Since 2010, Esri and NOAA, under the auspices of the International Hydrographic Organization (IHO) and the S-100 WG (formerly TSMAD – Transfer Standard Maintenance and Application Development Working Group), have jointly funded the development of the S-57 to S-101 Converter. The converter is a critical component of the S-100 Test Bed project and its roadmap for the operational release of S-101.

A Workshop on Bathymetric Data Processing was held at the German Hydrographic Office (BSH) in Hamburg from April 9th trough 11th 2019.

It was attended by 11 national hydrographic offices from the Baltic and North Sea regions, one regional center for ENCs (RENC), the Chair of the IHO ENC Working Group, and 4 industries.

The purpose was to discuss the increasing requirement to produce and provide high density bathymetry for nautical charts and other purposes, identify common issues and propose common solutions. During these two and a half days, Esri’s Maritime experts supported by Esri Germany presented the latest automated workflows for contouring and sounding selection in ArcGIS Pro, moderated and discussed common pain points with participants and came up with some conclusions at the end that will be reported to the International Hydrographic Organization as recommendations for all member states consideration.

Esri, the global leader in location intelligence, announced on April 5th 2019, that it has contracted with the Lithuanian Transport Safety Administration (LTSA), Hydrography Division. LTSA will partner with Esri; local distributor Hnit-Baltic; and Quality Positioning Services (QPS), a Saab subsidiary, to implement a new seabed database and nautical cartography system.


ArcGIS for Maritime: Charting, Esri’s marine products solution, is used by companies and government agencies around the world to create and manage maritime information for navigation products and a wide variety of GIS purposes, including coastal planning, seabed analysis, and data sharing.

The US Hydro was a four day event, from March 18th through 21st 2019.

Organized every two years, alternating with Canadian Hydro by the Hydrographic Society of America (THSOA), it was in Biloxi, Mississippi this year.

It brought together people, government organizations, academia and industry connected with the hydrographic domain. The purpose was to share professional knowledge and the latest technology developments applied to hydrographic sciences.

THSOA also had its general meeting during the conference, bringing representatives of all the national chapters, and Latin America, that ArcGIS for Maritime's Rafael Ponce chairs, to present an annual report and discuss common issues, membership and work plans.

Esri had a booth and a half a day workshop on Monday, which was hosted by our ArcGIS for Maritime subject matter experts: Randall Billy, Caitlyn Raines, Lee Brinton, Guy Noll and Rafael Ponce. The special guest attending was Clark Lawlor from Esri Canada.

During the week, there were meetings with leaders and representatives from some national HOs such as NOAA, NGA, USACE, Canadian Hydrographic Service, as well as academia such as University of Southern Mississippi (USM) and University of New Hampshire (UNH), to discuss their different needs and implementation of the ArcGIS platform in their organizations.

Hydrography students were also some of the interested visitors!
