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

罗伯茨（Roberts, G.）于1992年完成的研究《新南威尔士州东北部植被系统：基于陆地卫星TM（Landsat TM）影像的植被制图》，由新南威尔士州国家公园与野生动物服务处发布，报告编号NEP 91 298。

本数据集为覆盖新南威尔士州东部区域的大范围结构植被制图成果。东部灌丛数据库（Eastern Bushlands Database, EBDB）可作为大范围管理工具，应用于保护规划与决策制定，具体场景包括分层开展野外调查工作、区域规划、估算林地清理或自然恢复速率的基线数据，以及作为全州森林覆盖数据集的输入数据源。

本数据集是“拯救灌丛”（Save the Bush）资助的东部灌丛数据库项目的产出成果。该数据集包含覆盖新南威尔士州东部的三个完整分区：北部、南部与中部。这三个独立数据集虽具有相似性，但尚不具备合并条件。本数据集不得在比例尺精细于1:250000的尺度下使用。

本数据集通过对陆地卫星TM卫星影像的目视解译完成制图。属性制图涵盖结构植被相关信息。线要素通过对打印为1:100000比例尺的纸质陆地卫星TM影像进行目视解译提取。多边形的属性通过目视解译结合低强度野外调查进行赋值。中部区域的制图细节程度更高，共绘制53592个多边形（对应23099个10公顷地块）；南部区域绘制13400个多边形（对应1822个10公顷地块），北部区域绘制36204个多边形（对应9916个10公顷地块）。
