A projected coordinate system defines a position in (x, y). x refers to easting and y is northing. Easting and northing coordinates are commonly measured
A) in centimetres based on an orthogonal Cartesian coordinate system with the lower-left corner of a map as the origin
B) in centimetres based on a datum
C) in decimal degrees based on a datum
D) in metres based on a datum

Question

Quizplus · Accepted Answer

Projected coordinate systems commonly use meters as the unit of measurement and are based on a datum such as WGS 84 or NAD 83. Choices A and B are incorrect as they mention centimeters which is not a common unit for projected coordinate systems. Choice C is incorrect as decimal degrees are used in geographic coordinate systems not projected coordinate systems.
