Visit of Prof Chen Yongqi (1995)


Another big name who has visited Faculty of Surveying and Cimes in particular is Prof Chen Yongqi. Dr Chen is from LSGI Dept Hong Kong Polytechnic University. I have the opportunity working together with Dr Chen at UNB as a team on deformation analysis under the directive of Dr Chrzanowski. At the time of Dr Chen visit he was Chairman of Commission 6 of FIG (the commission on Engineering Survey).

Dr Chen is the author of a famous technical report on deformation analysis "The Generalized Approach on analysis of deformation". It was published as Technical Report 94 of UNB Dept of SE publication way back in 1983.

Visit of Prof Adam Chrzanowski of UNB (1995)


One special event that I have involved with in 1995 was the visit of Dr Adam Chrzanowski to Faculty of Surveying UTM. Dr Adam is from UNB Canada and he is the world renown academic in geodetic deformation analysis. Dr Adam is my mentor during my days at UNB and I was personally arranged this special visit by him to establish contact between our small research group Cimes (representing Dept of Engineering Survey or UKK) and UNB. Since Dr Adam at that time is the Chairman of FIG working group in analysis of deformation therefore his visit really has a very significant meaning to Cimes research work in the same discipline.

LevaIlois Medal winner - Prof Baarda (IAG Boulder 1995)


Levallois medal was established by IAG in 1979, to honour the former Secretary General and his outstanding contributions to IAG. The award is made in recognition of distinguished service to the Association, and/or to the science of geodesy in general. During IAG 1995 the Levallois medal was awarded to Professor Willem Baarda. Prof. Baarda worked for several decades at the Technical University at Delft, Netherlands, and the results of his research strongly influenced geodesy.
The contributions of Baarda were;

- he was the first to develop a systematic framework of statistical quality control, including the famous "data snooping".
- he also firstly introduced criterion matrices for testing a network precision, and invented the reliability concept, now at widespread use.
- finally, the invention of the S-transformations, nowadays employed at "free network" adjustments.
Some of Prof. Baarda's publications from the 1960's and 1970's belong to the fundamental literature in geodesy. Most recently (in 1995) a new basic publication from Prof. Baarda was highlighted, related to the coupling and interaction between geometric and physical geodesy.
Between 1979 and 1991, the award was given to Charles Whitten (USA), Rudolf Sigl (Germany), Arne Bjerhammar (Sweden), and Paul Melchior (Belgium).

IAG 1995 Boulder - Important Activities & Development


The following activities represent among major developments contributed by IAG between 1991-1995;
  1. The International Earth Rotation Service (IERS) continued to work with great success as a joint enterprise of IUGG and IAU since 1988. Providing the basic reference frames by employing advanced space methods.
  2. The development of regional reference networks - examples of this type of work are the European Reference Frame now extended to Eastern Europe, and the SIRGAS project in South America, and the International GPS Service for Geodynamics started routine work on January 1, 1994, and proved to be extremely successful.
  3. the International Geoid Service, located at Milano, is operational since 1992, and provides effective support to individuals and agencies, involved in geoid determination.
  4. one outcome of active GALOS group, chaired by Petr Vanicek, which is the establishment of an IHO (International Hydrographie Organization) / IAG Advisory Board on Hydrographic and Geodetic Aspects of the UN Convention on the Law of the Sea.
  5. IAG activities outside Europe & USA started spreading - as examples the Symposium on Geodesy in Latin America in Vienna 1991, and the forthcoming Symposium on South East Asia, to be held here in Boulder, as well as Symposia or Workshops in Maracaibo, Bali, Lagos and Nairobi held between 1992 and 1994.

Projek Kajian Kegagalan Struktur Pemecah Ombak (1995)


Tahun 1995 merupakan period aktif penglibatan dalam projek perundingan. Sebagai tambahan kepada tiga projek yang disebut sebelum ini ada satu lagi projek perundingan yang telah disertai dan ianya di luar Johor. Kerja yang dimaksudkan ialah Projek Kajian Kegagalan Struktur Pemecah Ombak di Terminal Eksport Gas Tanjung Sulong Kemaman.

Kerja ini melibatkan ukur pengawasan (atau monitoring survey) dibuat oleh pelajar  ukur tanah yang ketika itu sedang dalam latihan industri. Pada ketika itu (i.e., tahun 1995) latihan industri pelajar adalah dikelola sendiri oleh Fakulti Ukur di bawah Unit Perundingan Ukur dan Latihan (UPUL). Penglibatan saya dalam kerja ini bukanlah sebagai staf UPUL tetapi diminta menyertainya sebagai penganalisa dalam kerja yang melibatkan analisa deformasi.

Pensyarah UPUL yang menjadi penyelia kerja sebenar projek ini ialah En Matharudin Yusoff dan En Radin Jayakasuma. Sepanjang tempoh kerja tersebut semua staf dan pelajar terlibat menyewa rumah di sebuah taman perumahan di kawasan Kemaman.

Projek Ukur Butiran Tapak Pelancungan (1995)


Projek perundingan kedua yang disertai pada tahun 1995 ialah projek ukur butiran (details survey) untuk satu tapak pelancungan di Mukim Sedili Besar, Kota Tinggi. Disamping memenuhi tuntutan pihak klien projek ini juga mendedahkan staf yang terlibat dengan rutin kerja ukur butiran secara automasi. Pada ketika itu konsep automation survey masih baru dan belum banyak dipraktis kerana ia memerlukan peralatan dan software yang bersesuaian. Dalam projek ini perisian ukur TRPS telah digunakan.

Klien projek perundingan ini seorang ahli perniagaan yang merancang untuk memajukan tapak yang diukur dengan mendirikan chalet untuk pelancung menginap.

Tak ada pula yang bawa kamera maka tidak ada foto yang dirakam.

Projek Ukur Aras Jitu Jambatan Pulau Pinang (1995)


Period 1994 dan tahun-tahun berikutnya juga diisi dengan beberapa projek perundingan.  Salah satu kerja perundingan yang dibuat ialah Projek Ukur Aras Jitu Jambatan Pulau Pinang. Klien projek ini ialah Syarikat Juruukur Ayob Saud (SAS) yang berpengkalan di Pulau Pinang. SAS pula memperolehi kerja tersebut dari syarikat konsesi yang  bertanggungjawab mengendalikan Jambatan Pulau Pinang. Di peringkat Fakulti Ukur projek perundingan ini diketuai oleh Encik Shaharudin Mohd Said.

Projek Ukur Aras Jitu berjalan agak lama meliputi tempoh sebulan mungkin(?).  Sudah lupa tempoh yang betulnya kerana ia dilaksana lebih dua puluh tahun lalu. Yang pastinya staf terlibat telah bergilir-gilir duduk di sana seminggu (kemudian diganti pula staf lain) dengan menyewa sebuah rumah di Kg Seronok, Bayan Lepas.

Sebagai mana amalan biasa ukur aras jitu hanya boleh dibuat pada awal pagi hinggalah jam 10 atau 11 pagi mengelak cuaca panas. Sekiranya perlu ia disambung pula sebelah petang pukul 4 hingga 6 atau 7. Waktu kerja juga bergantung pada keadaan pasang surut air laut. Waktu air surut susah kerjanya kerana paras bot terlalu rendah dan perlu guna tangga untuk memanjat sampai ke tiang jambatan. Ini suatu yang cuba dielakkan kerana bahaya.
