As an off-road vehicle traverses a curved path driven by an operator, a data processor determines an error estimate between the points on the curved path and a generally circular perimeter about an estimated center point consistent with alignment of the curved path to the generally circular perimeter in accordance with a least squares algorithm or a modified least squares algorithm. The data processor or user interface provides an indicator to an operator of the vehicle that an arc length or angular displacement of the curved path with respect to the estimated center point is sufficient to estimate accurately the estimated center point and the radius of the generally circular perimeter if the determined error estimate is less than a threshold error.
