ABSTRACT
This research deals the Web GIS application to
prevent the damage of near shore environment
from the environmental disasters, the Nakhodka
oil. spill, occurred on Jan. 2, 1997 in Sea of
Japan.
In the Nakhodka oil-spill disaster, the
information offer started by various places to
the internet, www and Mailing-list, as the oil
moved north of Sea of Japan. However, the
information to which current event were hour by
hour updated the character based information.
So it 1s difficult to unify these information.
Moreover, considering the information
transformation method to total 770,000
volunteer gathered for oil-spill restoration, it is
important to transfer the information on the
incident timely. In such situation, the software
can offer the information on the nearshore
environmental management was needed. We
construct the Web GIS to offer the information
linked map was made on WWW(World Wide
Web) using CGI(Common Gateway Interface).
The result of this study is as follows. Near shore
region in Japan is controlled by two or more
organizations, so this system is effective for
unification of the disasters information.
Moreover, because there was the possibility that
many people in various fields took part in the
damage prevention act from the environmental
disasters like the Nakhodka oil spill disasters,
Web GIS can offer and standardize the
information for various organizations.
1. INTRODUCTION
A huge amount of information through internet
using Mailing-list and Home page in WWW
was offered as the oil-spill from Russian tanker
the Nakhodka drifted to the north of Sea of
Japan from 2 January, 1997. However there
were no way to unify wide-range distributed
information, as the result each persons had the
information in each target area in their own
brain.
Additionally many kind of information were
needed for estimating the damage on the
natural and socio-economical resources by this
kind of environmental disaster such as the
Nakhodka oil-spill.
Based on the above-mentioned background,
many people including specialists need the way
to unify these informations.
Corresponding the above-mentioned necessity
we developed the GIS on WWW in internet, and
try to unify these informations linked map for
the — Nakhodka oil-spill disasters. The
information bulletin board which was updated
and was able to be offered was made for trial
purposes, and the use was examined.
In this research, GIS as the bulletin board
system is discussed considering some lessons
from our supporting action in the Nakhodka oil-
spill disasters. And the prototype is made for
further same kind of disasters.
2. WHY WEB-GIS IN THE NAKHODKA
OIL-SPILL DISASTERS ?
Damage information was confused in the oil-
spill incident for the following reasons.
1) Confusion by wide- range distribution of oil-
spill damage:
On this oil-spill incident, the beach where oil
slicks were arrived distributed from Shimane
Prefecture to Yamagata Prefecture as Fig.l.
There were no system to open to public timely
to show the status of the distribution of the
beach and its status of such wide area. One of
the most powerful way is internet, such as
Mailing-list and Home page in WWW. The
mainly character-based information distributed
via internet were biased, because the amount of
information was large as the beach where a lot
of oil slicks were arrived, as the result the
volunteer concentrated on the beach where a lot
