SPHEROID
Independent Geospatial Verification
01 Verify
Continuous Verification
Evaluate EO products and geospatial services against defined quality and operational requirements.
02 Detect
Issue Detection
Identify failed requirements, unexpected changes and deviations in delivered data and services.
03 Evidence
Verification Evidence
Preserve measurements, thresholds and verification results for investigation and reporting.
When Infrastructure Reports Success, Data Can Still Fail
EO pipelines can complete successfully while delivering incomplete, outdated or spatially inconsistent data. Infrastructure monitoring alone may not detect these issues.
System Status vs. Delivered Data
EO pipeline
System status
Delivered data
Processing
System status: Completed
Delivered data: Coverage gap
Storage
System status: Write successful
Delivered data: Empty chunk
Publication
System status: Valid metadata
Delivered data: Missing asset
Delivery
System status: HTTP 200
Delivered data: Empty response
Geospatial failures are often silent.
Services respond, dashboards stay green, and the first to notice is the end user.
How SPHEROID Integrates with Your Infrastructure
SPHEROID connects to authorised EO and GIS data sources through read-only access, without modifying production workflows or replacing existing monitoring tools.

SPHEROID agent
Read-only, scheduled, inside your environment
SPHEROID platform
Verdicts, period reports and the record of every result
Read-only Integration
No changes to production pipelines.
Controlled Access
Only authorised sources, with configurable request and volume limits.
Independent Operation
Works alongside existing monitoring and observability tools.
Verification Capabilities
- 01
Availability & Completeness
Missing assets, empty responses and incomplete products.
- 02
Spatial Consistency
Coordinate reference system, grid alignment, coverage of the area of interest, extent, resolution and NoData.
- 03
Freshness & Timeliness
Publication cadence, age of the newest data and delayed updates.
- 04
Service Behaviour
Endpoint responses, latency and the content actually returned.
- 05
Metadata & Lineage Consistency
Consistency between published metadata, referenced assets and available processing records.
- 06
Behaviour Over Time
Frozen values, step changes and deviations from each service's own history, flagged even when every individual check passes.
Use Cases
EO service providers
EO Service Assurance
Verify delivered products against quality and SLA requirements.
Multiple data sources
Multi-Provider Data Verification
Apply consistent quality checks across different providers.
Integrators and primes
System Integration & Acceptance
Independently verify delivered subsystems against acceptance criteria.
EO and GIS operators
Operational Data Quality Monitoring
Continuously track the quality of published data and services.
Built on Production Engineering Experience
SPHEROID is developed by ScaleApp, drawing on experience in building and operating production EO and geospatial systems. Named references are available on request during procurement.
