Access APINSW Imagery Theme Rapid Response – Historical Floods 2012 and 2016Metadata Portal Metadata InformationContent TitleNSW Imagery Theme Rapid Response - Historical Floods 2012 and 2016Content TypeHosted Feature LayerDescriptionRapid response imagery is captured and produced to identify visible features and terrain in order to support emergency management decision making during and after adverse natural events. In this case the imagery covers areas affected by historical flooding events in 2012 and 2016.Additionally, the rapid response imagery product is used on a whole of government basis as a visible record of the landscape at a given point in time, allowing for comparative analysis to be carried out over multiple capture dates. The imagery was created by ortho-rectifying and mosaicing data from flight lines over the project area captured by Spatial Services using a Leica-Geosystems ADS80 airborne digital sensor. An ECW product is created as a Standard Colour (RGB) orthorectifed mosaic file and a JP2 file is created as a False Colour (NRG) orthorectified file. The file size depends on the individual project area, compression ratio and the number of bands that exist in the image.As a rapid response product, this dataset meets the standards and accuracy specifications outlined in December 2016 for this product type.Spatial Services captures and updates imagery from advice provided by stakeholders primarily through Imagery and Elevation NSW, a working group of the NSW Location Leadership Group.Initial Publication Date31/03/2021Data Currency01/01/3000Data Update FrequencyOtherContent SourceData provided filesFile TypeESRI File Geodatabase (*.gdb)Attribution© State of New South Wales (Spatial Services, a business unit of the Department of Customer Service NSW).

内容标题:新南威尔士州影像主题快速响应——2012与2016年历史洪水
内容类型:托管要素图层(Hosted Feature Layer)
描述:快速响应影像通过采集与制作,用于识别可见地物与地形,以支持灾害自然事件发生期间及事后的应急管理决策。本数据集覆盖2012年与2016年历史洪涝灾害影响区域。
此外,该快速响应影像产品可作为全政府范围内特定时间点的地表可视化记录,支持对多期采集影像开展对比分析。本影像由空间服务局(Spatial Services)使用徕卡地理系统(Leica-Geosystems)ADS80机载数字传感器(airborne digital sensor)对项目区域内的飞行航线数据进行正射校正(Ortho-rectifying)与镶嵌(Mosaicing)后生成。其中ECW格式产品为标准彩色(RGB)正射镶嵌文件,JP2格式产品为假彩色(NRG)正射校正文件。文件大小取决于具体项目区域、压缩比及影像波段数。
作为快速响应类产品,本数据集符合该类产品2016年12月发布的标准与精度规范。空间服务局主要通过新南威尔士州位置领导小组(NSW Location Leadership Group)下属工作组——新南威尔士州影像与高程工作组(Imagery and Elevation NSW)收集的利益相关方建议,开展影像采集与更新工作。
