All Roads in the Municipality of Attica (2023) - National Observatory of Athens

This dataset contains the complete road network of the Region of Attica, Greece, for the reference year 2023, provided in ESRI Shapefile format (roads.shp). The data, compiled and processed by the National Observatory of Athens, include polyline geometries representing road centerlines within the administrative boundaries of Attica and are suitable for use in standard GIS environments such as QGIS, ArcGIS, and Python-based geospatial workflows (e.g., GeoPandas). The coordinate reference system follows the official Greek projection standard (GGRS87 / EPSG:2100), as specified in the accompanying .prj file. The dataset supports spatial analysis tasks including infrastructure mapping, transport modeling, exposure assessment, and climate risk evaluation (e.g., wildfire, flood, or heatwave impacts on transportation infrastructure), and was used as a core infrastructure layer in regional risk assessment workflows for Attica.
