Angular data refers to data that is directional and involves angles or rotations. Some synonyms for angular data include vector data, directional data, rotational data, and bearing data. Vector data is a term commonly used in geography and geology, and it represents the direction and magnitude of movement. Directional data is used in statistics to describe data that is not distributed symmetrically. Rotational data is often used in engineering and physics, and it represents the angle or rotation of different components in a system. Finally, bearing data is used in navigation and surveying, and it represents the direction between two points on a map.
