Claims, one by one

The text below is copied verbatim from the published record. Each claim names the source dossiers that carry it; caveats stay attached to the claim they qualify.

Claim 1 clm-37e3b0ffdfe06707 quantitative
captured over 160,000 high-resolution aerial images in 41 days for a nationwide 0.1-metre reality mesh
Published field
impact · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
VentureBeat (23 Feb 2022): 'The SLA captured over 160,000 high-res aerial images over forty-one days, and Bentley's ContextCapture tools worked to transform these into a 0.1-meter accurate nationwide 3D reality mesh.'
Caveat
A widely circulated variant misreads this as '160,000 buildings' — the figure counts aerial images. Article sits behind a bot wall; verify via the archived copy.

Sources carrying this claim

  1. VentureBeat — How Singapore created the first country-scale digital twin (2022)
Claim 2 clm-36eeabc4fae78a81 quantitative
roughly 25 TB of street data from 600 billion point-cloud points and 3 million panoramic images
Published field
impact · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
GIM International (24 Aug 2022, co-authored by SLA's Land Survey Division): '600 billion point clouds and three million panoramic images … approximately 25TB of data.'
Caveat
No claim-specific caveat recorded

Sources carrying this claim

  1. GIM International — Singapore's journey towards a nationwide digital twin (SLA authors, 2022)
Claim 3 clm-037052c47cff7e99 descriptive
refreshed every five years by air and every two years at street level
Published field
impact · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
Same SLA-authored article: the plan is to 'map the whole nation once every five years using aerial mapping, and to refresh the street mobile mapping data every two years'.
Caveat
Stated as the plan in 2022; no later source confirms the cycle has been kept.

  1. GIM International — Singapore's journey towards a nationwide digital twin (SLA authors, 2022)
Claim 4 clm-484eead4348af846 quantitative
the OECD's 2024 case study describes capabilities only
Published field
impact · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The OPSI entry (updated 5 Nov 2024) frames every application in the possibility mood — 'decision-makers can optimise land use, assess flood risk, and manage underground utilities more effectively' — and contains no documented decision, adoption figure or outcome number.
Caveat
Negative claim: verified by reading the case study in full, not by a single quotable sentence.

Sources carrying this claim

  1. OECD Observatory of Public Sector Innovation — Virtual Twin Singapore (independent, updated Nov 2024)
Claim 5 clm-6ffe39cf774c1670 descriptive
when Singapore needed twins that actually run something, it built new platforms — Punggol's sensor-fed Open Digital Platform and the port's Maritime Digital Twin
Published field
lesson · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
JTC describes the Punggol ODP as 'completely operationalized, a virtual 3D environment fed live data mined from the sensors of the physical facility management systems'; MPA launched 'its first Maritime Digital Twin on 24 March 2025 – a virtual model of Singapore's port'. Neither is built on Virtual Singapore.

Published field
body · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
Dassault Systemes' 2015 investor press release announces the collaboration and the 3DEXPERIENCity platform. Used for the fact of the contract only, never for a capability claim.

Published field

Known limits of this passport
  • Publisher names and source languages have not yet been classified; domains are recorded without guessing.
  • Existing source notes are descriptive locators, not page- or paragraph-exact citations.
  • A missing archive, publication date or content hash is shown as null rather than inferred.
  • The project-level evidence grade ranks the strongest source in the entry; it is not a truth score for every claim.
