The rectangular coordinate system, also known as the Cartesian coordinate system, is fundamental in surveying because it uses a grid-like structure to define the precise locations of points in two-dimensional space. This geometry allows surveyors to describe the location of points using pairs of numerical values, usually represented as (x, y) coordinates, where 'x' indicates the horizontal position and 'y' indicates the vertical position relative to a defined origin.

This method provides an efficient and straightforward way to calculate distances and angles between points, which is crucial for establishing control points, property boundaries, and various types of land development projects. Additionally, the Cartesian system supports various mathematical applications, such as trigonometry, making it versatile for professional surveyors in analyzing and interpreting spatial data.

In contrast, the other choices relate to distinct concepts in surveying. Measuring elevation changes pertains to vertical measurements and may involve elevation benchmarks or leveling techniques, while representing geographic information in 3D involves more complex spatial modeling and may utilize coordinate systems beyond just rectangular coordinates. Converting geographical data to numerical forms can refer to various methods of data analysis but doesn’t specifically address the essential characteristic of defining points with Cartesian coordinates, which is the core function of the rectangular coordinate system in surveying.
