We held the second edition of the conference Challenges in Coastal Management with the aim of creating a space for collaboration and exchange among public administrations, experts, and local stakeholders to move toward integrated and sustainable management of the Catalan coastline. During the session, the main current challenges were analyzed, including the effects of climate change, coastal dynamics, and the need for rigorous geospatial information to support decision-making.

In this context, the Institut Cartogràfic i Geològic de Catalunya presented eight new viewers that integrate data and knowledge about the Catalan coast. These tools facilitate the consultation and analysis of key information to strengthen territorial planning and management, in coordination with the Government of Catalonia.

These viewers are:

• Beach Evolution Viewer, showing changes in shoreline position and beach width over the last 68 years.
• Coastal Geomorphology Viewer, integrating geomorphological classification of the coast, dune surface mapping, and sediment characterization.
• Storm Impact Viewer, compiling flooded areas from recent maritime storm events such as those of January 2017, Gloria (2020), and Nelson (2024).
• Coastal Hazard Viewer, identifying areas at geological risk from rockfalls and landslides along the coast.
• Catalonia Coast Comparison Viewer, enabling analysis of before-and-after orthophotos to assess storm damage.
• Permanent Flooding due to Sea-Level Rise Viewer, showing areas susceptible to flooding under different climate scenarios.
• Coastal Viewer, integrating information on coastal morphology, including bathymetry, orthophotos, and shoreline data.
• Coastal Subsidence Viewer, presenting vertical ground movements based on Sentinel-1 satellite radar data.
