Coordinate Transformation

Coordinate transformation refers to the mathematical process of converting spatial data from one coordinate system or reference frame to another. This is essential when integrating datasets collected using different geodetic reference systems or when aligning local measurements with global positioning frameworks.

Coordinate transformations may involve changes between geographic coordinate systems (e.g., WGS84 to ETRS89), projected coordinate systems (e.g., UTM zones), or vertical datums (e.g., ellipsoidal height to mean sea level). The process can include translation, rotation, and scaling of spatial data to ensure geometric consistency.

Accurate coordinate transformation is critical in fields such as surveying, mapping, construction, and GIS, where precise spatial alignment affects the quality of design, planning, and decision-making.
