and IHO Workshop,
Malahide, Dublin. Ireland
21st to 23rd March 2007
Land and Marine Information Integration
Background and Purpose of the Workshop
With climate change, rising sea levels pressing harder year on
year and the need to manage our resources more carefully in this
dynamic environment, the inability to join up land and marine base
information is an increasing problem in many countries. The absence
a seamless spatial information framework prevents the execution
of standard practice of locating and referencing spatial information
across the land-marine interface where so much pressure and development
is taking place.
This also inhibits the use and sharing of information by those
organisations in the front line of stewardship, it leads to data
duplication often resulting in a proliferation of discrete data
collection projects, and these can be substantial investments. Often
here the data is generally captured once (for a specific purpose)
and used only once.
For the European Commission and Member States of the EU this topic
is very relevant to INSPIRE, as part of cross theme data consistency
(coordinate systems, several data themes, data matching and semantics).
It is applicable to a number of themes in Annex I-III across the
land and marine environment such as the Elevation, Hydrography/Hydrology,
Transport networks, Protected sides, Buildings, Land use, Oceanographic
geographical features, Utility information, Addresses, Geology,
etc. Specific themes that might also need to be referenced are the:
environmental monitoring facilities, area management, natural risk
zones, sea regions, bio-geographical regions, habitats and biotopes,
species distribution & energy resources etc.
At the organisational level a further complication arises from
the fact that in the marine environment, the task of surveying and
“mapping” is normally undertaken by a hydrographic organization
which is usually separate from the land mapping authority. The hydrographic
function to provide charts, nautical publications and update services
is primarily for the safety of navigation. The International Hydrographic
Organisation (IHO) has however recognised the importance of establishing
a marine spatial data infrastructure and in November 2005, the German
hydrographic office hosted an SDI seminar in Rostock Germany. The
focus of the seminar was “The Role of Hydrographic Services with
Regard to Geospatial Data and Planning Infrastructure”. This was
followed by a workshop in February 2007 (in conjunction with GeoCuba,
Havana), to determine the need for IHO members to pursue the concept
of a Marine Spatial Data Infrastructure (Marine – SDI). The workshop
concluded with the following resolution:
- IHB to communicate with IOC to cooperate on the development
of the spatial data standard S-100, with a view to facilitate
marine/hydrographic data exchange.
- IHB to advertise and promulgate S-100 to the wider spatial
data user community, including the mapping organizations.
- The workshop supported reinforcing the need for IHO to move
forward on developing a strategy for designing and implementing
Marine SDI, including an assessment of associated benefit to society.
- IHO Regional Hydrographic Commissions to have "Progress on
Marine SDI Development and Land-Sea Data Integration" as a standing
agenda of their meetings.
- IHB to establish on the IHO website a special page dedicated
to Marine SDI developments, including the outcomes of regional
workshops on the matter.
These recommendations and the outcomes of the Malahide workshop
are to be used as inputs to the IHO General Assembly in Monaco in
The aims of the workshop were to determine and document the state
of the art and progress at national level and across Europe in integrating
maintained national land and marine databases, specifically by exploring:
- the drivers for integration at national level
- current status
- issues that require attention
- examples of best practice
- future steps
notice of the workshop was issued in late 2006 and was updated
at intervals as the programme developed.
The workshop was sponsored by EuroSDR on behalf of the European
national mapping agencies and the International Hydrographic Organization
(IHO) for the hydrographic offices. The workshop was also supported
by the Joint Research Centre of the European Commission and by EuroGeographics.
Ordnance Survey Ireland sponsored the workshop dinner and the Society
of Chartered Surveyors of Ireland sponsored the audio-visual arrangements
at the workshop.
