Boundaries were either provided as spatial data, compiled using cadastral boundary, roads or rivers layers, digitized from hand drawn maps or plotted using textual descriptions.

The accuracy of the boundaries copied from existing GIS data vary from less than 1m to 500m. The existing GIS data scale ranged from 1:1,000 (ACT) to 1:500,000 (northern WA).

All anomolies were corrected by ERIN in consultation with the IPA Programme staff. Attributes in the IPA dataset are a subset of CAPAD attribute fields and are as follows: NAME: official (gazetted) name of a IPA or unofficial name. Gazetted IPA's with no name are flagged as "Unnamed". TYPE: official gazetted designation of the IPA. STATE: State the IPA is located in. STATUS: whether the IPA is declared or undeclared. GAZ_AREA: area of IPA in hectares as described in the nomination document (eg. parliamentary gazettal or nomination letter to the IPA Programme), to the nearest hectare. GIS_AREA: area of IPA in hectares as calculated in ArcGIS using the Australian Albers Equal Area projection. Where IPA's are made up of multiple polygons (parts) the GIS_AREA is the sum of all the polygons. IUCN: the IUCN protected area category described by the Managing authority, as outlined in the publication: CNPPA/WCMC "Guidelines for Protected Area management categories". Gland: IUCN, 1994. (ISBN: 2-8317-0201-1). IUCN Definitions include: IA Strict Nature Reserve: PA managed mainly for science; IB Wilderness Area: PA managed mainly for wilderness protection; II National Park: PA managed mainly for ecosystem protection; III Natural Monument: PA managed mainly for conservation of specific natural features; IV Habitat / Species Management Area: PA managed mainly for conservation through management intervention; V Protected Landscape / Seascape: PA managed mainly for landscape/seascape conservation and recreation; VI Managed Resource Protected Area: PA managed mainly for the sustainable use of natural ecosystems. AUTHORITY: This attribute contains code sets for the management authority of the IPA. Definitions include: IMG = Indigenous Management Group LILC = Local Indigenous Land Council TSRA = Torres Strait Regional Authority GAZ_DATE: original gazettal/ proclamation date. LATEST_GAZ: Date of most recent gazetted amendment or verification. ENVIRON: Where an IPA component comprises of land (T=terrestrial) or sea country (M=marine). SOURCE: Source of spatial dataset (eg. CAPAD_T). Definitions include: Cadlite = Cadastral parcels, as supplied by the Public Sector Mapping Authorities [PSMA] Cons = Consultant / Third party contractor CAPAD_T = Terrestrial component of CAPAD DLI = WA Land Information Authority (Landgate) DPIPWE = Tas Dept of Primary Industries, Parks, Water and Environment IMG = Indigenous Management Group NNTT = National Native Title Tribunal NRETAS = NT Dept of Land Resource Management (formerly the Dept of Natural Resources, Environment, the Arts and Sport) NRSP = National Reserve System Program, DSEWPaC COMMENTS: Any comments, change of name, etc

Attribute data conform to a subset of the nationally agreed CAPAD specifications. All source datasets which were not consistent with the CAPAD standards were corrected as required.

Spatial data of source datasets were checked and corrected for mismatches across jurisdictional boundaries (see lineage for further details).

All polygons were given visual checks for spatial errors and for appropriate attribute information.

All Declared IPA's are complete to the revision date of this dataset.
