Machine translation, like DeepL or Google Translate, is a useful starting point for translations, but translators must revise errors as necessary and confirm that the translation is accurate, rather than simply copy-pasting machine-translated text into the English Wikipedia.
Do not translate text that appears unreliable or low-quality. If possible, verify the text with references provided in the foreign-language article.
You must provide copyright attribution in the edit summary accompanying your translation by providing an interlanguage link to the source of your translation. A model attribution edit summary is Content in this edit is translated from the existing German Wikipedia article at [[:de:Rauenberg (Trigonometrischer Punkt)]]; see its history for attribution.

The Rauenberg primary triangulation point is the starting point for the calculation of geographic coordinates of the Prussian main triangular mesh spatial reference system (Hauptdreiecksnetz). As the origin, it defines the location and orientation of the modern German triangular mesh spatial reference system in relation to the reference surface of a chosen Bessel ellipsoid.
Latitude and longitude (location) as well as the azimuth (orientation) are derived from astronomical measurements of the years 1853 and 1859.
