Victorian Flood History October 2022 Event Public

Polygon features representing the observed, derived or estimated inundation extent for floods that have occurred in Victoria. These are not linked to modelled flood data.Confirmed flood observations are derived from the automated and manual processing of data from the sources listed below. Note that while flood observations have manual oversight and corrections during the event, they are based on a point in time and may not necessarily represent the maximum flood extent.- - Aerial photography- - AIG observation- - Air observation- - Linescans- - GPS- - Ground Observer- - Satellite imagery interpretationsThe derived flood extent is from automated and manual processing of satellite data. This data is usually used to fill in gaps outside of areas covered by confirmed flood observations.Note that this flood extent data was prepared by the SCC Mapping Team for operational use only. It may have missing or incomplete data that could lead to gaps in analysis or visualisations. The dataset does not capture the peak flood extent in all areas. The dataset does not capture the extent of flash flooding.Past and future layers may be added as the data becomes available. List of events included in Supplemental Information本数据集包含维多利亚州已发生洪水的实测、衍生或估算淹没范围多边形要素，且未与模拟洪水数据关联。 经确认的洪水观测数据源自下述来源数据的自动化与人工处理流程： ——航空摄影 ——AIG观测 ——空中观测 ——线扫描数据 ——全球定位系统（GPS） ——地面观测员报告 ——卫星影像解译 需注意：尽管洪水观测数据在事件发生过程中会经过人工审核与修正，但该数据仅基于某一时间点的状态，未必能代表洪水的最大淹没范围。 衍生洪水范围数据源自卫星数据的自动化与人工处理流程，通常用于填补经确认洪水观测覆盖区域之外的数据空白。 需注意：本洪水范围数据由SCC制图团队仅为业务运营用途编制，可能存在数据缺失或不完整的情况，进而导致分析或可视化过程中出现数据空白。本数据集未覆盖所有区域的洪水峰值范围，亦未涵盖山洪暴发的淹没范围。 随着数据陆续可用，过往及未来的图层或将新增。本次纳入数据集的事件清单详见补充信息。
