Quadrants

FME also allows coordinate systems to be measured in quadrants other than the usual one where X increases to the east and Y increases to the north. The QUAD directive in a coordinate system definition is used to set the orientation of the coordinate system.

This directive takes an integer value from -4 to 4. 0 or 1 indicate the normal right-handed Cartesian system, where X increases to the east, and Y increases to the north. This is the default quadrant.

Quadrants are numbered counterclockwise; therefore:

2

1

3

4

A negative value will cause the axes to be swapped after the appropriate quadrant is applied.
