5) Digital camera + GPS (position information):
The latitude longitude in the place is examined
with the ımage and GPS of which takes a
picture with a digital camera, it is had to
transmit, and links with the map.
6) GPS camera (position information)
links with the map based on the data with GPS
camera Which can take a picture of the
photograph.
Considering this system is used by volunteer,
1)- 4) are the method to be generally used when
above-mentioned information are offered. But
5) and 6) are not general because the equipment
such as GPS is necessary. From the viewpoint
of popularity 1)-4) is general. On the other hand
from the viewpoint of the portability of the
software, 3) is not general because the function
is largely depend on the function of mail
browser and 4) is available after the position
information in analog type in FAX is converted
to digital 4) is using the function of 1) and 2).
As the discussion above 1) -6) are put together
1) and 2) from the viewpoint of domestic usc.
So we focus on the 1) and 2) in this study from
now on.
To hold the data in common and to be thc
system domestic, the function of Web-GIS is as
follows.
- Easy GUI(Graphic User Interface)
- Sending sentence and image linked map
- Browsing sentence and image linked map
- Holding the data in common via internet
To satisfy the above-mentioned necessity. this
system is thought to be constructed with Java
applet or CGI.
Because of the problem of security for local
resources, such as file etc., Java applet has the
limitation in the accessibility from the client
machine now. So in this study CGI is used.
The information offer from the users via internet
automatically like qur necessity is established in
ESPN SporisZone3) , the sports paper of the
United States, on the internet Webgaze4),
WebNote Clip2), and AXIS NetEye 2009) etc.
There are some example that can send the
character and the image information via internet
automatically, but there is no example that can
send the character and image information linked
the map via internet as a bulletin board system.
In this study to satisfy the function of 1) and 2)
mentioned in the section 2., system was
constructed linking three parts, shuch as Web-
GIS, Information making, and Data
management part.
- Web-GIS part
- Information making part
- Data management part
Fig.3 shows the system configuration and user
interface of this system
When sentences and images are sent by using
CGI, the support screen is displayed as Fig.3 by
clicking the point where the information linked.
And data is preserved in article DB. and the
HTML file in the server when the article is
transmitted. When sentences and images are
browsed, article DB. is retrieved and the article
linked to the circumference of the clicked point
is displayed.
Fig.4 is a display of the screen when the article
is being transmitted and browsed.
4. CONCLUSION
Web-GIS which can offer the information
linked map via internet automatically without
manager's hand is proposed. This system uses
map on internet as the bulletin board. It is
thought that the image and character
information can be accurately passed on without
needing a lot of man power like the system
which was the start-up in the Nakhodka oil-spill
incident.
The near future work will be the connection to
the GIS managed ESI(Environmental Sensitivity
Index) includes the professional information for
decision support on the same Kind of disaster in
the future.
More than anything else, the unification of the
information at disaster in precondition.
