Basics of Map Projection
This chapter focuses on the key concept of map projection. The sequence
of mathematical operations which leads to preparation of maps is explained
through a sequence diagram. The important map transformations or map
projections and their characteristics are explained. Some of the important ap-
plications of map projections are tabulated along with their properties. The
classification of map projections from different mathematical perspectives and
cartographic aspects is given. This chapter deals with the basic concepts of
map projection and answers generic queries such as ‘What is map projection?’,
‘Why is map projection required?’, ...
