Land Parcel Methodology Land parcel methodology provides an opportunity for ABS to produce statistics that better support the information needs of Federal, State and Territory agencies. 1.Survey data can be integrated with other spatial information held by government and others (especially remotely sensed data) 2.Outputs can be tailored to regional management areas 3.Specific areas of interest can be surveyed in detail 4.Supports land accounting and in particular the production of cross classified tables

Issues Should land ownership be included in the “standard tables” of SEEA (especially since ownership/management by ISIC is in many cases a good proxy for land use)? If so, should more attention be given to land ownership and in particular registers of land ownership in SEEA (or is this more a matter for practical implementation)? Does land management need to be considered along with land ownership, use and cover?
