Access APINSW Imagery Theme Rapid Response – Floods Mar 2022Metadata Portal Metadata InformationContent TitleNSW Imagery Theme Rapid Response - Floods Mar 2022Content TypeAerial ImageryDescriptionRapid 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 recent flooding.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 August 2021 for this product type.Initial Publication Date11/03/2022Data 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).

APINSW影像主题快速响应数据集——2022年3月洪水 元数据门户元数据信息
内容标题:新南威尔士州影像主题快速响应数据集——2022年3月洪水
内容类型:航空影像
描述:快速响应影像通过采集与制作获取,用于识别可见地物与地形,旨在为极端自然灾害发生期间及灾后的应急管理决策提供支撑。本数据集覆盖近期受洪涝灾害影响的区域。此外,该快速响应影像产品可作为全政府层面的特定时间点地表景观的可视化记录,支持对多个采集时段的影像开展对比分析。本影像由空间服务部门(Spatial Services)使用徕卡测量系统(Leica-Geosystems)ADS80机载数字传感器采集项目区域的航线数据,经正射校正(ortho-rectifying)与镶嵌(mosaicing)处理生成。其中,ECW格式产品为标准彩色(RGB)正射镶嵌文件,JP2(JPEG 2000)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量。作为快速响应类产品,本数据集符合该产品类型于2021年8月制定的相关标准与精度规范。
