A horizontal datumField is a reference system used to define positions on the Earth's surface using latitude and longitude. It's essentially a coordinate system that helps pinpoint locations geographically. This system relies on a mathematical model of the Earth's shape, often an ellipsoid, and a specific anchor point.

A vertical datumDescription is a reference surface used to define vertical positions, essentially serving as the "zero point" for measuring elevations and depths on Earth. It's crucial for consistent and accurate height measurements in various fields like surveying, hydrography, and navigation. 

Time Zone

TheSets the local time zone for the project’sproject location. This helps timestamp data and coordinate updates across time-based processes.
