Grid Model for High-accuracy Coordinate Transformation of China Geodetic Coordinate System 2000 [PDF]

open access: yesJournal of Geodesy and Geoinformation Science, 2019
After implementing CGCS2000, establishing grid models for high-accuracy coordinate transformation which are mainly used to transform border lines and coordinate grids of topographic maps becomes an important issue in mapping applications. Consequently, a

Določitev položajev cerkvenih zvonikov v koordinatnem sistemu D96/TM ( = Position determination of church belfries in the D96/TM coordinate system) [PDF]

open access: yesGeodetski Vestnik, 2018
In the old coordinate system, church belfries often served as reference points in detail surveying. Consequently, their coordinates were regularly maintained in the geodetic databases of the old coordinate system.

Coordinate systems, geodetic datums and coordinate transformation

open access: yesVojnotehnički Glasnik, 1999
This article makes an effort to define some types of coordinate systems and geodetic datums. Also it points out the importance of making connection between the local datum in which all state maps are prepared and the geocentric datum in which GPS works.

Coordinate transformation and its uncertainty under consideration of a non-orthogonal coordinate base [PDF]

open access: yes, 2021
Nanopositioning and nanomeasuring machines are 3D coordinate measuring systems with nanometer precision at measurement volumes in the cubic centimeter range. The coordinate base is formed by an interferometer system with a common mirror corner.

A Novel High-Squint Spotlight SAR Raw Data Simulation Scheme in 2-D Frequency Domain

open access: yesRemote Sensing, 2022
Raw data simulation is the front-end work of synthetic aperture radar (SAR), which is of great significance. For high-squint spotlight SAR, the frequency domain simulation algorithm is invalid because of the range-azimuth coupling effect.
