+# SBAS-InSAR 点矢量导出与多监测点曲线设计
+
+## 背景
+
+当前 Gamma SBAS 专家路径已经产出 LOS 形变速率、LOS sigma、RGB 预览和单个自动监测点曲线。论文和报告中常见的表达方式不是只展示一个自动点，而是以 LOS 速率栅格为主图，并配合若干代表点的时序曲线、质量图和统计说明。
+
+专家文档第十二步“结果输出、地理编码与点位时序”给出的标准路径包括：
+
+- `ts_rate` 计算平均形变速率；
+- `rasdt_pwr` 生成速率预览图；
+- `geocode_back` 地理编码速率结果；
+- `data2geotiff` 输出 GeoTIFF；
+- `disp_prt_2d` 根据 `disp_point.txt` 输出点位时序。
+
+专家文档没有要求把所有有效像元直接矢量化。全量点矢量属于发布产物扩展，不改变 Gamma/SBAS 计算链路。
+
+## 目标
+
+1. 保持 GeoTIFF 作为可信主产品。
+2. 新增全量有效像元点 GeoJSON.gz，供用户下载后在 QGIS、ArcGIS、Python 或精细制图流程中使用。
+3. 前端不渲染全量点，只展示文件、点数、字段和下载入口。
+4. 默认自动监测点从 1 个扩展为多个代表点，便于结果页展示多条时序曲线。
+
+## 非目标
+
+- 不把全量点 GeoJSON 作为前端地图图层渲染。
+- 不用点矢量替代 LOS 速率 GeoTIFF。
+- 不把自动点解释为专家确认点、业务监测网或最终工程控制点。

+P3 auto_abs_high_rate_low_sigma
+P4 auto_stable_low_sigma
+P5 auto_center_valid
+```
+
+选择原则：
+
+- 排除边缘区域；
+- 只使用有效像元；
+- sigma 越低越优先；
+- 高形变点用于展示明显形变信号；
+- 稳定点用于对比；
+- 中心点用于空间代表性；
+- 点之间设置最小距离，避免扎堆。
+
+手动点：
+
+- 仍保留 `manual_lonlat` 模式；
+- 当用户或后续点位管理页面提供点位时，按手动点优先；
+- 自动点仅作为无手动点时的默认代表点。
+
+前端展示：
+
+- 保留每个点的 PNG/CSV/metadata 下载；
+- 结果页可展示多张点位曲线预览；
+- 后续再实现同一坐标轴上的多曲线叠加。
+
+## 生产链路位置
+
+点矢量和多监测点都放在专家路径第十二步之后：
+
+1. Gamma 输出速率、sigma、GeoTIFF；
+2. 生成点矢量 GeoJSON.gz；
+3. 提取多个监测点时序；
+4. catalog 自动登记产物；
+5. 前端展示下载和曲线预览。
+
+这样不会改变核心 SBAS 计算过程，只扩展发布和结果管理层。
+
+## 风险与约束
+
+- GeoJSON 体积会随范围快速增大，所以必须 gzip 压缩，前端不得加载。
+- 大范围任务后续应增加抽稀点矢量、CSV/Parquet 或 GeoPackage/FlatGeobuf 导出。
+- 自动点只适合作为快速检查和报告初稿候选点，正式报告应支持用户指定点、导入点位或专家确认点位。

