With this work we tried to move a little step to find which information presented in the Electronic Navigational Charts (ENC) produced by the Italian Hydrographic Office and in the regional topographic databases could be integrated.

The backbone idea is to operate at the level of finished products, skipping any problem about the source data, collected with different rules and specifications. At this theoretical study is followed the realization, with the Ligurian Region’s cooperation, of a demonstrative ENC named “Chiavari Harbour”. The easiness with whose the aforesaid ENC’s “landing part” has been created let us suppose a quick qualitative improvement of the Italian Hydrographic Office’s portfolio of ENC.

On the other hand, from the integration of ENC’s data, the Regions could obtain a set of “marine” information at the moment largely uncared.
