CTU Prague & Jupem Cooperation

In a recent journal published by Czech Technical University, Prague (CTU) - Geoinformatic FCE CTU (link) there is a paper on calibration of digital level. This paper reported about the cooperation of CTU and Jupem Malaysia i.e., Geodesy Section of Jupem on automatic calibration of digital levels for Jupem. The project started in 2009 and the calibration system was set-up at Jupem which took nine days for the installation to be completed.

Height Datum Unification - PhD in Geodesy Estonia (2013)

Recently I was made available to access a PhD work completed at one university in Estonia  in 2013. The thesis entitled "Precise hydrodynamic levelling using pressure gauges with application to improvement of the Estonian national levelling network" submitted by Dr Aive Liibusk to Estonian University Life Sciences, Tartu. The examining committee was consists of Prof Markku Poutanen from Finnish Geodetic Institute and the work was join supervised by Prof Artu Ellmann (of Tallinn University of Technology) and Assoc Prof Harli Jurgenson (of Estonian University of Life Sciences).

The research was part of efforts contributed in modernizing and unification of height datum in Estonia. The main contribution was the implementation of a special technique of hydrodynamic heighting connecting levelling from mainland to distant island of tens of kilometer away using pressure gauges.

Geoid Talk - Series 3

Another series of talk on geoid computation was given this morning at Girg meeting room. It was attended by a number of grad students and I thank them for their patient in listening. Actually the talk was arranged ad-hoc and it is more of sort of repeating what was discussed in previous meetings.

Among the main points highlighted in the talk were the three input data required for geoid computation - terrestrial data, ggm contribution and DEM. Emphasis was also given on the development of current GGM and the role it plays in geoid computation. The concept and availability of various form of Stokes modification formulae was also highlighted. In the end a review of geoid development and revision in several countries around the World was mentioned.

Prof Hans-George Wenzel (1945-1999)

When talking about the stochastic approach of modification of Stokes for geoid computation two names always been quoted - Sjoberg and Wenzel. Prof Sjoberg is famous with his formulation described particularly in three journal papers (Sjoberg 1984, 1991 and 2003) while Wenzel has two both published in 1980's (Wenzel 1982, 1983). As mentioned in previous post Wenzel's work on stokes modification can only be found in these two papers. It seemed no follow-up and no taker continuing his work. This is understandable as a results of his demise in 1999 at the age of 54.
Wenzel in memoriam written by Torge in IAG Newsletter March 2000 can be read here.

Wenzel was born in 1945 and he studied geodesy at TU Hannover in 1968-1972. He then entered Institute of Theoretical Geodesy U of Hannover and he received the Doktor-Ingenieur degree with a thesis on the accuracy of gravimetric earth tides observations (1976), and his Dr.-Ing. habil. thesis dealt with high resolution spherical harmonic models for the gravitational potential of the earth (1985).

Wenzel two monumental papers on stochastic stokes modification were;

Wenzel H.G. (1982): Geoid computation by least-squares spectral combination using integration kernels. In Proceedings of IAG General Meeting, Tokyo. pp: 438-453
Weber, G & Wenzel H.G. (1983) Error covariance functions of sea gravity data and implication for geoid determination. Paper presented to IAG General Assembly, Tokyo. Marine Geodesy 7: 199-226

Another major publication of importance to geoid is;

Wenzel (1998) Ultra-high degree geopotential models GPM98A, B, and C to degree 1800. In Proc of the joint meeting of the International Gravity Commission and International Geoid Commission, Trieste Italy.

Stochastic Stokes Modification - Sjoberg & Wenzel Works

In geoid computation method there were two types of Stokes modification (SM) been developed - the deterministic and the stochastic approach. Examples of the former include Molodenski et. al (1962), Wong & Gore (1969), Meissl (1971) , and Vanicek & Kleusberg (1987). As for the stochastic approach  there were only two researchers have ever ventured into it - Sjoberg (1984, 1991 and 2003) and Wenzel (1981, 1983). The main difference between the deterministic and stochastic Stokes modification approach is that in the former minimizing truncation error is the only aim while the latter concerns not only the truncation error but in addition errors in terrestrial gravity data and GGM-derived gravity anomalies were taken into account as well.

