State Vegetation Type Map: Western Region v1.0. VIS_ID 4492

This dataset was superseded by the State Vegetation Type Map (https://datasets.seed.nsw.gov.au/dataset/nsw-state-vegetation-type-map) on 24.06.2022.\r\n\r\nPlease note, Western Region v1.0. VIS_ID 4492 web service and zipped dataset will be archived and will no longer be available on line after 31st March 2025.\r\n\r\nThe NSW Office of Environment and Heritage (OEH) is producing a new map of the State’s native vegetation. This seamless map of NSW’s native vegetation types will enable government, industry and the community to better understand the composition and the relative significance of the native vegetation in their local area.\r\nThe State Vegetation Type Map (SVTM) (http://www.environment.nsw.gov.au/vegetation/state-vegetation-type-map.htm) is constructed from the best available imagery, site survey records, and environmental information.\r\n\r\nThe primary thematic layer in this dataset is a regional scale map of Plant Community Type (PCT) - "quickview" map. This Version 1.0 release is comprehensive revision of the interim version 0.1 released in 2016. \r\n\r\n- - -\r\n\r\nA summary of the revisions are listed below:\r\n\r\n* An established one-to-one relationship between PCT and Vegetation Photo Pattern (vegStruct)\r\n* Integration of existing mapping, including: \r\n\r\n * VIS_ID 4186 - Survey and mapping of Darling floodplain vegetation communities in 2014\r\n * Balonne mapping 2016 (VIS_ID 4453)\r\n * Darling mapping 2016 (VIS_ID 4454\r\n\r\n* Manual revision of Vegetation Photo Pattern (VPP’s, vegStruct) with Aerial Photo Interpretation of time series enhanced time-series 2.5m SPOT 5 imagery\r\n* Reprojection of PCT models across updated VPP’s.\r\n* Manual revisions of individual PCT’s with Aerial Photo Interpretation of time series enhanced time-series 2.5m SPOT 5 imagery\r\n* Addition of the following PCT’s:\r\n\r\n * 5: River Red Gum herbaceous-grassy very tall open forest wetland on inner floodplains in the lower slopes sub-region of the NSW South Western Slopes Bioregion and the eastern Riverina Bioregion\r\n * 8: River Red Gum - Warrego Grass - Couch Grass riparian tall woodland wetland of the semi-arid (warm) climate zone (Riverina Bioregion and Murray Darling Depression Bioregion)\r\n * 21: Slender Cypress Pine - Sugarwood - Western Rosewood open woodland on sandy rises mainly in the Riverina Bioregion and Murray Darling Depression Bioregion\r\n * 44: Forb-rich Speargrass - Windmill Grass - White Top grassland of the Riverina Bioregion\r\n * 82: Western Grey Box - Poplar Box - White Cypress Pine tall woodland on red loams mainly of the eastern Cobar Peneplain Bioregion\r\n * 130: Horse Mulga - Umbrella Mulga shrubland on ranges in the arid and semi-arid climate zones\r\n * 133: Western Bloodwood - Whitewood low open woodland on Tibooburra Granite\r\n * 135: Coobah - Western Rosewood low open tall shrubland or woodland mainly on outwash areas in the Brigalow Belt South Bioregion\r\n * 140: Broombush shrubland in dunefields of the arid climate zone\r\n * 151: Sandhill Cane Grass hummock grassland on siliceous sands on dune crests of the arid zone\r\n * 167: Kerosene Grass - Mulka grass - short grassland/forbland of the arid zone\r\n * 176: Green Mallee - White Cypress Pine very tall mallee woodland on gravel rises mainly in the Cobar Peneplain Bioregion\r\n * 181: Common Reed - Bushy Groundsel aquatic tall reedland grassland wetland of inland river systems\r\n * 189: Ephemeral forbland wetland of low-saline lake-beds of the arid and semi-arid (warm) climate zones\r\n *190: Mallee Box open woodland mainly in the Murray Darling Depression Bioregion\r\n * 196: Australian Boxthorn open shrubland in the semi-arid or arid climate zones\r\n * 200: River Red Gum woodland wetland of lake fringes in the semi-arid (hot) and arid climate zones\r\n * 205: Marsh Club-rush wetland very tall sedgeland of inland watercourses, mainly Darling Riverine Plains Bioregion\r\n * 206: Dirty Gum - White Cypress Pine tall woodland of alluvial sand (sand monkeys) in the Darling Riverine Plains Bioregion and Brigalow Belt South Bioregion\r\n * 208: River Red Gum low woodland of rocky gorges and creeks in the Cobar Peneplain\r\n * 220: Purple Wood (Dead Finish) wattle shrubland of the arid zone sandplains\r\n * 222: Low Bluebush - Bladder Saltbush open shrubland of the arid zone\r\n * 231: Coolabah open woodland wetland dunefield depressions of the arid zone\r\n * 240: River Coobah tall shrubland wetland of the floodplains in the Riverina Bioregion and Murray Darling Depression Bioregion\r\n * 242: Rats Tail Couch sod grassland wetland of inland floodplains\r\n * 250: Derived tussock grassland of the central western plains and lower slopes of NSW\r\n * 261: Swamp Paper-bark shrubland wetland ringing depressions in the Mulga Lands Bioregion\r\n * 264: Supplejack woodland of the NSW north-western semi-arid plains\r\n * 359: Porcupine Grass - Red Mallee - Gum Coolabah hummock grassland / low sparse woodland on metamorphic ranges on the Barrier Range, Broken Hill Complex Bioregion\r\n * 375: Budda Pea - Channel Millet ephemeral reedland wetland on floodplains in north-western NSW\r\n * 630: Black Box - Silver Saltbush chenopod open woodland on terrace rises on alluvial plains in the lower Darling River and lower Murray River region of the Murray Darling Depression Bioregion\r\n * 1203: Speargrass natural grassland of the sandplains of the Murray Darling Bioregion\r\n\r\n- - -\r\n\r\nQuickView map fields:\r\n\r\n* PCTID – Plant Community Type identifier.\r\n* PCTName – Plant Community Type common names\r\n* vegClass – The PCT’s Keith Class\r\n* vegFormation – The PCT’s Keith Formation\r\n* mapSource - The source of the polygon’s PCT attribution. \r\n* MapName – The 100k sheet map name\r\n\r\nNote that this is a dissolved surface and does not highlight the fine internal line-work within each map unit.

本数据集已于2022年6月24日被《新南威尔士州植被类型图》（https://datasets.seed.nsw.gov.au/dataset/nsw-state-vegetation-type-map）取代。

请注意，西部地区v1.0版本（VIS_ID 4492）的网络服务及压缩数据集将于2025年3月31日后归档，不再在线提供。

新南威尔士州环境与遗产办公室（NSW Office of Environment and Heritage, OEH）正在制作该州原生植被的新版地图。这份覆盖新南威尔士州的无缝原生植被类型图，将帮助政府、行业及社区更好地理解其所在区域原生植被的组成及相对重要性。
《新南威尔士州植被类型图》（State Vegetation Type Map, SVTM）（http://www.environment.nsw.gov.au/vegetation/state-vegetation-type-map.htm）基于现有最优影像、实地调查记录及环境信息构建而成。

本数据集的核心主题层为区域尺度的植物群落类型（Plant Community Type, PCT）“快速查看”地图。本次发布的v1.0版本是对2016年发布的临时版v0.1的全面修订。