+# SBAS-InSAR 序列发现与 AOI 选栈设计
+
+## 现状结论
+
+当前系统不是限制最多 7 景。对 `D:\LuTan1_Image_Pool` 的检查结果为：
+
+- LT1 场景目录：1500 个；
+- 按当前严格规则分组后：886 个候选序列；
+- 最大可用序列：7 个日期。
+
+当前发现逻辑的硬分组键为：
+
+```text
+satellite
+satellite_mode
+receiving_station
+relative_orbit
+orbit_direction
+imaging_mode
+polarization
+center_bucket
+```
+
+其中 `center_bucket` 约为 0.1 度经纬度格网。这个规则保守、容易复现，但它不是标准 SBAS 选栈方法。它会把相邻 frame、中心点略有偏移但实际覆盖同一 AOI 的影像拆成不同序列。
+
+## 一般 SBAS 选序列方法
+
+SBAS 序列选择通常不是先按影像中心点硬分组，而是围绕一个目标区域 AOI 建栈：
+
+1. 选择目标区域  
+   AOI 可以是行政区、工程区、多边形、bbox、中心点缓冲区或已有项目范围。
+
+2. 选择同一观测几何  
+   一般要求同一轨道方向、同一相对轨道、同一成像模式、同一极化、相近视角和足够 footprint 重叠。  
+   对 LT1 当前实现，默认仍应保持 LT1A/LT1B 分开；跨星合并只能作为高级实验模式。
+
+3. 按 AOI 覆盖筛选影像  
+   影像 footprint 需要覆盖 AOI，或者至少满足指定覆盖比例。最终处理范围通常取所有入选影像的公共交集。
+
+4. 检查时间密度  
+   关注日期数量、最大时间间隔、季节性断档、时间跨度。SBAS 越密越好，但必须保证网络连通。
+
+5. 检查轨道和 DEM 可用性  
+   精轨缺失的影像可先展示，但默认不进入可生产栈。
+
+6. 构建小基线网络  
+   不是简单相邻配对。常见做法是根据时间基线和垂直基线构图，选择满足阈值的边，并保证图连通。
+
+7. 用处理引擎验证基线  
+   真实垂直基线应由 Gamma `base_calc` 或等价步骤计算。元数据阶段只能做预筛选，不能替代最终 baseline audit。
+
+## 专家文档关系
+
+专家文档没有写自动“找序列”算法，它假设用户已经准备好 `RAW/<date>/` 数据，并在运行前手动修改日期、阈值、宽高和种子点等参数。
+
+文档中的 `base_calc` 小基线阈值示例类似：
+
+```text
+spatial baseline: -1000 1000
+temporal baseline: 0 120
+```
+
+这说明专家链路里真正决定 SBAS 网络的是 base_calc/itab 阶段。系统需要做的是把“人工准备 RAW 日期序列”产品化成可审查的 AOI 选栈和网络计划。
+
+## 设计目标
+
+1. 保留当前严格模式，作为快速、保守、可复现实验路径。
+2. 增加 AOI 发现模式，按行政区/AOI 查找覆盖同一目标区域的影像。
+3. 把 `center_bucket` 从用户可见的生产条件降级为内部诊断字段。
+4. 把接收站从硬条件降级为软提示，除非后续实测证明必须拆分。
+5. 在创建 Run 前只展示用户需要判断的生产信息：时间范围、景数、覆盖质量、网络质量和风险标签。
+6. 生成可审查的 Stack Manifest v2 和 Pair Network Plan，再交给 Gamma baseline audit 验证。
+
+## 发现模式
+
+### 1. Strict 模式
+
+当前模式，继续保留。
+
+适用场景：
+
+- 快速测试；
+- 已经验证能跑通的固定栈；
+- 用户希望尽量避免覆盖差异和几何风险。
+
+硬分组字段：
+
+```text
+satellite
+relative_orbit
+orbit_direction
+imaging_mode
+polarization
+center_bucket
+```
+
+`receiving_station` 建议改为默认软字段，不再强拆。
+
+### 2. AOI 模式
+
+新推荐模式。
+
+输入：
+
+```text
+admin_region
+bbox
+geojson polygon
+center + radius
+```
+
+处理：
+
+1. 找到所有 footprint 与 AOI 相交的 LT1 场景；
+2. 按观测几何分组；
+3. 计算每景 AOI 覆盖比例；
+4. 过滤覆盖比例不足的影像；
+5. 计算公共交集范围；
+6. 统计日期、时间间隔和精轨完整性；
+7. 输出候选栈。
+
+建议默认阈值：
+
+```text
+min_scenes: 5
+dev_min_scenes: 3
+min_aoi_coverage_ratio: 0.80
+min_common_overlap_ratio: 0.60
+warn_max_gap_days: 120
+hard_fail_max_gap_days: none，改为 warning
+```
+
+如果 AOI 是行政区且行政区很大，不应要求单景覆盖整个行政区。应允许用户进一步选择 bbox/工程区，或者默认用行政区中心缓冲区进行候选发现。
+
+### 3. 内部诊断
+
+诊断不是用户入口，也不作为生产模式展示。它只用于日志、运维、自检和开发排查。
+
+内部输出：
+
+```text
+raw_scene_count
+parsed_scene_count
+group_count
+top_groups_by_scene_count
+top_groups_by_date_count
+excluded_by_missing_orbit
+excluded_by_geometry
+excluded_by_aoi_coverage
+excluded_by_common_overlap
+```
+
+这些信息可以写入 manifest/log，必要时在管理员调试页查看。普通用户不需要看到“为什么只有 7 景”这类开发解释。
+
+## 小基线网络设计
+
+发现阶段只生成候选网络，最终以 Gamma `base_calc` 为准。
+
+建议流程：
+
+1. 对候选日期生成全部可能 pair；
+2. 先按时间基线过滤；
+3. 运行或计划 Gamma `base_calc` 得到真实垂直基线；
+4. 按垂直基线过滤；
+5. 检查网络连通性；
+6. 如果断开，允许加入 bridge edge，并标记为超阈值连接；
+7. 输出 `itab` 和 pair network summary；
+8. 前端要求用户审批。
+
+推荐网络策略：
+
+```text
+primary: connected small-baseline graph
+fallback: adjacent chain
+bridge: allow one or more warning edges when sparse archive causes seasonal gap
+```
+
+对当前数据尤其重要：如果严格使用 120 天时间阈值，2024-10 到 2025-05 的 224 天断档会导致网络断开。系统应显示风险，而不是静默删除后续年份。
+
+## Stack Manifest v2
+
+新增字段：
+
+```text

