DP Bird Strike Mitigation (OpenData)

This entity describes the area surrounding an airport runway where rules exist in the district plan to control or restrict specific activities which are likely to encourage bird flight movements, which in turn may pose a threat to aircraft operations. The geometries are derived by buffering out around the airport runway and clipping to the Christchurch District TLA boundary. This entity is intersected with RatingUnit to enable generation of property condition comments. It is spatially abstracted to an area. Entity Type: Concept.本实体描述机场跑道周边区域：该区域的片区规划中设有管控或限制特定活动的规则，此类活动可能诱使鸟类飞行活动增多，进而对航空器运行构成威胁。其几何要素通过对机场跑道进行缓冲区扩展分析，并裁剪至克赖斯特彻奇地区地方行政区域（TLA）边界生成。本实体与评级单元（RatingUnit）执行空间相交运算，以支持生成物业状况相关备注。该实体在空间上被抽象为面状区域，实体类型为概念实体（Concept）。
