A working decision rehearsal
- Deterministic matched non-EO and EO comparison
- Strict evidence, provenance and refusal contracts
- Downloadable public-safe synthetic record
URBAN ECOTOPIA · SITE HEAT EVIDENCE REVIEW
For London development and estate teams with one authorised site and one live decision. Compare historic Earth observation and site context through a bounded, traceable evidence workflow before commissioning more detailed investigation.
WORKING SYNTHETIC PROOF · LIVE PILOT EVIDENCE OPEN · LONDON

The geography, options, reviewer and permitted use are declared before analysis begins.
A PUBLIC CLAIM LEDGER
Local engineering evidence can demonstrate a controlled workflow. Only an authorised site, retained customer response and independent review can establish real-world value.
LOCAL VALIDATION IS NOT CUSTOMER, SCIENTIFIC, LEGAL OR GRANT VALIDATION
THE QUESTION AFTER SCREENING
A heat map can show a pattern. The service is designed to compare a limited set of tree, shade, cool-roof and surface options, then explain why a priority changed and where the evidence may fail.
OBSERVATION · PHYSICS · MODELLING · REVIEW
Observed, derived, modelled and reviewed information never collapse into one opaque score. Each hand-off retains its state, source and authority.
Historic surface signals with date, coverage and source rights.
Physical form, street topology, canopy, surface and social context.
Explicit input changes compared at the same site and spatial support.
Lineage, uncertainty, validation state and applicability remain attached.
An accountable reviewer may release, narrow or stop the analysis.
A RETAINED DECISION RECORD
Each candidate priority arrives with the evidence needed to inspect it and the limits needed to challenge it. No dashboard screenshot is treated as a decision record.
