DOPx is a direct multiplier of the standard error in obtaining the standard deviation for the eastward velocity estimate from the least squares best fit. DOPx and DOPy are commonly used to obtain the geometric dilution of precision (GDOP = sqrt(DOPx^2 + DOPy^2)), a useful metric for filtering errant velocities due to poor geometry. maxValue: minValue: units: unknown dimension: (MD_Band) sequenceIdentifier: MemberName: aName: DOPy attributeType: TypeName: aName: float descriptor: The latitudinal dilution of precision (DOPy) represents the contribution of the radars' configuration geometry to uncertainty in the northward velocity estimate (v).
