Abstract
One of the components of the FIRE-DST project is investigating fire modelling in the urban and peri-urban interface at the local neighbourhood scale. Each building in the interface will be examined to assess its vulnerability to the approach of a fire for each of ember attack, radiant heat and flame contact. The vulnerability will be dependant on a multitude of factors in the environment including the building construction, roof type, fences and other barriers. The vulnerability will then be used to calculate the expected impact of a fire on the urban area. To be able to model the fire movement and the affect on the built environment there has to be an accurate categorisation of the interface vegetation fuels. In this presentation we will focus on the creation of a 3D model of the neighbourhood scale vegetation and buildings. The neighbourhood scale environment will be created by including individual building information (like building age, wall construction type, roof type and occupancy) from the Geoscience Australia NEXIS database. There also has to be an accurate categorisation of the interface fuels and so specific details of other information such as individual trees, fences and forest will be obtained from high resolution LiDAR. LiDAR will also used to provide both the height and vertical profile of the vegetation in the urban interface. Other geographical information such as roads and a digital elevation model are also required. All this neighbourhood information is then processed to generate a 3D Model of the local environment.
