Abstract
Projecting the Earth on a flat map is one of the most important ways people use to learn
about the planet. Throughout history, a large variety of world maps have been designed for
different purposes, such as to learn about countries or to navigate a long voyage. However,
such maps can never be perfect due to the contradictory properties. Approaches have been
proposed in order to reduce distortion, but cartographers have not yet considered how to produce
a continuous projection which can best preserve important regions. In this thesis, we design
and implement two systems, one automatic and one interactive, to produce projections that can
preserve selective regions better without making the map discontinuous. The systems allow
users to highlight their preference in making a useful...[

Projecting the Earth on a flat map is one of the most important ways people use to learn
about the planet. Throughout history, a large variety of world maps have been designed for
different purposes, such as to learn about countries or to navigate a long voyage. However,
such maps can never be perfect due to the contradictory properties. Approaches have been
proposed in order to reduce distortion, but cartographers have not yet considered how to produce
a continuous projection which can best preserve important regions. In this thesis, we design
and implement two systems, one automatic and one interactive, to produce projections that can
preserve selective regions better without making the map discontinuous. The systems allow
users to highlight their preference in making a useful map tailored to them. Our tools can
generate a map according to these settings. We also conducted a user study to evaluate our
systems and compare our results with existing maps.
