NEXIS (National Exposure Information System) Residential Dwelling Density is a set of four raster layers representing the density of residential dwellings across Australia at different scales and resolutions. Resolutions include 2km, 1km, 500m and 100m. The Australian Bureau of Statistics (ABS) defines dwelling units as self-contained suites of rooms including cooking and bathing facilities and intended for long-term residential use. Such dwelling units include houses-detached buildings used for long-term residential purposes-and other dwellings including flats. This product is based on NEXIS version 13 (2022) data.

Papua New Guinea (PNG) sits at complex boundary between three major tectonic plates and eight microplates. As a result of this setting, the region experiences significant seismic activity that gives the country a hazard that ranges from low in the south west of the country up to very high by global hazard levels found at plate boundaries. This hazard has been long recognised and the suite of building standards released in 1982 contain provisions to impart resilience to buildings that were based on the best understanding of seismic hazard available at that time. The associated design methodologies in the standards also embody design methodologies that reflect the then current seismic design practice including requirements for achieving structural ductility in design using a range of structural materials. With a bedrock hazard that varies across the country, the overall objective of the suite of standards is that the design provisions impart properly constructed buildings with a strength and toughness compatible with the local hazard severity.

This web service shows areas or locations occupied by an existing high-density urban development or known individual building structures in peri-urban and remote locations. Data used in this service is of varying levels of coverage and quality since it is aggregated from a variety of sources. The intended purpose of the service is to provide preliminary, first-pass information about urban environment, building structures and their distribution in landscape, as one of constraints on future development. Users should carry out further and more detailed investigations because this information is not meant to be a definitive source or support engineering phase planning. The service has layer scale dependencies.
