Virtual Observation Method and Precision Estimation for Ill-Posed Partial EIV Model

AbstractThis paper presents a method for solving the ill-posed problem of the partial error-in-variables (EIV) model and a precision estimation method based on a second-order derivative approximate...

期刊介绍： The Journal of Surveying Engineering covers the broad spectrum of surveying and mapping activities encountered in modern practice. It includes traditional areas such as construction surveys, control surveys, photogrammetric mapping, engineering layout, deformation measurements, precise alignment, and boundary surveying. It also includes newer development such as satellite positioning; spatial database design, quality assurance, and information management of geographic information systems; computer applications involving modeling, data structures, algorithms, and information processing; digital mapping, coordinate systems, cartographic representations, and the role of surveying engineering professionals in an information society.
