## 语义触发提示（给模型）

- 典型语义：`淤地坝分析`、`坝体识别`、`候选叠加筛选`、`结果过滤`。
- 常见上游算法依赖：
  - `geotrans_main`
  - `hydro_susceptibility`
- 常见上游数据源全称（用于检索）：
  - `2019年中国榆林市30m数字高程数据集`
  - `2019年中国榆林市沟道信息`
  - `地貌信息熵`
  - `榆林市卫星遥感数据集图像分割文件`
  - `榆林市地理坐标信息文件`

模型命中该算子后，应在数据源推荐阶段走 `synergy_datasource_search.process`，并同时使用关键词检索与全称检索。
