Abstract
A review of the methods employed to collect 'buildings specific field data' following the impact of Severe Tropical Cyclone Larry (March 2006) resulted in a plan to build a vehicular mounted rapid data inventory collection system to compliment post disaster surveys. The system assists to overcome the issues related to restricted access, poor weather and difficult working conditions. The ability to quickly collect comprehensive information which is highly critical for both damage assessment and vulnerability model validation reduces assessment errors caused by rapid clearing of debris and repairs following the disaster, along with the use of tarpaulins, which often obscure the level of damage viewed from the street. The Rapid Inventory Collection System (RICS) consists of four 5 Megapixel Gigabit Ethernet digital cameras operating at approximatly four frames per second. The high-resolution cameras, enclosed within all weather housings, are attached to an extendable aluminium tripod with either suction cup or magnetic 'feet' which can be attached to a 4WD dual cab roof or tray. The cameras stream images which are captured via a five port Gigabit Ethernet switch supporting jumbo frames to reduce the CPU load required to handle incoming data to a Quad Core processor Laptop. The images are compressed in jpeg format 'on-the-fly' and displayed in a Graphical User Interface (GUI) along with GPS location, bearing and speed. An additional display window shows the street-directory (UBD) roadmap and a GPS tracklog. Hot keys for instant damage assessment marking location and damage levels have been programed into the GUI. All images are time synchronised and stored in a geo-referenced database for spatial analysis to estimate the damage.
