Summary
In this article the local, nation-wide and world-wide geodetic control systems will be treated as well as the advantage and limitation of the geodetic adjustments of large triangulation nets, and the additional observations needed before the second adjustment of the European triangulation. The fundamental significance of the gravimetric method for establishing the world-wide geodetic system, for the control of small scale maps beginning from 1∶100.000 for determining of the super control points for the long-range triangulations and particulary for checking the earth's dimensions will be emphasized.
Zusammenfassung
In diesem Aufsatze werden die lokalen, nationalen und weltweiten geodätischen Systeme behandelt, vor zu grossem Vertrauen in die Ausgleichsrechnungen gewarnt, einige Vorbedingungen für gute Ausgleichung der Europäischen Triangulation erwähnt, die Bedeutung der gravimetrischen Methode für das weltweite geodätische System, für Kontrolle der Karten von kleinem Masstabe (nicht grösser als 1∶100.000), für Berechnung der Erddimensionen und für Gründung der Superkontrollpunkte für die grossen Triangulationen betont.
