Open data: NSW Globe adds residential sales history

Government project gets more data

The NSW government has added sales history data for residential properties to its NSW Globe project and will release the data in an open format for use by third parties.

NSW Globe was launched last year by state government agency Lands and Property Information. The project allows government datasets to be overlaid on Google Earth.

NSW Globe includes medium and high resolution aerial and satellite imagery from government and private sources, terrain data, historic images, boundary information, including suburbs and electorate information, roads and rail routes, and addresses.

"Today we are meeting our election commitment to make sales data available for free and in an open format by the end of October 2015," the state's finance minister, Dominic Perrottet, said in a statement.

"Consumers expect the latest information at their fingertips anywhere, any time — we are pleased to help them make affordable and informed choices when buying and selling property."

The government will also by the end of next month make the data available to third parties

The sales data dates back to 2001.

"Until now, people had to pay the government or a third party provider to access property sales data,” Perrottet said.

"The NSW government recognises that in a booming property market, buyers and sellers are entitled to accurate and accessible land and property information."

The state government last year unveiled its geospatial data strategy.

The five-pronged NSW Location Intelligence Strategy (PDF) aims to promote the creation and use of geospatial data, including by adding location information to key NSW economic, social and environmental datasets.

Its launch was preceded in 2013 by the government's open data policy.

Under the NSW Government Open Data Policy, agencies begin "from a position of data openness, with the prerogative in favour of data release" unless there is a "specific, overriding" reason to not release data.
