A vertical coordinate system defines the origin for height or depth values. Like a horizontal coordinate system, most of the information in a vertical coordinate system is not needed unless you want to display or combine a dataset with other data that uses a different vertical coordinate system. geographic coordinate system (GCS) uses a three-dimensional spherical surface to define locations on the earth. A GCS is often incorrectly called a datum, but a datum is only one part of a GCS. A GCS includes an angular unit of measure, a prime meridian, and a datum (based on a spheroid).
Datum is, from its Latin origin, a singular form of data, and may refer to a single item of data. 1 Singular data point. 1  Geodetic datum, a standard position or level that measurements are taken from in geographic surveying. 2  Datum reference, in carpentry, metalworking, needlework, geometric dimensioning and tolerancing. 3  Chart datum, level of water depth on a nautical chart. Datum or datum point, a (possibly arbitrary) reference baseline or point from which scientific measurements are made (from a Latin meaning of datum as a given, i.e. an accepted fact)
