projektsioonitegurid

Projektsioonitegurid, also known as projection factors, are mathematical constants used in geodesy and surveying to convert measurements made on the Earth's surface to a plane, such as a map or a chart. These factors account for the Earth's curvature and the distortion that occurs when projecting a three-dimensional surface onto a two-dimensional plane. The most common projection factors include the scale factor, which adjusts for the difference in scale between the Earth's surface and the map, and the convergence factor, which corrects for the angular distortion caused by the projection. Other factors, such as the meridian factor and the parallel factor, address distortions along meridians and parallels, respectively. The choice of projection and the corresponding factors depend on the specific requirements of the mapping project, such as the area to be mapped, the desired accuracy, and the purpose of the map. By applying these factors, cartographers can create more accurate and useful maps that represent the Earth's surface with minimal distortion.
