Development of wireless sensor network equipped with GPS
for post-seismic building-wise damage identification is presented
in this paper. This system is called GPS on Every
Roof. Sensor node equipped with GPS antenna and receiver
is installed on the top of the roof of each and every building.
The position of this sensor node is measured before and after
earthquake. The final goal of this system is to i) identify the
displacement of the roof of each house and ii) collect the
information of displacement of the roof of the houses through
wireless communication. Superposing this information on GIS,
building-wise damage distribution due to earthquake can be
obtained. The system overview, hardware and some of the
key components of the system such as on-board GPS relative
positioning algorithm to achieve the accuracy in the order of
several centimeters are described in detail. Also, the results
from a field experiment using a wireless sensor network with
39 sensor nodes are presented.
