Uvajanje sodobnega višinskega sistema v Sloveniji : Towards a new height system in Slovenia [PDF]
Geodetski Vestnik, 2007 The paper gives the outline of the modern physical height systems which are based on levelling and gravity surveys. Also, the Slovenian vertical networks are presented (vertical datum and height system) with all their drawbacks.

Bottom-up automata on data trees and vertical XPath [PDF]
, 2017 A data tree is a finite tree whose every node carries a label from a finite alphabet and a datum from some infinite domain. We introduce a new model of automata over unranked data trees with a decidable emptiness problem.

Formal deformation of curves with group scheme action [PDF]
, 2004 We study equivariant deformations of singular curves with an action of a finite flat group scheme, using a simplified version of Illusie's equivariant cotangent complex.

Development of Saudi continuous chart datum: Arabian Gulf case study
Geomatics, Natural Hazards & Risk, 2019 Global navigation satellite systems (GNSS) is widely utilized in marine applications for high accuracy vertical positioning. The errors introduced to charts by the present use of traditional shore-based discrete point chart datum (CD) can become a ...

Uplift and subsidence associated with the great Aceh-Andaman earthquake of 2004 [PDF]
, 2006 Rupture of the Sunda megathrust on 26 December 2004 produced broad regions of uplift and subsidence. We define the pivot line separating these regions as a first step in defining the lateral extent and the downdip limit of rupture during that great M_w ≈

New Approaches for Evaluating Lidar-Derived Shoreline [PDF]
, 2010 This study presents and compares two new methods of assessing the uncertainty of lidar-derived National Shoreline mapped by NOAA’s National Geodetic Survey: an empirical (ground-based) approach and a stochastic (Monte Carlo) approach.
