between 1771 and 2012 identified by the author.
The evolution of the mathematical foundations of maps in Polish school atlases over more than two centuries is an example of assimilation of the newest trends and scientific researches that takes place between science and education.