+aoi_source

+
+每个 pair 新增：

+perpendicular_baseline_m

+## 前端设计
+

+
+1. 生产区域选择：行政区、bbox、GeoJSON 或中心点缓冲区；
+2. 观测条件：轨道方向、相对轨道、极化、时间范围；
+3. 高级参数折叠区：覆盖阈值、最小景数、是否要求精轨完整；
+4. 候选列表显示：
+   - 日期数；
+   - 可生产景数；
+   - AOI 覆盖率；
+   - 公共交集面积；
+   - 最大时间间隔；
+   - 网络质量；
+   - 风险标签；
+   - 推荐/可生产/需确认状态。
+
+候选详情显示：
+
+```text
+日期列表
+覆盖范围摘要
+时间跨度和最大间隔
+pair network 摘要
+base_calc 审核结果
+```
+
+用户界面不展示原始分组数、center_bucket 分裂原因、解析失败目录等开发诊断。若需要追踪问题，这些信息进入后台日志或管理员自检接口。
+
+## 实施步骤
+
+### 阶段一：AOI 选栈入口
+
+- 增加 AOI discovery mode 参数；
+- 支持行政区/bbox/GeoJSON 输入；
+- 前端只显示推荐候选和风险标签。
+
+### 阶段二：场景覆盖筛选
+
+- 使用已有 LT1 bbox 元数据；
+- 用 shapely 计算 AOI 交集和覆盖率；
+- 输出 AOI candidate stack。
+
+### 阶段三：Stack Manifest v2
+
+- 记录 AOI、覆盖率、软硬分组字段；
+- 创建 Run 时冻结 v2 manifest；
+- 保持现有生产链路可读取 scenes 列表。
+
+### 阶段四：网络计划升级
+
+- 发现阶段生成候选 pair graph；
+- baseline audit 阶段用 Gamma `base_calc` 回填真实 Bperp；
+- 前端审批连通网络，而不是只审批相邻链。
+
+### 阶段五：生产联调
+
+- 用当前 1500 景数据池分别测试：
+  - 严格模式是否仍得到 7 景；
+  - AOI 模式是否能扩大目标区域候选；
+  - 扩大后公共交集是否仍足够；
+  - Gamma coreg/base_calc 是否接受新栈。
+
+### 阶段六：内部诊断与自检
+
+- 将严格分组统计、排除原因和解析错误写入 discovery log；
+- 管理员自检接口可查看诊断摘要；
+- 普通生产页面不展示开发诊断细节。
+
+## 风险
+
+- AOI 模式可能把相邻 frame 合进来，导致公共交集变小。
+- 跨 LT1A/LT1B 合并可能存在几何和相位一致性风险，默认不启用。
+- 接收站是否可合并需要用实测验证；先作为软字段。
+- 时间阈值过严会把稀疏数据切断，过宽会降低反演质量，需要前端显式提示。
+
+## 当前建议
+
+短期先做 AOI 模式候选发现，不要把“为什么只有几景”的开发诊断放到普通用户页面。  
+生产仍默认走可靠可审查的栈，等 AOI 候选经过 baseline audit 和一次完整 Gamma 测试后，再把 AOI 模式设为推荐入口。
+
+## 2026-05-28 实施记录
+
+本轮已把“生产区域”接入 SBAS 候选发现链路：
+
+- `/sbas-insar-production/stacks/discover` 支持 `discovery_mode=aoi`、`admin_region`、`aoi_bbox`、`min_aoi_coverage_ratio`、`min_common_overlap_ratio`；
+- 后端可把行政区名称解析成 AOI 几何，使用 LT1 元数据 bbox 与 AOI 相交关系筛选场景；
+- AOI 模式按观测几何分组，不再把 `center_bucket` 和 `receiving_station` 作为用户生产入口的硬拆分条件；
+- 候选结果新增 `discovery_mode`、`aoi`、`common_overlap_ratio`、`aoi_overlap_ratio_mean/min/max`、`hard_group_fields`、`soft_group_fields`；
+- `audit_stack` 和 `create_run` 已传递同一套 AOI 参数，确保发现、Manifest、Run 计划冻结的是同一候选序列；
+- 前端“候选 SBAS 序列发现”改为“SBAS 生产区域”，用户只输入行政区并查看日期、景数、精轨、公共重叠和覆盖摘要；
+- Run 列表不再显示 `center_bucket`，改显示行政区、平台和相对轨道。
+
+当前前端只暴露行政区入口；bbox/GeoJSON 可作为下一步高级入口接入，但不应在普通页面展示开发诊断信息。
