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.
