Definition: For the purposes of this dataset a Waste Management Facility is defined as: A dedicated site where material is dumped, captured for recycling purposes and/or is reprocessed into another form.
Abstract: The Waste Management Facilities Database presents the spatial locations; in point format, all known waste management, recycling and reprocessing facilities within Australia.
National Map of Waste Management Facilities:
Lineage Statement: The waste management facilities dataset was digitized in 2012 from the library of imagery held within Geoscience Australia. Imagery used ranged from 0.15m to 2.5m resolution. Version 1 of the database was released publicly on Geoscience Australia’s website in July 2012 and was re-released as Version 1.1 in March 2017 following new information received from the Department of Environment. The waste management facilities web service – Version 1 was released in May 2016.
Source Information: The primary information source used to locate and compile the waste management facilities dataset were provided with the assistance of the following public and private agencies: 1. Local governments/councils 2. Australian Capital Territory Government - ACT No Waste 3. New South Wales State Government - Department of Environment, Climate Change and Water 4. Northern Territory Government - Natural Resources, Environment, the Arts & Sport 5. Queensland State Government - Natural Resources and Environment 6. South Australian State Government - Environment Protection Authority 7. Victorian State Government - Environment Strategies Unit 8. Western Australian State Government - Department of Environment and Conservation 9. Waste Management Association of Australia (WMAA) 10. Department of the Environment 11. Veolia Environment 12. Geoscience Australia – National Location Information Group
Positional (Spatial Confidence) Accuracy: Accuracy of the spatial data varies depending on the geographic location of the waste management facility and the accuracy of the imagery used to digitize the feature. The ‘Spatial Confidence’ attribute is a GIS specialist’s estimation/interpretation of the location accuracy of the digitized feature without taking into account the planimetric accuracy of the imagery used during the process. Values range from 1 to 5 and are assigned based on the following criteria: 5
4 3
2 1
Feature positively identified from imagery (expert ID) and, along with reliable reference material, feature located with 100% certainty; or expert ID from imagery or reliable reference material and individual knowledge sufficient to be 100% certain of location Feature positively identified from imagery (expert ID) but reference material insufficient to be 100% positive Feature placed on location of full address / known coordinates but can’t be positively identified from imagery; or feature placed on suspected location of facility identified from imagery, within a known, more general, location (such as a hospital grounds) Feature placed on street / general facility site Feature placed in the centre of district / town
Attribute Accuracy: The accuracy of the attribute information is reliant upon the data supplied by the sources outlined above. Where required, Geoscience Australia staff sought clarification from online sources to validate information.
Logical Consistency: Geoscience Australia used a Validation and Testing methodology to ensure the quality and compliance of the waste management facilities dataset. Testing is carried out using a mixture of computer programs and proprietary GIS packages (such as ArcGIS). Many of the tests are automated, using customised computer programs. These are supported by a detailed on-screen visual inspection of the digital data against available imagery and reference material for logical consistency and attribute accuracy. Where feature populations are small, or the validation tests are particularly important, the full population will be tested. Where feature populations are large, or a less stringent tolerance
applies, a Statistical Subset or Sample (Area) test may be used. Statistical Subset tests are a random selection of features from the whole population, whereas Sample tests assess features within a selected geographical area. Statistically acceptable procedures are adopted for tests that require sampling. The sampling procedures adopted are based on the Australian Standard AS1199-1988: "Sampling procedures and tables for inspection by attribute". The Acceptable Quality Level (AQL) is in the range of 0% to 5% against a defined technical specification.
Completeness: All waste management facilities compiled from information supplied by the primary information sources (refer to Source Information) have been digitised. Attribute information fields have been populated where data was available. Where there is no data available, incomplete fields are assigned a
value. Attribute fields will be updated or populated during future scheduled maintenance cycles if new information or updated information is identified and publically available.
Data Dictionary: Note: The following data dictionary table covers the full suite of attribute fields that define the Waste Management Facilities Database. Attribute names that are preceded by the ^ symbol are internal fields used for maintaining the data and are not included in the Waste Management Facilities Database accessible via Geoscience Australia’s data download website and web services.

Automatically generated system ID Geometry type (Point) A singled feature type “Waste Management Facility” is the collective name of the different facility subtypes identified in the CLASS field. Brief description of the feature type The feature type subtypes: • Landfill • Reprocessing • Transfer Station • Multi-Purpose A unique alphanumeric code The facility name of each individual feature A structure type identifier that describes the type of facility A description of the status of the landfill site: • Operational (functioning as a site for the dumping of accepted waste material) • Non-operational (no longer operational as a site for the dumping of accepted waste material) A description of the status of the reprocessing site: • Operational (functioning as a site for the reprocessing of waste) • Non-operational (no longer operational as a site for the reprocessing of waste) A description of the status of the transfer station: • Operational (functioning as a site for the transfer of waste) • Non-operational (no longer operational as a site for the transfer of waste) Operator of the facility Owner of the facility Planimetric accuracy of imagery used to capture or digitize the feature The address of this feature The suburb where this feature is located The state where this feature is located The source of the feature’s address information The name of the agency/data custodian for the source of this feature’s attribute information Date of the source material used to capture the feature’s attribute The name of the agency/data custodian for the source of the material used to capture the location of this feature

Data Maintenance: The next revision of this database will be determined by Geoscience Australia’s work program. This timeframe ranges between 1 and 5 years or by formal written agreement with Geoscience Australia.
Known Limitations of the Data: The waste management industry is undertaking a period of significant centralisation i.e. smaller outlying landfills becoming waste transfer stations that supply waste products into a larger, more centralised facility. Therefore, before using this information for commercial decisions please review the attributes for landfill, reprocessing and transfer stations.
