Case Study(Earthquake in Wenchuan)
Wenchuan Earthquake, 2008, M8.0
Floods in South China, 2010
Mudslide in Zhouqu 2010
Yushu Earthquake, 2010, M7.1
n Frequent and varied types of natural hazards in China
… Strengthen development on key technologies
about disaster prevention and mitigation … speed up
high-tech achievements transformation and
integration of RS, GIS, GPS, network communication
technology, as well as disaster prevention and
mitigation , establishment a comprehensive national
disaster risk reduction and management platform
containing socio-economic statistics and geoinformation to improve capabilities of disaster
monitoring, early warning, risk assessment and
emergency rescue.
——Speech at Academician Council by Hu
Jingtao,Chairman of China
n DRR and DRM were proposed in Chinese 12th 5-Year
Plan.
4-Level Emergency Plan to disasters in China
n
n
n
4 levels are classified
according to hazards
degree;
Many departments
and local goverments
have their own duties
and tasks;
Almost all rescue
works are based on
Geo-referenced
Information System.
National Administration of Surveying Mapping
and Geo-information has the duty to provide GIS
Service for all departments concerned with DRR and DRM:
(1) State Council;
(2) Flood control and drought
relief office;
(3) Government of disaster
located;
(4) Army, Armed Police, Police;
(5) Ministry of Civil Affairs;
(6)etc.

n
n
n
High resolution and accuracy, large format
Designated exposure, GCPs are greatly reduced
Small size, light weight
Unmanned Aerial Vehicle(UAV) aerial photography system
n
Flexible, efficient and accurate
Emergency monitoring vehicles for geo-information
n
Intergration of image acquisition and remote transmission
RS data procession
n
n
Stereoscopic image model can be built raplidly for
disaster interpretation;
Processing 20Km2, 0.1-meter image data in 3 hours
with one workstation
Universal GIS software
n
n
n
n
Based on SOA and OGC web services standards;
Distribution and loose coupling between information
servers and end clients;
All socio-economic information geo-referenced can
be overlayed in the map on real-time;
End users can share and exchange their data by
releasing, registering and importing data in web
services mode.
Scalable
Architecture
Thematic GIS software for DRR and DRM
Disaster area in map view
and 3D view
Affected socio-economic
information query and statistics
Automated mapping and publishing
