Horizontalių žemės plutos judesių tyrimo metodikų ypatumai

Abstract

Specific features of earth crust horizontal movement determination methods and their application according results of repeated observations of geodetic networks are analyzed. Methodics of earth crust horizontal movement vectors determination by adjusting repeated observation differences in geodetic networks is presented. Possibilities of coordinates transformation application and specifics of earth crust horizontal movement investigation are discussed. Possibilities of simplification of coordinate transformation by valuing specific features of earth crust horizontal movements are analyzed. Was proved that results of coordinate transformation and results of network made of repeated observations adjustment without fixing initial points are identical. It was stated when the coordinate transformation methodics could be used for groups of permanent points determination. Application of various methods conditions, possibilities and specific features are analyzed.
