Internally, what elements make up a Geopoint?

A Geopoint typically represents a location in a three-dimensional space and is characterized by its geographic coordinates. The essential elements that define a Geopoint are latitude and longitude, which pinpoint a specific location on the Earth's surface. However, in addition to these two dimensions, altitude is also included to provide a complete representation of that point in three-dimensional space.

By incorporating altitude, one can define not just where a point is located horizontally (latitude and longitude) but also its vertical position, making it useful for applications that require spatial accuracy, such as mapping, navigation, or even drone applications. This comprehensive definition allows developers and engineers to work with data that requires full spatial context, such as in geographic information systems (GIS) or IoT applications where altitude may impact sensor data or positioning.

Given this understanding, the inclusion of altitude along with latitude and longitude makes the selection of latitude, longitude, and altitude the correct answer.
