2 Projected coordinate systems Projected coordinate systems are any coordinate system designed for a flat surface such as a printed map or a computer screen. Topics in this chapter include: • Characteristics and types of map projection • Different parameter types • Customizing a map projection through its parameters • Common projected coordinate systems 9
