1Spatial Explores Lessons for Australia from Transformation of Irish National Mapping Agency at WALIS Forum 2013

According to Gilroy, the latest spatial big data technologies could be a key enabler in delivering a solution to long-standing data quality issues affecting Australia’s cadastral map bases showing property boundaries and ownership. The Victorian Government, for example, commissioned a Sinclair Knight Merz report in 2011 which stated that Vicmap Property “does not meet the current or future needs and expectations of those government and private sector users who require high spatial accuracy”.

“This results in significant financial and productivity costs for direct users of the database, as well as the broader economy,” stated the SKM report, giving the example of a housing development in the urban fringe area of Melbourne where spatial information errors of up to 20m across the site resulted in costly delays and redesign works estimated to cost $1 million.

Spatial data inaccuracies relating to absolute position are not limited to the cadastral map base in Victoria but can also be found in other Australian states and in many other countries around the world, said Gilroy. “Surveyors using precise GPS need to shift the data they collect in the field to align it with property boundary information that often has acceptable relative accuracy but significantly variable absolute positional accuracy,” he said. “With advances in the management of spatial big data, however, new and more accurate survey data could be readily incorporated to improve the quality of existing cadastral map bases in a controlled manner over a reasonable timeframe.”

1Spatial has extensive experience delivering transformation, management and product generation for very large spatial databases in a number of National Mapping and Cadastral Agencies and other data publishers including Ordnance Survey Great Britain, Ordnance Survey Ireland, IGN France, GTS in Denmark, AdV in Germany and PSMA in Australia.

With the recent launch of 1Spatial Management Suite the component technologies to support all aspects of spatial big data management are now available as either stand-alone products or together as the 1Spatial Management Suite. Visitors to WALIS Forum 2013 will be able to visit 1Spatial and see a demonstration of 1Spatial Management Suite.

1Spatial Management Suite links together 1Spatial’s powerful and scalable product portfolio, enabling users to rapidly respond to real-time scenarios and ensure their data is always current, accurate and trustworthy. It allows users to increase productivity and reduce operational costs and risks by adopting an automated approach to data management. The suite is underpinned by enterprise database and Service Oriented Architecture technology from industry leaders including Oracle.
