Conclusions (II) - a view beyond 2015… Ministry of the Interior and Local Affairs NRW, Germany � CORS GNSS (SAPOS®) is the fundamental measurement technique to determine 3- or 2D- coordinates and heights. � an accurate 1 cm-geoid is usable � new measurement techniques will gain importance, if they are a) inexpensive (less men power), b) fast in the field and in general c) contact-free. ���� classical point fields have less (no) importance __________________________________________________________________________________________________________ The Geodetic Infrastructure in Europe – today and tomorrow - Sweden, Umeå 22-23 June 2011

Conclusion I – What´s the NRW-approach? GNSS for 2D-Position Geodetic infrastructure of today Geodesy in Change Remote sensing for DEM and DOP Reduction of the reference point field (no trigonometric point field) Ministry of the Interior and Local Affairs NRW, Germany 3cm-gravity field (quasi-geoid) from GPS-leveling __________________________________________________________________________________________________________ The Geodetic Infrastructure in Europe – today and tomorrow - Sweden, Umeå 22-23 June 2011
