NSW’s DCS Spatial Services has completed updates of the spatial cadastre for the local government areas of Albert and Girilambone, two small towns in Western NSW.
The upgrades address concerns that had been raised by residents about inaccuracies in the data.
According to DCS Spatial Services, the upgrades have not only improved the accuracy of property boundaries but also took into account the specific needs of each community.
For Albert, a little over 500 parcels were positionally improved, with the average shift being 65 metres. The magnitude of the shifts arose partly from the original digitisation process, during which maps of varying scales were combined and hand digitised. Albert just happens to be on the boundary of two 1:50,000 map sheets, meaning that an inaccuracy as small 1mm on paper could result in a displacement of 50 metres.
In Girilambone, the accuracy of property boundaries for more than 500 parcels was enhanced, resulting in shifts of over 20 metres.
DCS Spatial Services says its ongoing cadastral update program has so far positionally improved more than 1.3 million parcels across NSW, resulting in a better visual representation of property lines for residents and boosting accuracy within the NSW Spatial Cadastre.
