DESCRIPTION:Due to the compounding impacts of climate change and human acti
 vities\, the frequency and severity of hazards and natural disasters are o
 n the rise\, exerting significant impacts on the environment\, economy\, a
 nd human lives. Responding to this shifting landscape\, numerous instituti
 ons and political structures are redirecting their focus from emergency re
 sponse to proactive disaster risk reduction and planning. Notably\, the pu
 blic Authority has sponsored the project titled "Creation of an Integrated
  Observatory System for Preventing and Managing the Risk of Coastal Erosio
 n due to the Impact of Climate Change through the Utilization of Earth Obs
 ervation Data". This initiative employs Earth Observation\, combined with 
 in-situ data\, advanced algorithms\, and models\, to develop comprehensive
  knowledge on hazard exposure and vulnerability. \nThe applied methodology
  encompasses three thematic phases: Phase A includes the creation of algor
 ithms and tools for calculating necessary indicators\, Phase B involves th
 e design of the web GIS application hosting the observatory\, its services
 \, and derived datasets\, and Phase C entails evaluating the current state
  and proposing alternatives for risk management. \nSpatial databases were 
 continually reassessed throughout the project\, hosting digital products c
 reated by specialized Python scripts that process optical images from Sent
 inel-2 satellites\, Sentinel-1 SAR acquisitions\, and in-situ measurements
 . These data sources contribute to generating timeseries of multiple indic
 ators related to coastline alterations. The extensive monitoring database 
 serves not only to establish correlations between derived indicators and h
 uman activity but also to calculate 50- and 100-year simulation indicators
  for coastal vulnerability under tidal wave pressure. Additionally\, a too
 l for determining passive flood mapping in different sea level rise scenar
 ios is developed using the bathtub approach. \nAll this information is sea
 mlessly integrated into a web GIS application\, named "Observatory System 
 for Coastal Erosion." The application utilizes the Angular web application
  framework while the Leaflet library enhances interactive mapping\, provid
 ing a user-friendly interface. Navigation features include zoom in/out too
 ls\, selection/identification tools\, and an address bar. Users can search
  data using descriptive or spatial parameters\, applying filters\, with re
 sults displayed in a table for export in .csv or .shp formats.\nThis appli
 cation ensures interactivity\, interoperability\, and information exchange
 \, supporting decision-making and evaluating alternative coastal zone deve
 lopment strategies. Fully aligned with national Integrated Coastal Zone Ma
 nagement (ICZM) principles\, the observatory has been in use by the Depart
 ment of Environment and Industry\, Energy & Natural Resources of the Regio
 n of Central Macedonia since 2021. Networking activities have already comm
 enced among stakeholders and public authorities\, addressing erosion issue
 s highlighted by the project's results and exploring alternative\, sustain
 able prevention measures.
