URL copied Share URL
  1. [coordinate systems, spatial analysis] A type of affine transformation (a geometric transformation) used to transform coordinates between coordinate systems. A Helmert transformation includes translation, rotation, rescaling, and a skew component that allows for the correction of systematic errors between coordinate systems. The Helmert transformation is named for the German mathematician and geodesist Friedrich Robert Helmert (1843-1917).
