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.
