Reference Frame in Practice Seminar
29-30 July 2017, Kobe, Japan
The list of presentations delivered over the 2 days were –
- Prof. Geoffrey Blewitt: Geodetic
Reference Frame Theory
Overview – Provision of fundamental theory with respect to global
velocity field determination; the importance of sourcing and sharing
GNSS geodetic data with an emphasis on the potential benefits to
participating countries from a scientific, economic and social
perspective.
[handouts]
- Dr. John Dawson:
Global to Regional to National: A practical approach to improving
access to the ITRF
Overview - Approaches for accessing the International Terrestrial
Reference Frame (ITRF); key elements of the Asia Pacific Reference
Frame (APREF) initiative were discussed; and illustrated Australia’s
approach to APREF to update and modernize its national datum.
[handouts]
- Dr. A.B.
Wijanarto: Semi-Dynamic Datum of Indonesia
Overview – Highlighted the realization and implementation of the new
Indonesian semi-dynamic datum and the vertical datum (geoid);
included information on the status, problems and constraints in
establishing this new datum in a relatively vast maritime
archipelago of Indonesia, with relatively dynamic geodynamic and
tectonic setting.
[handouts]
- Dr. Matt Amos:
Development of Geoid Based Vertical Datums, A New Zealand
Perspective
Overview - The development of New Zealand’s vertical datum as a case
study to show how geoid based datums can be practically developed
and implemented in an incremental and cost-effective way that meets
the needs of the end users.
[handouts]
- Mr. Kevin Kelly:
Vertical Reference Frame and GIS
Overview – Demonstrated in a GIS environment the management of
vertical reference frame data, vertical datums and transformations
between them; and vertical transformation of surveying and mapping
datasets. It also summarised two IAG services: International DEM
Service (IDEMS) as a source of vertical surface data and the
International Service for the Geoid (ISG) repository for worldwide
local and regional geoid models.
[handouts]
- Ms. Ruth Neilan:
International GNSS Service (IGS) at IAG
Overview - The latest developments of the International GNSS Service
(IGS), from Multi-GNSS to Real-Time and access to reference frame
through GNSS; the status and role of IGS from an observational
basis; the GNSS Performance Monitoring IGMA-IGS joint trial project
(with UNOOSA-ICG); timing via GNSS; and other services linked to
geodetic reference frame determination.
[handouts]
- Ms. Sharafat
Gadimova: International Committee on GNSS (ICG) at UN
Overview – the role and functions of the International Committee on
Global Navigation Satellite Systems (ICG), which included the
meeting activities of GNSS providers, other key members /
stakeholders and the four working groups.
[handouts]
- Mr. Robert Sarib:
FIG Asia Pacific Capacity Development Network
Overview – a reflection on the activities and capacity development
challenges being faced by geospatial organisations in Asia and the
Pacific; what action can be taken to combat the social, technical,
economic and environmental trends that affect not only Datum
Modernisation but also capacity development of surveyors.
[handouts]
- Prof. Manabu
Hashimoto: Crustal deformation modelling theory and examples
Overview - Theory of measurements and modelling of displacements of
the Earth’s surface with space geodetic techniques such as GNSS and
InSAR; used recent earthquakes and volcanic eruptions in Japan to
demonstrate practical application of measured displacements,
mechanical models and dislocation theory.
[handouts]
- Mr. Basara
Miyahara: Case study of Japan
Overview – Provided insight into the implementation of the GEONET
GNSS CORS network and SAR interferometry to demonstrate monitoring
and modelling of crustal deformation in Japan; used recent
earthquakes in Japan to show the deformation models that have been
developed for both consecutive crustal deformation and co-seismic
displacements.
[handouts]
- Dr. Chris Crook:
Case study of New Zealand
Overview - Using the 2016 Kaikoura Earthquake in the South Island of
New Zealand, the presentation explained how the deformation was
incorporated into the New Zealand Geodetic Datum 2000; included the
observations used, the modelling technique, and how the model is
integrated into the datum as a "patch".
[handouts]
- Mr. Satoshi
Kawamoto: GNSS analysis software “GSILIB” for utilizing
Multi-GNSS data
Overview – a review of the “GSLIB” GNSS analysis software developed
by GSI; its capability to manage / reduce the systematic biases in
multi GNSS data; the software is a fork of the open-source “RTKLIB”
software.
[handouts]
- Dr. John
LaBrecque: The promise and challenges of accurate low latency
GNSS for environmental monitoring and response.
Overview – From a GGOS perspective, examined how high rate multi-
GNSS networks can support improved coastal warning of tsunamis
induced by earthquakes, volcanic eruptions, sever weather and other
catastrophic events.
