The Netherlands Geodetic Commission (NCG, part of the Royal Netherlands Academy of Arts and Sciences; KNAW) and Geo Information Netherlands (GIN) has organized a one day seminar 'Geo-information and Computational Geometry' on 14 November 2005. The seminar was held in the Blauwe Zaal in the Wentgebouw, known as the 'De Ponskaart', at Utrecht University, The Netherlands.
The main purpose was to show several different aspects related to spatial data structures and algorithms, which are normally not directly visible to the GIS end-users. The seminar was intended for a more technology-oriented audience, though the presenters are asked to find right balance not explaining all (basic) details and presenting the technology in a comprehensible manner.
