Description Description A Parcel Cadastre is a spatial representation of the legal land parcel boundaries within South Australia. The Plan/Parcel ID reference will be the primary key for each parcel. Delineation of current land parcels as registered on plans of division lodged with Land Services Division. For example, lot in plan (FP, DP, RP, CP, SP, GRO), Section in Hundred, Block or Section in Out of Hundreds. It comprises approximately 904220 parcels (20600 of which are outerboundaries of Community or Strata plans), 164500 Community and Strata parcels together with their legal identifiers.. The associated table structure is identical to that formerly available from DENR's EGIS. Unique Feature Identifier is PARCEL_ID. Usage Used for land administration, mapping and spatial analysis purposes generally. Can be linked to other databases either spatially or through the parcel identifier.

Data Quality Lineage The Parcel Cadastre was created to rationalise map based record maintenance within government and provide a single source of up-to-date mapping. The Parcel Cadastre was initially acquired during a four-year period (1984-1988) by digitising cadastral boundaries from the best available mapping. Most data was captured from maps at scale 1:2,500 in urban areas (400,000 parcels), and 1:10,000 or 1:50,000 in rural areas (350,000 parcels) with the remainder in pastoral areas and islands. Strata units were captured in 1999 using `heads up' digitising methods. These plans were digitally scanned at various scales. The Parcel Cadastre also provides a common and spatially consistent boundary framework for client use that promotes consistency among dependent data setsSELECT 1 FROM DUAL; thus facilitating improved data integration and analysis across government. The Parcel Cadastre is the fundamental reference layer for spatial information systems in South Australia. The Parcel cadastre is updated using ESRI ArcMap, Parcel Editor Completeness The Parcel Cadastre is updated in accordance with information detailed in plans deposited in Land Registration, Investment Management, Department of Planning Transport and Infrastructure(DPTI). These plans comprise subdivisions, roads opening and closing, re-designation of parcels and community plans. New parcel information is updated to the Parcel Cadastre within 2 weeks of receipt of the relevant information Positional Accuracy The positional accuracy of land parcel corners is dependent upon the scale of the historically captured source mapping and the subsequent digitising processes, either manual or input of PCPLANS files converted to XML. The accuracy of each boundary corner is described by an accuracy code. The code ranges from 0 to 7 (improved accuracy is reflected by descending number). On digital output, this accuracy code is attached to other feature types (eg. polygons). In some areas, the positional accuracy of land parcel corners has been improved from graphical accuracy to survey accuracy. These coordinate values have been derived by computation (Least Squares Adjustment for example) using plan measurements and tertiary network survey marks for control. A number of urban areas mainly around Adelaide have been spatially improved as part of a project. Spatial upgrades can be instigated as a result of client request.

Dataset Status Initially Acquired commenced 1984 Last Updated CURRENT Update Frequency Daily Maintenance Method Data entered using ESRI ArcMap Parcel Editor. XML converter program used to convert PCPLANS files. Generally, in spatially improved areas, data is entered INTO preselected cadastral extent covering the block the new parcels are in and extending to cover the next adjacent blocks. Once entered, a least squares adjustment is performed. In areas not spatially improved, generally the parent and adjoining parels are extracted and the new data entered. no least square adjustment is performed. AusGOAL Restricted
