The NCG and the NCG committees regularly organise symposia and study days where knowledge and insights in the field of geodesy and geo-information are presented and discussed and where research questions are formulated. In the past, the lectures have often been published in one of the two NCG series.
The annual symposia are free of charge and intended for researchers and students from Dutch universities, academies, companies, government agencies and institutes active in the field of geodesy, geoinformatics and geoinformation sciences and for professionals from the field. The symposium is aimed at active researchers in the field, including PhD students and postdocs, with the aim of exchanging and discussing research results and activities on various themes.
The Baarda lecture is held annually during the plenary part of the symposia. Every two years, het Prof. J.M. Tienstra Prize is awarded. The winner will give a presentation about his or her work. In session meetings, participants briefly present their PhD research or other research in which they are involved.

NCG Symposium (program available here)
This edition of the symposium featured a special event, “Navigating the Geodetic Landscape: Honoring 45 Years in Science by Peter Teunissen, Professor of Mathematical Geodesy and Positioning,” organized by Delft University of Technology, the NCG, and IUGG Netherlands (photo left).
The symposium also included the annual Baarda Lecture, delivered by Prof. Todd Humphreys (Professor of Aerospace Engineering in the Department of Aerospace Engineering and Engineering Mechanics at the University of Texas at Austin) (photo right).
The symposium also included a special interactive session on recent topics in geo-information science, the future of the NCG and its committees, education, and career opportunities. Active researchers (including PhD candidates, students, and postdocs) presented their work in workshops. Martin Salzmann and Lennard Huisman (both working at the The Netherlands’ Cadastre, Land Registry and Mapping Agency) gave a presentation on the state of affairs of the geodetic infrastructure in the Netherlands (NSGI), which is recognized by the Land Registry, Rijkswaterstaat, and the Hydrographic Service of the Royal Dutch Navy.
