What can satellite observations add to a real-estate collateral review?
Satellite observations can help a reviewer identify visible changes around a defined property and decide which supporting records to request. They do not establish market value, legal status or technical condition on their own. The intended CRI workflow links each observation to its date, source, uncertainty and review context so that the institution can assess its relevance.
The public Evidence Pack and The Brief present prepared examples. The CRI demonstrator is in development. The functions available in a demonstration and the scope of any paid engagement are agreed separately. Specialist review remains part of the process.

What has changed since the previous review?
In a portfolio review, an earlier record describes a property and its surroundings, while a later observation shows a different visible surface pattern near it. Before assigning significance, the reviewer needs to establish where the change is, whether it concerns the monitored asset and what the earlier record actually covered.
The useful follow-up is a defined question for a document owner, valuer or technical adviser. A change near an asset may turn out to be outside the relevant boundary or unrelated to the purpose of the review.
Connect the observation to the right property
Asset identity and boundary: use the institution’s property reference and verified spatial scope. An image tile is not a property-title record.
Baseline: retain the previous review date, the documents used and any unresolved questions.
Dated observations: check coverage and comparability before interpreting a difference.
Review purpose: state why the potential change matters to this review and who can assess that relationship.
Portfolio scale does not remove the need to check individual evidence quality. A missing observation and a visible change are different evidence states and may require different follow-up.
An example of a focused follow-up
Review question: Does the changed visible surface fall within the monitored property or a relevant access area, and which dated record explains it?
Check the observation area against the institution-confirmed boundary and identify the dates being compared.
Ask for the relevant current plan, project explanation or technical report; check that it covers the same area and period.
Record what the reply resolves, what remains uncertain and whether a site visit or specialist assessment is needed.
This scenario is a proposed review process, not an assessment of a named property. No property price, loan-to-value ratio or credit-risk score is calculated from the imagery.
Observed change, uncertainty and risk remain distinct
A visible difference is an observation to interpret in context. Insufficient coverage means the question remains open. Neither is automatically a negative risk finding. An unchanged-looking surface also cannot rule out hidden deterioration or changes in legal or financial circumstances.
Market value, ownership, encumbrances and technical condition require other records and appropriate professional assessment. The institution retains its existing valuation, inspection and risk processes. CRI is being developed to support the preparation and traceability of the evidence considered in those processes.
