GNSS Support for Christchurch Earthquake Relief
Christchurch, New Zealand, has recently suffered not one but two major earthquakes, in September 2010 and February 2011, which created devastation in the city centre and eastern suburbs.
Even today, some five months later, a significant area of the inner city is still inaccessible. The CHC X91 GNSS receiver deployed by a Paterson Pitts Group survey team on two key projects has contributed to enabling decisions about how the planned reconstruction of Christchurch should proceed.
Several thousand houses near the Avon River and estuary which have been damaged by the earthquake and resulting liquefaction are likely to never be rebuilt. When undertaking decisions of this magnitude, it is essential to have high-quality data.
