Which map projection is NOT used to transform latitude and longitude into x (Easting) and y (Northing) coordinates?

• A. Universal Conformal Conical Mercator
• B. Mercator
• C. Transverse Mercator
• D. Plate Carrée

Answer: (A)

Transforming latitude and longitude into x (Easting) and y (Northing) coordinates requires a projection that converts spherical coordinates to a plane. Mercator does this by mapping longitude to x and latitude to y with conformal, angle-preserving properties. Transverse Mercator performs a similar conversion in a rotated orientation, which is ideal for tall, narrow areas and underpins systems like UTM. Plate Carrée directly assigns x from longitude and y from latitude, giving a simple rectangular grid. There isn’t a standard, widely used projection named Universal Conformal Conical Mercator for converting lat/long to plane coordinates; therefore this option isn’t used for this purpose. The others are valid methods for producing x and y from latitude and longitude.
