Some mathematical assumptions for accurate transformation parameters between WGS84 and Nord Sahara geodetic systems

open access: yesJournal of Geodetic Science, 2023
The transformation of coordinates between different geodetic datums has been a common practice within the geospatial profession. Relating different geodetic datums mostly involves the use of conformal transformation techniques, which could produce ...

Numerical simulations of the nonlinear Molodensky problem [PDF]

open access: yes, 2013
We present a boundary element method to compute numerical approximations to the non-linear Molodensky problem, which reconstructs the surface of the earth from the gravitational potential and the gravity vector.

Algorithms for geodesics [PDF]

open access: yes, 2012
Algorithms for the computation of geodesics on an ellipsoid of revolution are given. These provide accurate, robust, and fast solutions to the direct and inverse geodesic problems and they allow differential and integral properties of geodesics to be ...

Some thoughts on the use of InSAR data to constrain models of surface deformation: Noise structure and data downsampling [PDF]

open access: yes, 2005
Repeat-pass Interferometric Synthetic Aperture Radar (InSAR) provides spatially dense maps of surface deformation with potentially tens of millions of data points. Here we estimate the actual covariance structure of noise in InSAR data.

Airy criterion and the ideal mapping of an ellipsoid of revolution onto a sphere

open access: yesJournal of Spatial Information Science
This paper addresses the problem of constructing an ideal projection of an ellipsoid of revolution onto a sphere based on the Airy criterion. General equations required to solve the problem are derived. In particular, the Euler–Urmaev system is obtained,
