Τhe Institute of Oceanography (IOC) has been using Geographic Information Systems (GIS) for automated mapping and geographic analysis since 1987, and organised this activity as a GIS-laboratory in 2003. Its activities focus on coastal and marine applications. 

 The development of GIS databases that store a variety of georeferenced marine information on environmental descriptors, marine biodiversity and fisheries production including Earth Observation (satellite imagery) as well as survey and monitoring data.

The development of various user-friendly analytical GIS tools for data integration and spatio-temporal analyses of biotic and abiotic parameters including software integration of several geostatistical tools.

The development of various GIS servers for the dissemination of GIS-ready marine data, GIS analytical methodology and GIS output in the form of dynamic mapping and integrated reports.

Coastal and marine data of different kinds (bathymetry, natural resources, seafloor characteristics, marine habitats etc.) are considered as spatial information layers, which are managed and combined visually and computationally (spatial correlation, analysis and calculation).
The above-mentioned data can be linked to our GIS, even if they are organized in the form of databases. All these data can be synthesized for comprehensive interpretations and forecasting of marine environmental systems. 

Planning, organization and development of geographic information database (GeoDataBase)
Generation of coastal bathymetric maps from original data
Combination of spatial and non-spatial data
Combination of raster and vector data
Marine habitats cartography
Digital Elevation Models
Thematic maps 

Specification of optimal locations for fish farms, through the analysis of bathymetry, shelter, land uses, proximity to other facilities etc.
GIS aided assistance in the development of innovative or improved infrastructure including development of new shore-based facilities such as marinas 

Analysis of erosion and shoreline changes
Monitoring the behavior of oil spillages in coastal environments 

Water balance estimation
Estimation of soil erosion and material transport at the coastal zone 

Rapid and flexible response to ad hoc “what if” type questions, by combining rapid data retrieval with analytical and modeling functions
