| He worked on geodesy but became interested in conformal map projections where he invented a quincuncial map projection using elliptic functions. |
| These are commonly considered to include plutology, with geodesy, geothermometry, seismology, and tectonophysics as subdivisions. |
| Even the most imaginative pioneers did not foresee the real impact of GPS on many fields of professional life, in particular my field, geodesy and surveying. |
| In the field of geodesy, however, Eratosthenes will always be remembered for his measurements of the Earth. |
| To my feeling, this is the most exciting GNSS development of the past 15 years within the field of geodesy, surveying, and geoinformation. |
| He proposed the method of triangulation and this work is the foundation of geodesy. |
