  • Knowledge base
  • Geodesy and reference systems

The Delft Method for Adjustment and Testing, also known as the Delft School, is a methodology within geodesy developed at the Delft University of Technology between 1930 and 1980. Under the leadership of Jacob Menno Tienstra and Willem Baarda, methods were formulated that radically improved the quality of geodetic measurements.
