Generations of Data Quality – What’s Next

  • Michael Dixon, PSMA Australia, Australia
  • Ashley Mahar, GeometryIT, Australia
  • The proliferation of spatial applications across more and more critical disciplines is driving the demand for improvements in spatial data quality at a furious rate. The presentation will briefly examine the early generations of spatial data quality initiatives that have formed a platform for the current advances. The demands and challenges that are shaping the spatial data requirements of the future will also be discussed in the context of their impact on current paradigms, systems and practices. As a supporting case study the examination will catalogue PSMA Australia’s journey through the evolution of data quality improvements to their national datasets. Particular attention will be focussed on the challenges that have been addressed when dealing with multiple data contributors, large volumes of data and how automation through the LYNX system has been used to manage and enhance the overall process. The discussion will also focus on the emerging demands and their implications for the current work flow and infrastructure. The presentation will conclude with an analysis of PSMA Australia’s vision for the next generation of spatial data quality initiatives and the associated strategies and processes required to service the changing needs a rapidly maturing spatial information market.
