A second national 3D mapping beneath it, launched in 2019, took eight months
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
VentureBeat reports that the first 3D map was completed in 2014 and that a second mapping effort launched in 2019 cut the capture timeline to eight months.
Caveat
The article could not be retrieved for this check (the site blocks automated reads); the date rests on our earlier reading.

Sources carrying this claim

  1. VentureBeat — How Singapore created the first country-scale digital twin (2022)
Claim 10 clm-cf8eeef7fe15c7d8 quantitative
a public 3D map arrived in 2021 as SLA's separate OneMap3D

Sources carrying this claim

  1. Ministry of Law — speech at the official launch of OneMap3D (2021)
Claim 11 clm-5b068f2a44d1cb70 descriptive
The promised public access to Virtual Singapore itself never launched
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
GovTech's 2017 promise of progressive public access is the baseline; no later source records it happening.
Caveat
An absence: established by the lack of any later announcement, not by a single statement.

Sources carrying this claim

  1. GovTech Singapore — 5 things to know about Virtual Singapore (official, 2017)
Claim 12 clm-a8acbba9cebbf2f4 descriptive
the name has since disappeared from government programme pages
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
Singapore's 2025 digital-twin announcement frames the work under the Geospatial Master Plan without naming Virtual Singapore.
Caveat
An absence: no quotable sentence carries it; the original 2014 SLA press release now returns 'Page not found'.

Sources carrying this claim

  1. Maritime and Port Authority of Singapore — Maritime Digital Twin launch (2025)
Claim 13 clm-37e3b0ffdfe06707 quantitative

Published field
impact · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
VentureBeat reports the aerial capture figures.
Caveat
A widely circulated variant misreads this as '160,000 buildings' — the figure counts aerial images. The article could not be retrieved for this check.

Sources carrying this claim

  1. VentureBeat — How Singapore created the first country-scale digital twin (2022)
Claim 15 clm-037052c47cff7e99 descriptive

Published field
impact · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
The article states the five-year and two-year cycles.

  1. GIM International — Singapore's journey towards a nationwide digital twin (with SLA's Land Survey Division, 2022)
Claim 16 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 file
What the mapping says
Its results section lists what decision-makers can do, not what they did.
Caveat

Published field
body · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
The US trade-press account dates the launch to the end of 2014 under the Smart Nation drive; no listed source carries an exact day.
Caveat
No claim-specific caveat recorded

In 2015, Dassault Systèmes signed on to build the platform on its 3DEXPERIENCity software
Published field
body · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
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.
Caveat
No claim-specific caveat recorded

Sources carrying this claim

  1. Dassault Systèmes — investor press release on the NRF collaboration (vendor, 2015)
Claim 21 clm-8ab98527dd132b4c quantitative

Published field
body · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
The 2018 Reuters wire story is the source of nearly all international coverage, including the 'planners and plotters' framing and the security concern.
Caveat
No claim-specific caveat recorded

Sources carrying this claim

  1. Reuters (via Euronews) — Virtual Singapore project could be test bed for planners – and plotters (2018)
Claim 22 clm-97d702ba4e260f5d descriptive

mapped · no interpretation or interpolation added by this file
What the mapping says
govtech.com describes the Yuhua exercise, in an older estate identified for green upgrades, and quotes GovTech's geospatial lead on modelling the installed panels against energy-bill data.
Caveat

  1. Government Technology (govtech.com) — Virtual Singapore Is More Than Just a 3-D Model (US trade press, ~2017)
Claim 24 clm-f29fd43deba48da2 descriptive
The NRF's Virtual Singapore programme page is gone; so is the Smart Nation initiative page
Published field
body · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
The atlas's own check (September 2026): neither the NRF programme page nor the Smart Nation initiative page resolves, and SLA's 2014 announcement is also offline. No cancellation notice or closing report was found in any source.
Caveat
No claim-specific caveat recorded

Published field
body · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
JTC's own page (revised January 2026) describes the Open Digital Platform, with district-wide IoT sensors for estate staff — a separate system from Virtual Singapore.
