# Geospatial Search
|
|
|
|
## Purpose And Business Outcome
|
|
|
|
Support location-aware queries such as nearest-neighbor and bounding-box lookups for geospatial workloads.
|
|
|
|
## Scope And Non-Goals
|
|
|
|
Scope:
|
|
- Spatial index configuration
|
|
- Proximity and bounding-box query operations
|
|
|
|
Non-goals:
|
|
- Full GIS projection transformations
|
|
- External map tile services
|
|
|
|
## User And System Workflows
|
|
|
|
1. Consumer configures spatial index for coordinate fields.
|
|
2. Coordinates are serialized and stored with entity payloads.
|
|
3. Query path evaluates `Near` or `Within` predicates.
|
|
4. Engine returns matching entities.
|
|
|
|
## Interfaces And APIs
|
|
|
|
- Spatial index APIs in model configuration
|
|
- Query helpers under `GeoSpatialExtensions`
|
|
- Index implementation in `RTreeIndex`
|
|
|
|
## Permissions And Data Handling
|
|
|
|
- Geolocation data may be regulated or privacy-sensitive.
|
|
- Apply least-privilege access and retention limits.
|
|
|
|
## Dependencies And Failure Modes
|
|
|
|
Dependencies:
|
|
- Correct coordinate format and units
|
|
- Spatial index consistency
|
|
|
|
Failure modes:
|
|
- Invalid coordinate values
|
|
- Unexpected results from bounding definitions or radius units
|
|
|
|
## Monitoring, Alerts, And Troubleshooting
|
|
|
|
- Validate geospatial paths through dedicated stress and correctness tests.
|
|
- Use [`../runbook.md`](../runbook.md) for escalation.
|
|
- Follow [`../security.md`](../security.md) for geolocation data protection controls.
|
|
- Use [`../troubleshooting.md`](../troubleshooting.md#query-and-index-issues) for issue resolution.
|
|
|
|
## Rollout And Change Considerations
|
|
|
|
- Document coordinate and unit assumptions in release notes when behavior changes.
|
|
- Validate backward compatibility for persisted spatial index pages.
|
|
|
|
## Validation Guidance
|
|
|
|
- Run `GeospatialTests` and `GeospatialStressTests` before release.
|
|
- Include representative proximity/bounding queries in smoke checks.
