CoastGIS'99: geomatics and coastal environment
The will to protect the environment means that greater attention is paid
to elements which belong directly to the sea: sea mammals, fragile
habitats. The cultural heritage of the sea also tends to be the subject
of conservation measures. Protecting the quality of the environment and
safeguarding the health status of the consumers often involve a geographical element.
Since the sea is not usually dedicated to one user, many different uses
may succeed one another or may occur simultaneously. The activity areas
may shift. The rules and regulations overlap, or change are adapted
continuously.
Recent development
In the last few years, a whole array of planning measures, which incorporate (or not) a statutory aspect, have been gradually set up after
consultation with the various parties in order to attempt to settle
conflicts and ensure sustainable management. Although this undertaking has only enjoyed moderate success up to now, the local authorities have put forward more explicit claims in their attempt to play
a more active role in finding a sense of balance between the various
activities and to define the boundaries which fall within their scope as
regards the sea. However their policing responsibility only covers a
restricted zone.
Transcription of georeferenced data
State of the art
“Communal” boundaries are the subject of a systematic transcription
on all terrestrial maps. The information represented on the topographic
maps have been digitized to constitute the numeric georeferenced databases of the National Geographic Institute (IGN). These data are of
general use and can be included as references to build other bases. The
protected environmental areas are digitized according to the IGN reference, even though these areas extend as far as the sea. A national network of fresh water data and a specifîc base have been created according to the IGN reference. In addition, water catchment boundaries and
regulatory zonings have been included. High scale data concerning
property register data are currentiy being digitized. All these data are
standardised and will be available on a national levei, the agencies in
charge of their release have been named and the access procedures have
been decided.
Concerning the sea, the main available information can be found on the
marine charts. In this field, international coordination and a high level
of standardisation exist. These charts are drawn and managed by the
Hydrographic Division of the French Navy (Shom). All information
concerning navigational safety, on the surface or on the sea-bed, are
shown. Elements included on marine charts have been used to formalize
international law and some charted boundary lines are used in preference to the textual version. All the international boundaries have not
