"Costa Concordia: Rock Not Charted or Erroneous Navigation?
from Hyrdo International - 16/01/2012
On the evening of Friday, 13th January 2012, the cruise liner Costa Concordia grounded near the Italian island of Giglio after hitting an underwater rock. This tragic event has raised various questions, including whether the ship was navigating too close to the shore and whether the rock was properly charted.
The vessel was in touristic navigation, passing by the picturesque island Giglio. This is a manoeuvre which is done from time to time. However, this time, the vessel approached the coast very close to the dangerous Le Scole reef area. The minimum distance to the shore usually is a couple of miles. Even inhabitants of the island remarked that the cruiseship appeared to be closer than usual.
According to several sources, the captain of the Costa Concordia has stated that the rock the ship hit was not charted. The vessel has a draught of 8.2m and was sailing approximately 300m out from the shore and the rocks. The area is said to be well-charted, and the place is used for diving and sailing which makes it well-known.
It is not completely clear where the Costa Concordia hit the rock. According to AIS sources, the vessel may have tried to navigate between two rocks with a depth of 10.3m.
After the incident, the vessel navigated close to the shore, towards the harbour. When turning, the vessel listed to one side, which was critical in view of the shallow waters.
The position is not yet stable: on Monday, 16th January 2012, the Costa Concordia moved 9cm downwards. If this continues, due by bad weather for example, she may even slide from the rock, potentially to a depth of 100m.

According to Lloyd's List on BBC, the Costa Concordia followed a comparable route in August 2011. No rocks are shown on the UK Hydrographic Office's charts, but the UKHO has stated that this could be due to the small scale of its charts, whereas Italian charts are available on a much larger scale.
The Italian Hydrographic Office is working on a detailed study regarding the charting and survey situation of the location.
A potential source of a new 'liability for GI/map/chart data' case building up? We haven't had many in the past fw years.
But also have a look at this 14 min video tracking the last minutes of the Concordia's approach to the shore - and the basic navigation mistakes that seem to have been made - as well as the fact that the rocks that the vessel first hit are clearly visible on the charts! No escaping the ever present AIS (Automatic Identification System) data.
All the best

About the LAPSI project

LAPSI is a project in the FP7 program of the European Union.
Legal Aspects of the Public Sector Information and Re-use.
Timespan: 30 months. Participants: 20 institutions and organistions. Coordinator: University of Torino.
Kick-off Meeting: Torino, 26-28 March, 2010

Role of HUNAGI in the LAPSI Project

HUNAGI contribution is related mainly to the Geographic Information which are produced, maintained and used in land management, including surveying, mapping, cadastre and land registration, remote sensing and serviced by relevant spatial data infrastructures. From a national economic point of view, the uniform land registration system operating in Hungary is one of the most important databases of the country. This system allows to obtain over the time updated legal and geometric data, as well as other information (e.g. on ownership, land uses, mortgages, etc.). The cadastral maps integrated into the uniform land registration system show spatial relations and references of rights, facts and other information appearing on the property sheets, serving as a basis of engineering planning for the national economy. The national spatial data infrastructure can be built on this uniform, authorized and public land registration system, in small partial modules, following the EU INSPIRE Directive. HUNAGI will participate to all Working Groups and actively take part to Working Groups 01, 03 and 04. It also makes its facilities available to host one of the thematic network seminars or conferences.
