What is a geodetic network?

A geodetic network is fundamentally defined as a set of points with known positions, which can accurately represent locations on the Earth's surface. These points are typically established through precise measurements using geodetic methods such as triangulation, trilateration, or GNSS (Global Navigation Satellite System) technology. This network serves as a reference system for various applications, including mapping, surveying, navigation, and geospatial data analysis.

Moreover, geodetic networks are crucial for maintaining a consistent positional reference that allows for the integration of data from different sources, ensuring that measurements taken across various geographical locations remain accurate and comparable. The points in a geodetic network are often used to monitor changes in the Earth's crust, support infrastructure development, and assist in scientific research.

While the other options mention forms of organization or infrastructure, they do not capture the essence of geodetic surveying and positioning. A series of connected roads pertains to transportation infrastructure, communication towers relate to telecommunications, and latitude and longitude lines help to define locations but do not constitute a network in the context of measuring and understanding the earth. Therefore, the appropriate definition of a geodetic network is accurately represented by the idea of a set of points with known positions.
