PCTrans network version

PCTrans is a program for geodetic and hydrographic computations. The network version is intended for network computers at companies and government institutions. There is also a PCTrans standalone version.

Download the PCTrans network version on the website of the NSGI.

NSGI is a partnership between Kadaster, Rijkswaterstaat and the Netherlands Hydrographic Service on the Geodetic Infrastructure in the Netherlands.

You can use the program for the following computations:

  • datum transformations;
  • chart projections;
  • geodetics;
  • loxodromes;
  • areas, taking into account the Earth’s curvature.

PCTrans also calculates the differences between mean sea level and the chart datum, for positions on the Netherlands Continental Shelf and in internal waters. Calculations of variations and inclinations of the Earth's magnetic field is also possible.
