Whassup DAFWA? Spatial data in the Department of Agriculture and Food WA February 2010
Geographic Information Services Dedicated group within the Department since 1986. Role: To provide a spatial data service to support the business and activities of the Department and the wider Agricultural Industry. Part of Business Services Division, Information Services Branch. 13 permanent staff based in South Perth + Contractors. 15 staff based across nine regional offices. Software platform Intergraph GeoMedia. Major datasets stored in Oracle Spatial format, also GeoMedia warehouse (MS Access). Metadata maintained in Interragator+.
Major Custodial Datasets Client Property Database. Current extent of remnant vegetation. Pre-European vegetation. Soil-landscape/land system mapping. Land Use.
Client Property Database Landgate parcel data are the ‘building blocks’. Stored in Oracle Spatial. Available to all Department staff via intranet interface. Updated daily by GIS staff. Essential service to support the biosecurity and regulatory operations of the Department. Contact details restricted to Department use.
Current Extent of Native Vegetation Vector dataset captured using the best available aerial photo mosaics. Scale of capture in the process of being upgraded from 1:100, 000 to 1:20, 000. Distinguishes between native vegetation and plantations. Updated on a regular basis. Intersected with pre-European vegetation to obtain current extent by type dataset.
Scale status Date status Current Extent of Native Vegetation
Pre-European Vegetation Comprehensive vegetation map of WA. Scale of capture 1:250, 000 based on work of J.S. Beard. Compatible with National Vegetation Information System. Last updated 2005.
Soil-landscape/land system mapping Vector dataset captured from mapping carried out by DAFWA Land Resource Assessment Group and incorporating earlier mapping by CSIRO. Hierarchical system of mapping. Database of some 60,000 soil profile observations. Complete coverage of the agricultural area at subsystem/phase level. Scale of mapping varies from 1:50, 000 on the coastal plain to 1:250, 000 in the eastern wheatbelt. Comprehensive set of land quality and land capability attribution. Rangeland land system and Atlas of Australian Soils incorporated into a statewide dataset. WA layer in the Australian Soil Resource Information System
Soil-landscape mapping (cont.) Widely used for shire, regional and local planning purposes. Major information source for reports such as State of the Environment. Survey program complete but some areas are undergoing upscaling, occasional updates. Available to public via the SLIP NRM Info interface. Metadata maintained in Interragator+ on a survey basis and also a generic metadata statement for the complete dataset.
Land Use First produced for National Land and Water Resources Audit 2001. Property-based land use. 2006-Present project to map land use at sub-property level on a sub-catchment basis using aerial photo interpretation and limited field survey. Builds on perennial horticulture survey 2002-2005 and datasets from DAFWA and other agencies (reserves, current extent of native vegetation, town planning schemes etc.). Land use classified according to Australian Land Use and Management Classification V6. Data capture in progress as funding permits.
Other Projects/datasets BioSIRT – National biosecurity incident and surveillance data management system. Weed Watcher – Web-based portal for Australian Weeds Research Council. Climate mapping for monthly Department Seasonal Outlook. Pastoral lease infrastructure plans. Mapping and Spatial Analysis tasks in support of Departmental activities eg. Agri-business precinct location study, Drought reform pilot study, small landholder workshops, GM Canola growers.
