The level structure is harmonized according to the standards of the INSPIRE 2007/2/EC directive of 14 March 2007 starting from the regional information level "Administrative limits". The Inspire level with linear geometry consists of a hierarchical representation of the three types of administrative area present: 4thOrder (Municipality), 3rdOrder (Province), 2ndOrder (Region). The information level has been updated with a change in the toponymy of the Municipality of Ortonovo in Luni L.R. n.5/2017 and the merger of the geometries of the municipalities of Montalto Ligure and Carpasio into the new municipality Montalto Carpasio L.R. 21/2017.
