+## Work Log - 高程数据集支持删除（2026-05-03）
+
+- 背景：
+ - Issue `FL-180` 需要“高程数据集支持删除”。
+ - 现有高程管理仅支持创建/更新/分析/预览，缺少删除闭环。
+
+- 本次改动：
+ - 后端新增数据集删除能力：
+ - 文件：`api/app/services/elevation_service.py`
+ - 新增 `delete_dataset(db, dataset_id)`：
+ - 数据集不存在返回 `False`；
+ - 存在运行中回填任务时返回 `409`，避免删除过程中任务写入异常；
+ - 删除前先清理关联 `elevation_apply_job` 记录，再删除数据集；
+ - 发布 `elevation.dataset.deleted` 主题事件，触发前端数据刷新。
+ - 后端新增删除接口：
+ - 文件：`api/app/api/v1/elevation.py`
+ - 新增 `DELETE /api/v1/elevation/datasets/{dataset_id}`（权限：`elevation.manage`）。
+ - 前端高程管理页新增删除入口：
+ - 文件：`web/src/app/admin/elevation/page.tsx`
+ - 数据集操作列新增“删除”；
+ - 使用 `App.useApp().modal.confirm` 二次确认；
+ - 删除成功后提示并刷新数据集/任务列表，同时清理预览弹窗状态。
+
+- 风险与影响：
+ - 删除数据集会同时删除其关联的回填任务记录（仅记录，不会回滚已写入杆塔的高程值）。
+ - 若数据集存在运行中任务，接口会拒绝删除并提示先等待任务结束。
+
