This enumeration informs about the coordinate units in use. It can only be set before importing a dataset.

 

Geographic coordinates:

cuRad (radians, -pi - +pi, -pi/2 - +pi/2)

cuDeg (degrees, -180 - +180, -90 - +90)

cuGrad (grads, -200 - +200, -100 - +100)

 

Projected coordinates (SI units):

cuMm

cuCm

cuDm

cuM

cuKm

 

Projected coordinates (non-SI units):

cuPoint

cuInch

cuLink

cuFt

cuSurveyft

cuYard

cuChain

cuRod

cuMiles

cuNmi

cuUnknown

 

Data using geographic coordinates are checked during import for valid range.

 

By far the most usual ones are cuDeg and cuM.
