Calibration of geodetic apparatus and its property analysis;

Since 60 s in the 20 Century China has carried out 5 times(1966,1975,1992,1998 and 1999 respectively)geodetic campaigns for the determination of the height of the world highest peak—by itself or together with foreign countries.

Besides,an application framework model of geodetic surveying metadata based on RDF is built.

Ill-conditioned problems are widely existed in geodetic surveying.

In the meantime,the data of geodetic measurement,geological investigation and test are also analyzed,and the analytic results show that the local motion of Fushun segment on Hunhe fault is caused by coal extraction.

Hence when the displacements of observational stations on the Earth surface are studied with geodetic measurements, the derived displacement patterns depend on adopted reference frame.

Study on the high accuracy geodesy monitoring automation system;

Application of wavelet analysis in geophysics and geodesy;

This paper summarized the newest progress of the Science and Technology of Surveying & Mapping discipline and five sub-discipline,include geodesy,photogrammetry and remote sensing,cartography and geographic Information engineering,engineering surveying and marine surveying.

This paper describes the principles of a differential GPS positioning system and offers the converting formulas, which can be used in computers, between the geodetic coordinate used in the GPS and plane rectangular one in the geodetic survey.

In this paper author concisely summarizes a few common map-projection transforms and the result conversion of geodetic survey and gives their computer algorithm and the source program.

On the one hand, the service of the Geodetic Survey Information System faces to application directly nowadays, and therefore it s hard to be maintained when the users demands change.
