BATHMETRY ISSUE

[TUOAA21]

Researchers and inventors in Yemen and other less developed countries lack access to modern and accurate marine data and information, including high-resolution bathymetry (1-39 meters). How can researchers in Yemen contribute to environmental protection when developed countries, which benefit from Yemen's marine environment, refuse to provide support, access data and information, and share it—rights guaranteed by international maritime conferences?

Globally you have the GEBCO bathymetry datasets (available in the Living Atlas) that are a part of the Seabed 2030 Program.  https://seabed2030.org/ - So the mechanisms for bathymetry holdings from Yemen to be contributed to the larger and greater good are in place.  Is there a GIS related question or an issue with a data layer that you have identified?

Yes, I used GECOB and only downloaded BATHYMETRY height, resulting in 180 meters.  Actually, GIS is still my excellent and favorite device. but lastly I found challenges in using GIS tools to study and analyze, creating a contour on the positive side, to create a BATH, TIN, and SEAFLOOR. I wish to find GIS extension tools for marine processes, as well as hope to find access and connection to world marine centers.

For assistance on GIS tools for marine processes please reach out to @MeredithPayne1 (and see https://mediaspace.esri.com/channel/ArcGIS+Bathymetry/279233602). For other world marine centers, the IODE that I mentioned is certainly one, but the Seabed 2030 regional data centers are also good places to connect to, https://seabed2030.org/about/, and Steve Hall <partnerships@seabed2030.org> can assist you.

You might also look to EMODnet - Data products - EMODnet Bathymetry and specifically their tiled world bathymetry - EMODnet Bathymetry WMTS

To add to Keith's helpful response, I would also suggest reaching out to the UNESCO International Oceanographic Data and Information Exchange https://iode.org/about/who-we-are/ , info@iode.org, to help you navigate access to the data and information that you seek, as well as contributing your expertise in environmental protection. Another initiative that may be of interest is the Ocean Discovery League's Low-Cost and Accessible Technology project at https://www.oceandiscoveryleague.org/low-cost-accessible-technology

UNESCO and IMO are working together, but they offer high-resolution bath 180 meters products in 2025, which is better than 2022. that was 450 meters.
