reprojektív

Reprojektív is a term used in cartography and geodesy to describe a specific type of map projection. It refers to a projection that is derived from an existing projection through a process of transformation. This transformation can involve mathematical adjustments to alter scale, shape, or area representation of the original projection. Essentially, a reprojection takes a map that has already been projected and applies another projection to it.

The purpose of reprojection is often to adapt a map for different uses or to improve its properties for a specific region or application. For example, a map initially created for global coverage might be repro jected to a more suitable projection for a particular country or continent, optimizing its accuracy for that area. Reprojections can also be employed to convert between different coordinate systems or datums, ensuring compatibility and consistency in geospatial data. The process involves applying the mathematical formulas of the new projection to the coordinates derived from the original projection.
