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 for escalation.
• Follow ../security.md for geolocation data protection controls.
• Use ../troubleshooting.md 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.
