Description

Abstract:

The National Waste Management Database (upgraded) presents the spatial locations of Australia's known landfills, waste transfer stations and a large number of waste reprocessing facilities. The data are a compilation of Australian, jurisdictional government, council and industry databases.

The purpose of the National Waste Management Database is to support decision makers from industry, governments and other interested parties make better, and more informed decisions based on evidence based information.

The National Waste Management Site Database fields include:

NAME - Name of the feature.

LANDFILL - Landfill classification (Closed, Not Applicable, Operating, Unknown)

REPROCESSING - Recycling plant classification (Closed, Not Applicable, Operating, Unknown)

TRANSFERSTATION - Transfer station classification (Closed, Not Applicable, Operating, Unknown)

OPERATOR - Operator of the facility

OWNER - Owner of facility

SITEID - Geoscience Australia generated unique ID for feature

SITEADDRESS - Street address of feature

SITESUBURB - Suburb feature located in

POSTCODE - Postcode for feature

STATE - State feature located in

FEATURERELIABILITY - Reliability/currency date of FEATURESOURCE

FEATURESOURCE - Image or file name used to validate/digitize feature

ATTRIBUTERELIABILITY - Reliability/currency date of ATTRIBUTESOURCE

ATTRIBUTESOURCE - Authority, Organisation sourced for validating feature

PLANIMETRICACCURACY - Planimetric accuracy of image used to digitize the feature

SPATIALCONFIDENCE - 1 to 5 (1 bad - 5 excellent) rating of spatial and attribute data

Lineage:

The waste management points were digitized in 2010/11/12 from the library of imagery held within Geoscience Australia. Imagery used ranged from 0.15m resolution aerial photos to 2.5m resolution satellite images. Each entry in the database lists the imagery source.

Source Information

Geoscience Australia compiled this database with the assistance of the following:

- Local governments / councils

- Australian Capital Territory Government - ACT No Waste

- New South Wales State Government - Department of Environment, Climate Change and Water

- Northern Territory Government - Natural Resources, Environment, the Arts & Sport

- Queensland State Government - Natural Resources and Environment

- South Australian State Government - Environment Protection Authority

Positional accuracy:

The accuracy of the data varies depending on the geographic location of the points and the accuracy of the imagery used to digitize the points.

The spatial confidence field provides an estimate of the accuracy of the digitized points without taking into account the planimetric accuracy of the imagery used during the process. Values range from 1 to 5 with 1 assigned to points whose position is unknown (not visible on the imagery), and 5 assigned to points whose position was able to be digitized precisely from the imagery. If no imagery was available for a point, its position was estimated from information found in publicly available online resources and it was assigned a spatial confidence of 1.

The planimetric accuracy of the imagery used ranged from 0.15m to 25m with an average of approximately 8m. Imagery covering areas of low population generally had lower accuracy.

Attribute accuracy:

The attributes for; 'landfill', 'waste transfer station', 'reprocessing facility', 'owner' and 'operator' were primarily assigned through research from council or industry websites and annual reports. Where field values are equal to NULL, the values either do not exist or have not been made publicly available by the owner or operators. Geoscience Australia has made every effort to ensure the accuracy of the attribute information.

Note: It should be noted that as of 2012 the waste management industry is going through a period of significant centralisation i.e. smaller outlying landfills becoming waste transfer stations that supply waste into a larger more central facility. Therefore, before using this information for commercial decisions please review the attributes for; 'landfill' and 'waste transfer station'.

Logical Consistency:

The National Topographic Database (NTDB) uses a Global Identifier (GlobalID) attribute to identify individual features inside the database. This GlobalID is unique on a national basis and is expected, in conjunction with a field named Revised to maintain a currency status of edits in the database during its formation and maintenance.

The GlobalID is assigned to each feature as the database is populated. The GlobalID will be maintained by the database functionality and will remain stable during the majority of attribute and spatial adjustments to a feature. The GlobalID consists of 36 characters enclosed in curly brackets (eg '{EB07A3A0-A7C3-4A84-AA29-BCE26FDA6838}').

Geoscience Australia uses a Validation and Testing methodology to ensure the quality and compliance of all data derived from the NTDB.

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 on-screen visual inspection of the digital data against imagery and reference material for logical consistency and attribute accuracy.

Where feature populations are small, or the 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:

This national database represents all known waste management sites provided by the primary information sources (lineage) as of June 2012.

Revision Notes:

This database is a revision of the National Waste Management Database released in 2011. Notable improvements of the database are:

- Addition of approximately 400 previously unknown waste management sites; predominately rural sites.

- Revision of the status and location of approximately 700 lower confidence sites.

Next Revision:

The next revision of this database will be determined by Geoscience Australia?s work program. This timeframe will range between 3 and 5 years; this is dependant upon resources and other priorities.
