Overview
This screening layer compares exposure to coastal flooding using a common set of terrain, settlement and scenario indicators. It is designed to make planning assumptions visible before a detailed assessment.
The index is a comparison aid, not a forecast or regulatory determination. Component layers remain available for inspection.
Method
Terrain, settlement and scenario surfaces are normalised to a common grid and combined into an exposure class. Each component retains its source date, scale and interpretation note.
Field guide
| Field | Description |
|---|---|
exposure_class |
Relative exposure class for the cell. |
scenario_year |
Scenario horizon represented. |
terrain_source |
Source used for the elevation surface. |
review_note |
Interpretation and limitation note. |
Known limitations
Scenario assumptions and terrain resolution strongly influence the result. Use the component layers and local studies before making site-level decisions.
概览
这份筛选图层使用统一的地形、聚落和情景指标比较滨海洪涝暴露程度，旨在详细评估前让规划假设更加透明。
该指数用于比较辅助，不是预测结果或监管认定。各组成图层仍可单独检查。
方法
地形、聚落和情景表面被标准化到共同网格，并合成为暴露等级。每个组成部分都保留来源日期、比例尺和解读说明。
字段指南
| 字段 | 描述 |
|---|---|

解读和局限性说明。 |
已知局限
情景假设和地形分辨率会显著影响结果。进行站点级决策前，请结合组成图层和当地研究。
