Stimulating interest and encouraging youth participation for future sustainability

The test results show that the proposed method can mitigate the systematic errors of orthometric

height from e-GPS leveling efficiently. We present here the first part of the paper

Errors associated with GPS observations make it impossible to use a single receiver for geodetic, geodynamic and vehicle automation applications requiring centimeter or millimeter level accuracy.

With the advent of satellite imagery resolution, the satellite photogrammetry has become a new area of practice to handle mass data and been utilized in many areas with its low cost and short production time.

Geospatial Information Authority of Japan (GSI) is the governing institute on geodetic survey and mapping. It manages about 130,000 geodetic reference points in Japan and their survey results are consistent with the International Terrestrial Reference Frame. The recent development of GNSS technology led to more than 1,200 GNSS-based control stations with operation system called GEONET as new geodetic reference points.
