This is a seamless mosaic of the 76 pages of "Sprents Book" which was a survey of Hobart Town that was started on February 25th 1841. James Sprent was born in 1808. He was a graduate of Glasgow University who arrived in the Colony (Tasmania) in 1830. There are a number of reports which substantiate the fact that he was stationed in Hobart for various periods somewhere between circa 1837 to 1846, where on February 25th 1841 he undertook an extensive and large scale survey of the greater part of Hobart Town. The extent of that survey could best be described as extending from the Brooker Highway north to Burnett Street, south along Arthur Street to Knocklofty Terrace, east to DâArcy Street in South Hobart along the Sandy Bay Rivulet through to Battery Point around the Wharf area and back to the Brooker Highway. This was done between the time of his first attempt at a Trigonometrical Survey of Tasmania between 1833 to 1837 and on resumption some 10-years on, in 1847. Sprent produced a set of 76 street plans at

It is generally thought that the Sprents Book was split, in about the late 1960âs and each individual page was then carefully mounted on a durable thin cardboard backing, presumably for easy handling and storage. All individual plans were scanned in colour at high resolution in 2004, as part of a forerunner to the Information and Lands Services Division Archiving Strategy. Images from these pages were georeferenced in 2010 to fit the current digital cadastral fabric and images cropped generally along street boundaries to remove overlaps between pages whilst ensuring the maximum amount of detail was preserved. These images were mosiaced into a single ECW image in February 2011. The original pages of Sprents Book were handed over to the State Archives Office in mid 2011.

This is a historical reference layer, however positional accuracy would be in the vicinity of within 5 to 10 metres of true position.
