TCarta Marine, a global provider of hydrospatial products and services, will conduct a week-long coastal bathymetric mapping workshop for hydrographic surveyors in Jamaica. The workshop will be hosted by the Jamaica National Land
Scheduled for the week of February 5, 2024, at the NLA Surveys & Mapping Division headquarters in Kingston, Jamaica, the workshop will instruct participants in the use of satellite-derived bathymetry (SDB) technology with the TCarta Trident Geoprocessing Toolbox. The software-as-a-service SDB Toolbox operates within Esri ArcGIS Pro and enables users to perform their own extraction of bathymetric measurements from satellite, aerial, and UAV imagery.
“TCarta greatly appreciates Seabed 2030’s continuing commitment to expand hydrographic mapping education around the world,” said TCarta President Kyle Goodrich. “Data sets created in our workshops will be included in the Seabed 2030 global database and will also be used in diverse coastal management projects by Jamaica.”
The Seabed 2030 program was launched by The Nippon Foundation of Japan and the General Bathymetric Chart of the Oceans (GEBCO) program to inspire the complete mapping of the ocean floor by the end of the decade. A flagship program of the UN Ocean Decade, Seabed 2030 will make the data publicly available to support coastal resilience, environmental protection, and other marine applications.
TCarta first introduced Jamaican hydrographers to the SDB Toolbox in a 2022 training session. The Toolbox, which was developed by TCarta with funding from the National Science Foundation, contains a pre-processing tool to allocate calibration and validation in situ source data, two algorithm workflows to derive water depth measurements using Machine Learning and empirical regression, and a statistics estimation tool for quality assurance of derived water depth measurements.
“NLA Jamaica is eager to map the nation’s waters and contribute the data set to Seabed 2030 in time to be included in the 2024 published data,” states Diego Billings, Senior Hydrographic Surveyor for the National Land Agency, “We have already seen the benefits of producing SDB in support of NLA’s operations, and we’re looking forward to building our expertise, so that we can use these tools more flexibly.
This year’s workshop seeks to produce SDB maps of the entire coastal area of Jamaica, including the environmentally and economically important Pedro Cays
“The 2024 workshop will be led by hydrographers from TCarta’s Colorado and Jamaica offices,” said Goodrich. “We hope to hold similar SDB coastal mapping workshops in other Caribbean locations later this year and are actively seeking partnerships with hydrographic agencies in the region.”