In comparing the two stochastic approaches  i.e., Sjoberg and Wenzel works, the former was further actively developed and eventually resulted with a complete geoid computation package known as KTH Geolab. Wenzel work was not pursued further other than the two papers published (Wenzel 1981, 1983). Professor Wenzel (b.1948) died in 1999 at age of 54 and that put sort of a full stop to his idea of stochastic approach of Stokes modification.

Bulgaria Geoid - 2001 and 2004

Bulgaria geoid has been worked by Assoc Prof Elena Peneva of Geodesy Dept, U of Architecture, Civil Engineering and Geodesy, Sofia. Her work was submitted as a doctoral dissertation entitled "Gravimetric Geoid Determination for the Territory of Bulgaria" (in Bulgarian) at the same department in 2001. It was later published as a journal paper "A preliminary gravimetric geoid model for the territory of Bulgaria" in AVN 10/2004. The Bulgaria geoid was computed by remove restore technique employing FFT method using Gravsoft geoid package. She later evaluated this geoid with gps-levelling data and the results were then published in 2006.

Geoid Talk - Series 1

Today I gave a talk entitled “Geoid-related Intro” to a small audience of GIRG members. The talk lasted about two hours. The talk deals mainly on basic definition of geoid by describing it as another example of Earth nature creation. The early development of geoid computation using Stokes formula was discussed next. The limitation of Stokes geoid was highlighted which then led to the introduction of Stokes modification concept. The talk ended by describing further improvement to Stokes modification technique developed by Prof Sjoberg of KTH Sweden. The major characteristics of least squares modification of Stokes used in KTH approach was described towards the end of the talk.

Croatia Geoid - HRG2009 (2014)

Croatia newest high resolution geoid model is HRG2009 developed by Tomislav Basic & Olga Bjelotomic, both from Faculty of Geodesy, Zagreb University. A publication describing development of HRG2009 can be found in book: Gravity, Geoid and Height Systems, Proceedings of the IAG Symposium GGHS2012, October 9–12, 2012, Venice, Italy.

The paper can be download here - IAG Vol 141 dan IAG Venice.

HRG2009 is a gravimetric geoid model for Croatia. It covers the entire territory of Croatia ranging between 42° and 46.6° in latitude, and between 13.0° and 19.5° in longitude, with a grid resolution of 30"x45". It is referred to the GRS80 ellipsoid in the Croatian HTRS96 datum. Data from terrestrial gravimetry and from satellite altimetry for the area of the Adriatic Sea were used. The model was computed by least-squares collocation in the framework of a remove-restore procedure. In particular the long-wavelenght part is derived from the EGM2008 global geopotential model, while the short-wavelenght part is mainly taken from a digital terrain model of 4"x5" obtained from 3"x3" SRTM data. The accuracy assessment of the HRG2009 model was performed by comparing it with 59 GNSS/levelling control stations, which were not used in calculations. The resulting differences have a standard deviation of 3.5 cm over the whole computation area, thus significantly improving the standard deviation of 11.4 cm obtained with the previous national geoid model HRG2000.

Tahiti Geoid - Cheinway Hwang (2015)

Profesor Cheinway Hwang mengetuai Space Geodesy Laboratory (SGL) di National Chiao Tung University (NCTU) Taiwan. SGL adalah di bawah Department of Civil Engineering NCTU. Cheinway merupakan pakar dalam geodesi fizikal dan banyak terlibat dalam penyelidikan mengenai geoid dan oseanografi. Beliau memperolehi PhD dari OSU pada tahun 1991. Antara sumbangan besar beliau kepada Taiwan ialah merancang dan melaksana projek airborne gravity dan seterusnya menghasilkan geoid bagi Taiwan sekitar tahun 2006 hingga 2009.

Kepakaran SGL dalam melaksana pengukuran airborne gravity dan hitungan geoid telah membolehkan mereka menjalankan projek yang sama ke negara lain. Terkini Cheinway dan kumpulan geodesis Taiwan telah menghasilkan geoid untuk Kepulauan Tahiti. Projek ini juga melibatkan airborne gravity yang dilaksana sendiri menggunakan kepakaran Taiwan.
