The problem
The question is no longer only about data precision.
In mapping, construction, infrastructure and digital territory projects, geospatial data is not just a technical deliverable. It is evidence for decisions, investment justification, disputes and regulatory compliance.
How do you know this dataset is authentic, intact and has not been altered since capture?
Doubts whether the deliverable matches the original capture.
Without objective evidence, trust depends on the provider or manual documentation.
Claims about dates, parameters or real site conditions.
Contract disputes where a verifiable capture and delivery history is missing.
Digital manipulation risk in the generative AI era.
Harder to distinguish physically captured data from altered or synthetic content.
Before and after
From technical files to verifiable evidence.
Before
With Obliquo Certify
Heavy files with no integrity proof.
Cryptographic fingerprint per dataset or event.
Duplicate versions in folders and deliveries.
Structured manifest with technical metadata.
Trust based on provider or manual documentation.
Verifiable timestamp.
Hard to prove dates, origin and changes.
Digital chain of custody.
Technical disputes with little objective evidence.
Independent evidence for audits, clients or legal processes.
How it works
Verifiable certification without moving heavy data to blockchain.
Obliquo Certify integrates into capture, processing, publishing and delivery. It certifies relevant events without breaking your technical workflows.
01
Capture or event
Flight, scan, processing, delivery or update.
02
Cryptographic fingerprint
A SHA-256 hash is generated for the dataset or manifest.
03
Structured manifest
Includes project, date, bounding box, sensor, technical parameters, operator, version and hash.
04
Verifiable record
The manifest hash is registered with a timestamp for independent verification.
If the dataset changes, its fingerprint changes. The discrepancy is detectable.
When certification is worth it
No when:
- it is internal visualization with no external impact
- there are no third parties or obligations
- the data is not reused
- you only need to store files
Yes when:
- the data may end up in an audit
- there is a contract, tender or claim
- several parties depend on the same dataset
- the dataset is reused or licensed
- there is manipulation or dispute risk

Why Certify
Not storage. Not just visualization. Verifiable trust.
Does not store heavy data on blockchain
Only cryptographic fingerprints are registered. Efficient, scalable and viable for large geospatial datasets.
Independent verification
Integrity can be checked without relying solely on a private database.
Digital chain of custody
Records capture, processing, delivery, updates and reuse.
Ready for generative AI
Helps distinguish captured, processed and certified data from altered or synthetic content.
Trusted Reality Platform
Platforms process, visualise and publish data. Obliquo Certify certifies reality.
Technical model
The trust layer on your geospatial infrastructure.
Your data stays where it already is. Certify adds integrity, manifest and verification without replacing your tools.

FAQ
Answers before certifying your datasets
Integrity, traceability and verifiable evidence without moving heavy data to blockchain.
Is data stored on blockchain?
No. Heavy data stays in your usual infrastructure. Obliquo Certify registers cryptographic fingerprints and verifiable metadata.
What happens if the dataset changes?
Any change produces a different fingerprint. That makes discrepancies against the certified dataset detectable.
Which events can I certify?
Capture, processing, delivery, updates, versioning, reuse or any relevant event in the data lifecycle.
Is it suitable for public tenders?
It can be incorporated as an objective technical improvement where integrity, traceability, transparency and audit matter.
Does it replace my current tools?
No. It integrates on top of your capture, processing, storage and publishing workflows.
Which data types are supported?
Photogrammetry RAW, orthophotos, DSM/DTM, LiDAR point clouds, 3D models, meshes, IFC, 3D Tiles, GeoJSON and other geospatial assets.
Who can verify the certification?
Clients, public bodies, auditors, experts or authorised third parties via certificate, web verifier or API.
Is it designed for generative AI?
Yes. It helps demonstrate which data was physically captured, when, where and under which technical conditions.
