  • A practical approach to the production of ENC with high density
           bathymetric content

    • Authors: A. Sanchez, V. Bosselmann-Borsos, A. Di Lieto
      Abstract: Over the last two years, the Australian Hydrographic Office (AHO) has published and maintained Electronic Navigational Charts (ENC) with greater scale and higher density bathymetric content than those derived from paper nautical charts. Land Information New Zealand (LINZ) is investigating the production of ENCs with high density bathymetric content which will likely replace the traditional berthing ENC. This article describes the approaches adopted by AHO and LINZ to produce such ENC using current IHO standards. The article describes also how AHO and LINZ engaged with stakeholders to meet the demands of large ships navigating in confined waters with small safety margins. ENCs with greater scale and high density-bathymetric content represent an opportunity for Hydrographic Offices to not only enhance safety of navigation under normal circumstances in confined waters, but also to potentially expand the range of weather and tidal conditions in which safe navigation may be conducted.

  • Methodology for quality analysis of Regional Bathymetric Surfaces

    • Authors: LCDR C. Florentino, LCDR V.B. Pimentel, A. Neto
      Abstract: There are several projects looking for a better way to represent large areas of seabed mapping using Digital Terrain Models (DTMs). Nonetheless, the selection of a DTM becomes a challenge in which the result should reflect the model with the highest quality. Thus, this paper aims to promote the development of a methodology in order to apply a set of graphical and statistical tools capable of supporting quantitative and qualitative analysis by the comparison of one surface (called LEPLAC Sul) against other DTMs available (as ETOPO1 and GEBCO_2014) and against a bathymetric control data derived from hydrographic surveys. The outcomes show that LEPLAC Sul has achieved the highest index of quality, presenting itself as an efficient reference for further national scientific researches of middle scale, like those related to oceanographic and geomorphological modeling.

  • Vertical Assessment of Lidar Bathymetry

    • Authors: M. Leger, J. Gong, I. Church
      Abstract: Validation of Airborne Light Detection And Ranging (LiDAR) Bathymetry (ALB) is necessary for the production of nautical charts to fill coastal charting gaps and to quickly and accurately measure shallow dynamic seafloors. Previous assessments concentrate on the validation of ALB data within overlapping regions of Multibeam Echo-Sounder (MBES) data. This paper presents new coverage environments to the MBES overlap validation method, and proposes an alternative method for comparison between ALB data and ENC vector information. Analysis of the validation methods favour comparisons using overlapping MBES data; however, the overlap of ALB and ENC information provides an additional assessment method with substantial overlapping regions. The ENC comparison proves to be useful at locations where MBES data is absent and in the assessment of chart adequacy.

  • Multidimensional Marine Data: The next frontier for Hydrographic Offices

    • Authors: R. Ponce
      Abstract: Hydrographic offices today exist in a world of accelerating technological change that is influencing human behavior, creating new needs and ways for exploiting data to understand our world. Hydrographic offices have traditionally been the producers of nautical information for safety of navigation. By the end of the 20th century, with the appearance of the IHO S-57 Standard, their main challenge was to evolve into a central database production system. Now, the main challenge and opportunity is to evolve from there into a true geospatial agency, developing a hydrospatial information system capable of providing products and services for multidimensional analysis and decision-making through apps and web browsers at the "speed of trust." The technology to do this is there; it is a matter of vision and desire to move toward the next frontier.
