Koordinaatistomittaus, known in English as coordinate measurement, is a fundamental concept in geometry and surveying. It involves determining the position of a point in space or on a plane by referencing a coordinate system. The most common coordinate system is the Cartesian coordinate system, which uses perpendicular axes.

In two dimensions, a point is located by its (x, y) coordinates, where x represents the horizontal distance from the origin along the x-axis, and y represents the vertical distance from the origin along the y-axis. In three dimensions, a third axis, the z-axis, is added, and a point is specified by (x, y, z) coordinates.

The process of coordinate measurement typically involves using specialized instruments. In surveying, total stations are widely used to measure angles and distances, which are then converted into coordinates. Other methods include Global Navigation Satellite Systems (GNSS) like GPS, which provide precise coordinates by receiving signals from satellites.

Coordinate measurement is essential in various fields. In cartography and geography, it is used to map locations and create geographical databases. In engineering and construction, it ensures accuracy in design, fabrication, and assembly of structures and components. It also plays a crucial role in computer-aided design (CAD) and Geographic Information Systems (GIS). The accuracy and precision of coordinate measurement are critical for the successful implementation of projects and the reliability of spatial data.
