A planning scheme regulates the way land can be used or developed. A planning scheme has two parts: - text that sets out the requirements or standards for use and development, and - maps that show zones and overlays indicating where requirements or standards apply. The Tasmanian Planning Scheme overlays data comprises the overlays maps for those parts of the State where the Tasmanian Planning Scheme is in effect. The data is linked to the planning scheme text published online. The electronic planning map in, together with the electronic planning instrument, is the authorised version of the Tasmanian Planning Scheme under section 80M of the Land Use Planning and Approvals Act 1993.

The Tasmanian Planning Commission (TPC) has responsibility for maintaining the dataset to ensure data quality standards are preserved, to accommodate future overlay amendments, and to realign overlay boundaries to comply with ongoing changes to the state-wide cadastre where necessary. The dataset is continually being updated .

Planning schemes have been compiled by each Tasmanian municipality. TPC provided a set of business rules to guide construction of GIS layers. Council data was submitted to TPC between 2017-2021 for assessment. TPC specified additional data quality provisions to ensure the datasets conformed to the accuracy, consistency and completeness prerequisites required to publish the data on the Land Information System Tasmania (LIST) website. Positional accuracy: Overlay boundaries that are aligned with LIST parcel boundaries can be assumed to have the same positional accuracy as the parcels layer. The accuracy of overlay boundaries not aligned with parcel boundaries has not been estimated. Attribute accuracy: Overlay attributes have been checked by council and TPC and are estimated to be > 95% correct. Completeness: The layer is currently under construction Further information on planning schemes can be found on the Tasmanian Planning Commission website at https://www.planning.tas.gov.au/home
