DEM delivers better approximate AHD heights on public record
Jonathon Smith and Dr Volker Janssen
This paper outlines how a state-wide Digital Elevation Model (DEM) has been used to deliver better approximate Australian Height Datum (AHD) heights, yielding a homogeneous dataset of known provenance and verifiable quality across New South Wales, Australia ... [more]
Generalized orthogonalization an elegant solution to the least squares problem
Prof. Joël van Cranenbroeck
The generalized orthogonalization does not require the formation of the normal equations and is therefore numerically more stable than the conventional method ... [more]
