Résumé

La sophistication des technologies, en plus de la tendance Industry 4.0, a contribué à ce que la hauteur ellipsoïdale de haute précision issue du système mondial de navigation par satellite (GNSS) soit utilisée en hydrographie pour le positionnement vertical. La méthode connue sous le nom de levés référencés à l’ellipsoïde (ERS) fournit des mesures directes du fond marin à l’ellipsoïde et\ une translation précise de la référence de l’ellipsoïde par rapport au géoïde ou au zéro des cartes. Le présent article décrit une tentative de passer en revue les nations qui ont adopté la technique ERS pour la pratique des levés hydrographiques. Quelques cas d’étude sur la pratique des levés ERS sont résumés afin de déterminer les capacités de cette technique. De futures perspectives font également l’objet de discussions quant à la réalisation de la technique ERS en Malaisie, ainsi qu’au rôle des agences à l’appui de la réalisation de l’ERS. En conclusion, l’adoption de cette technique modernisera et défiera indirectement la nouvelle norme en matière de pratique hydrographique en Malaisie.

Authors should also bear the following points in mind:

  1. The title should be concise and reflect the subject matter
  2. Long passages of text should be avoided by the appropriate use of sub-titles
  3. References, which should include only publications cited, should be referenced in the text, thus (Smith, 1988), and be listed alphabetically in the Reference section conforming to the Harvard style. Some typical examples follow:

(i) References from Journals:

Certain articles, especially those dealing with historical aspects, may well have to quote unpublished, archival or 'cumbersome' material, some of which may require further explanation in note form. In such cases referred material can be cited using numbered superscripts in the text and the list of references thus replaced by a section headed 'Notes' in which explanation of the superscripts is given. Material which has been consulted but not specifically referred to in the text can be included in a separate 'Bibliography'.
