We present the first detection of the Galactic aberration in 8-GHz astrometric observations of extragalactic radio sources by geodetic VLBI. We analyzed the full geodetic VLBI observational data base to derive source proper motion and we fitted dipolar and quadrupolar vector spherical harmonics coefficients to the velocity field. Our results are in good agreement with theoretical prediction and constitute the first observation of this very tiny effect

This dataset attempts to reflect the boundaries of claimant applications for Native Title as per the Register of Native Title Claims (s185, Native Title Act; Commonwealth). This is a national dataset but data is stored by jurisdiction (State), for ease of use. Applications stored for each jurisdiction dataset include applications which overlap into adjoining jurisdictions as well as applications which overlap with these. This dataset depicts the spatial record of registered claimant applications. Aspatial attribution includes National Native Title Tribunal number, Federal Court number, application status and the names of both the NNTT Case Manager and Lead Member assigned to the application. Applicants of registered applications have the Right To Negotiate (RTN) with respect to certain types of Future Acts over the area being claimed. Whilst applications that are determined are recorded on a separate register, all registered applications remain on the Register of Native Title Claims until otherwise finalised. Geospatial data portraying native title information produced by the National Native Title Tribunal may not be on-sold.

This dataset reflects the external boundaries of all native title determination and compensation applications that are currently recognized and active within the Federal Court process. Applications that are non-active (i.e. withdrawn, dismissed, finalised, rejected or combined) are only included as aspatial records for completeness. This is a national dataset with data partitioned by jurisdiction (State), for ease of use. Applications stored for each jurisdiction dataset include applications which overlap into adjoining jurisdictions as well as applications which overlap with these for completeness. This dataset depicts the spatial definition of active Claimant and Non-claimant native title determination applications and compensation applications. Where possible these may include internal boundaries or areas excluded. Aspatial attribution includes National Native Title Tribunal number, Federal Court number, application status and the names of both the NNTT Case Manager and Lead Member where assigned to the application. Applications included on the Schedule of Native Title (Federal Court) include all registered and unregistered applications as well as determined applications that are yet to be finalized.

The annual Asia Pacific Regional Geodetic Project (APRGP) GPS campaign is an important activity of the Geodetic Technologies and Applications Working Group (WG) of the Permanent Committee on GIS Infrastructure for Asia and the Pacific Region (PCGIAP). This document overviews the data analysis of the APRGP GPS campaign undertaken in 2010. The GPS data was processed using version 5.0 of the Bernese GPS Software in a regional network together with selected IGS (International GNSS Service) sites. The GPS solution was constrained to the ITRF2005 reference frame through adopting IGS05 coordinates on selected IGS reference sites and using the final IGS earth orientation parameters and satellite ephemerides products.

Hydrodynamic models based on the shallow water equations are commonly used for tsunami, storm surge and flood risk assessment. For a hypothetical inundation event, such models can provide estimates of the extent of inundation, as well as water depth and velocity over time. These outputs may be linked with exposure and vulnerability models to estimate the damage associated with the inundation event, thus providing useful information to inform emergency management. One such model is ANUGA, developed by the Australian National University and Geoscience Australia. ANUGA approximately solves the 2D shallow-water equations on an unstructured mesh using a 'shock-capturing' finite-volume method. This shock-capturing capability is critical for modelling inundation events with rapid changes in flow properties, such as tsunami bores, dam break floods, and moving wet-dry fronts. This is because even in the presence of flow discontinuities, the model can correctly calculate the propagation speed of the discontinuity. Without this shock-capturing capability, the model will generate significant errors in the computation of shock speeds, such as the travel times of dam-break flood waves and steep tsunami. Mathematically, ANUGA's shock-capturing algorithm requires that terms in the shallow water equations representing the effect of water pressure gradients are split into two components: 1) a term including the influence of the bed slope, and 2) a term including the influence of flow depth gradients. Because these two terms are discretized separately, numerical difficulties can arise in situations when they should exactly balance each other (e.g. water at rest in a lake). In some modelled scenarios, these errors can lead to unphysical predictions, such as water "creeping" up the sides of buildings or wharfs, and high velocities at the edges of stable wet-dry fronts. Here I describe the implementation of a 'well-balanced' treatment of the pressure gradient in ANUGA, which ensures the exact cancellation of the pressure gradient terms when the water surface is flat. This involves the use of an alternative bed-slope discretization and novel adjustments to the treatment of partially wet cells. The adjusted model is shown to give improved predictions in a range of situations, and subject to further testing, may provide a useful enhancement to ANUGA.
