My interest in cartography has the following facets, each of which eventually will be a link:
Mathematical projections of the sphere used for making maps.
The interesting lives of the cartographers.
The development of our understanding of geography.
The explorers and their explorations who furnished the data for the maps.
The arts and crafts of actually producing maps.
The elaborate illustrations that accompanied some maps.
The techniques of navigation that were used, as knowing where you were was crucial.
