The second precise levelling network of Peninsular Malaysia [PDF]
, 2009 The measurement of Second Precise Levelling Network (PLN) for the Peninsular Malaysia which was completed in 2000 by Department of Surveying and Mapping Malaysia (DSMM) is set to replace the First Order Levelling Network of 1967. The new network consists

Inferences of mantle viscosity based on ice age data sets: Radial structure [PDF]
, 2016 We perform joint nonlinear inversions of glacial isostatic adjustment (GIA) data, including the following: postglacial decay times in Canada and Scandinavia, the Fennoscandian relaxation spectrum (FRS), late-Holocene differential sea level (DSL ...

Geophysical Monograph Series, Page 263-304., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

A Method to Construct Depth Datum Geodesic Height Model for GNSS Bathymetric Survey
Journal of Marine Science and Engineering, 2022 Water depth measurement requires the establishment of one or more tidal stations in the survey area for synchronous water level observation, and finally the water depth is estimated to the depth datum.

Referencing regional geoid-based vertical datums to national tide gauge networks
Journal of Geodetic Science, 2012 The objective of this study is to investigate the best means for referencing a regional geoid-based vertical datum to a network of tide gauges. In this study, a network of 27 tide gauge stations scattered along the coasts of Canada are used in order to ...

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.
