The LinePort database periodically compiles information on the characteristics of the regular short sea shipping (SSS) services connecting Spanish ports with other EU ports or ports in countries bordering the Adriatic, Baltic, Aegean, Mediterranean, Black and North Seas.

The information contained in LinePort offers a comprehensive view of the SSS services available in Spain and enables detailed analysis of the characteristics of these services in each of the ports, thereby contributing to a better understanding of the current state of SSS in Spain, its limitations and potential as an alternative/accompaniment to road transport. Twice a year, Fundación Valenciaport publishes the LinePort newsletter, a statistical document that compiles the main indicators related to the SSS services available in Spain.

The LinePort database also serves as a source for the Port Connectivity Index (Port Connectivity Index), which is jointly produced by the Port Authority of Valencia and Fundación Valenciaport, and aims to measure the comparative connectivity of Spanish ports. To that end, the  methodology used is that proposed by UNCTAD (United Nations Conference on Trade and Development) in its connectivity index called the Liner Shipping Connectivity Index (LSCI).
