This deliverable presents the list of the thematic underwater services of WP2 released by NEANIAS project in its third release cycle, due in M30 of the project.

This deliverable D2.7 “Underwater Thematic Services Release #3” is produced in the context of WP2 “Underwater Research Services” of the NEANIAS project. Services released are further detailed in deliverable D2.8 [2] , which is currently being prepared.

The deliverable refers to services released under the group of thematic services for the Underwater Community, namely:

• U1 - Bathymetry mapping from acoustic data, named “UW-BAT”, provides a large number of MB-System tools to post-process vendor specific raw data. Its approach is to create digital terrain models (DTM) and maps from multibeam echosounder (MBES) raw data.
• U2 - Seafloor mosaicking from optical data, named “UW-MOS”, provides an operational solution for large area representation of the seafloor addressing also visibility limitations from the underwater medium.
• U3 - Seabed classification from multispectral, multibeam data, named “UW-MAP”, delivers a user-friendly cloud-based solution integrating cutting-edge machine learning frameworks for mapping several seabed classes, validated for archeological, geo-hazards, energy, and other applications.
