Which datum is based on the Clarke Spheroid of 1866 and has an origin point at Meades Ranch in Kansas?

The National Datum of 1927 (NAD 27) is indeed based on the Clarke Spheroid of 1866, which was a geodetic model used for many years in North America. The significance of the origin point at Meades Ranch in Kansas is crucial because this is where measurements were made to establish a standard reference point for the entire continental United States. This datum was widely utilized for surveying and mapping across the country and served as the foundation for several other surveying techniques and practices.

NAD 27 has since been largely replaced by NAD 83, which is based on a more modern ellipsoid and provides a consistent reference frame for the entire globe. However, when specifically examining the characteristics mentioned in the question, NAD 27 fits perfectly due to its historical context and the geodetic foundations established at Meades Ranch. This understanding helps to clarify its relevance in the evolution of geographic data systems and survey methodologies within the field.
