2 Content What is the IHO S-100 product family? What is the S-102 Bathymetric Surface Product? How is the S-102 Bathymetric Surface Product produced? How can the S-102 Bathymetric Surface Product be used for improving navigational safety? What is the current status of support for the S-102 Bathymetric Surface Product?

3 IHO S-100 product family The primary goal for S-100 is to support a greater variety of hydrographic-related digital data sources, products, and customers. Will enable wider use and transfer of hydrographic data than S-57 Is aligned with a contemporary standard (ISO 19100) Use of imagery and gridded data, enhanced metadata specifications, unlimited encoding formats and a more flexible maintenance regime.

4 IHO S-100 product family S-101 Electronic Navigational Chart (ENC) S-102 Bathymetric Surface S-103 Sub-surface Navigation S-104 Tidal Information for Surface Navigation S-111 Surface Currents S-112 Dynamic Water Level Data S-121 Maritime Limits and Boundaries S-122 Marine Protected Areas S-123 Radio Services S-124 Navigational Warnings S-125 Navigational Services S-126 Physical Environment S-127 Traffic Management S-128 Catalogues of Nautical Products

5 S-102 Bathymetric Surface Product Part of the S-100 product family A product specification for bathymetric surface data which may be used alone or as an auxiliary layer of data with an ENC. A navigation surface coverage including both depth and uncertainty. Optional tracking list of the depth changes that have been manually replaced by the hydrographer to ensure safety of navigation. Must be certified by a hydrographer using a digital signature.

6 S-102 Bathymetric Surface Product Product: High definition gridded bathymetry. Purpose: To support safe navigation as an auxiliary aid. Use: Navigation and planning: Safe depth, under keel clearance, anchorage areas, situational awareness. Innovative: Seamless calculation of depth contours Available water column by integrating tidal data. Calculation of dynamic under keel clearance

7 Production of S-102 High quality survey data necessary Same reference level as used in ENCs

8 Production of S-102 A resolution is generated in accordance with the source data. The resolution will vary with depth, type of echo sounder used and the variation in bathymetri. An algorithm is used to calculate the mean value of each cell A cell without source data will be shown as void.

9 Production of S-102 The grid creates a model of the bathymetri. A «tracking list» gives the option to overrule data in the model with manually selected depth values. Safety of Navigation: The Mean Value in the cell can be less than the shallowest value. Mean Value replaced with shallowest value.

10 Production of S-102 Statistics regarding the data set is generated: Min and max values, standard deviation. Standard Deviation: The average distance the individual depth value deviate from the calculated cell value. S-102 can be used in conjunction with other data: (ENC).
