Eastern Bushlands Database VIS_ID 518

"Eastern Bushlands Database - Northern Region.\r\nRoberts, G. (1992). Vegetation systems of north east New South Wales: Mapped from Landsat TM imagery. NSW National Parks and Wildlife Service NEP 91 298.\r\nBroadscale Structural Vegetation mapping covering the eastern portion of NSW. The EBDB provides a broadscale management tool for conservation planning and decision making for purposes including stratifying field survey effort, regional planning, baseline estimation of clearing or regrowth rates, and as input to state-wide forest cover datasets.\r\n\r\nData was captured as part of the Save the Bush funded Eastern Bushlands Database project. The dataset consists of three complete portions covering eastern NSW - Northern, Southern and Central. The three separate datasets are similar but not enough to enable combining of them. Data should not be used at scales finer than 1:250 000.\r\n\r\nMapped using visual interpretation of Landsat TM satellite imagery. Attribute mapping includes structural vegetation information. Linework derived by visual interpretation of hardcopy Landsat TM imagery printed at 1:100 000. Polygons attributed by combination of visual interpretation and low intensity field work. Higher level of detail mapped in the Central Region, with a total of 53,592 polygons mapped (23,099 ,10 ha) as compared to the Southern Region (13,400 polygons mapped, 1,822 ,10 ha) and the Northern region (36,204 polygons mapped, 9,916 ,10 ha)."\r\n\r\nVIS_ID 518

东部灌丛数据库——北部区域。
G·罗伯茨（Roberts, G.），1992年。《新南威尔士州（New South Wales, NSW）东北部植被系统：基于陆地卫星专题制图仪（Landsat TM）影像制图》。新南威尔士州国家公园与野生动物服务局，文献编号NEP 91 298。
本数据集为覆盖新南威尔士州东部区域的大尺度结构植被制图成果。东部灌丛数据库（Eastern Bushlands Database, EBDB）可作为大尺度管理工具，应用于保护规划与决策制定，具体场景包括：分层统筹野外调查工作、区域规划、植被清除或恢复速率的基线估算，以及作为全州森林覆盖数据集的输入数据。
本数据为“拯救灌丛”（Save the Bush）资助的东部灌丛数据库项目的产出成果。数据集包含覆盖新南威尔士州东部的三个完整子区域：北部、南部与中部。这三个独立数据集虽存在相似性，但不足以直接合并使用。本数据的适用比例尺不得优于1:250000。
本数据基于陆地卫星专题制图仪（Landsat TM）卫星影像的目视解译完成制图。属性制图包含结构植被信息：线划要素由1:100000比例尺打印的纸质Landsat TM影像目视解译提取；多边形要素的属性通过目视解译结合低强度野外调查获取。中部区域的制图细节层级更高，共绘制53592个多边形斑块（对应23099个10公顷统计单元）；南部区域共绘制13400个多边形斑块（对应1822个10公顷统计单元）；北部区域共绘制36204个多边形斑块（对应9916个10公顷统计单元）。
