Information system is
crucial to disaster management both for disaster prediction and relief.
Specially, in the information era, building a disaster information system
adopted geospatial technology for disaster management is practiced in many
countries. Geospatial technology is uniquely suited to collect information of
disaster prevention, assess the impact and help remediate damages.
In recent years, spatial
information technology has been applied in many organizations for disaster
management in
Information sharing is important
for administration, while it is difficult for across governmental organization
coordination in the current stage1. New technology is key important to this
respect. A web based GIS system with multipurpose applications is designed for
this purpose. The system concept design includes a GIS. SuperMap, a creative and
powerful GIS package is to be used as a core technology for building the
system. The system will provide GIS functionalities and spatial analysis. And
the system will have open protocol that can be integrated with any other systems
in different subjects.
SuperMap, developed by a
The functionalities of
the system for spatial data management, such basic maps, remotely sensed
imageries and dynamic GPS data will be developed. The system is of an open technology
structure and can be easily integrated with other systems and can play
important role in information collection, disaster response, disaster
evaluation and relief.
Following
are the main contents of the basic database:
l
Basic
maps, map scale at 1:1,000,000, and partly 1:50,000;
l
Remotely
sensed imageries, such TM, SPOT and partly Quick Bird and IKONOS;
l
Thematic
maps such digital terrain model data, geology maps, flooding maps and disaster
prevention data;
l
Road
system and transportation;
l
Hospitals
and medical facilities;
l
Urban
and town distributions and facilities;
l
Population
density data;
l
Social
and economic data and etc.
It is a web based system
and it can be accessed by different originations. And those organizations can
base on the system to develop their own applications. Because the system is an open
structure and other system and applications can also easily embedded with in
the system. For instance, in flooding disaster prevention, remote sensing
technologies, such as
