Singapore Takes Aim at Duplicate Images in Public Records — and It's Moving Faster Than London or Tokyo

Singapore's Urban Redevelopment Authority began a systematic audit of duplicate images across its GeoSpace public mapping platform in January 2026, targeting tens of thousands of redundant property photographs and planning document scans accumulated since the portal launched in 2014. The cleanup is the most aggressive of its kind attempted by any city-state registry in Southeast Asia.

The issue sounds mundane until you look at what it actually costs. Duplicate image records inflate storage infrastructure bills, slow down database queries for professionals pulling planning approvals on sites from Jurong East to Tampines, and introduce version-control errors that have caused delays in development applications. For a government that has staked considerable political capital on positioning Singapore as a precision-run digital economy, redundant data is not a trivial housekeeping matter.

Why Now, and Why It Matters Beyond IT

The timing is not accidental. The Smart Nation and Digital Government Office has been pushing agencies to meet a data hygiene benchmark ahead of a broader government cloud migration scheduled for completion by the end of 2027. Duplicate images — particularly in the HDB's MyHDBPage resale portal and the SLA's OneMap cadastral database — were flagged as a specific bottleneck in an inter-agency review completed in late 2025. Property agents working out of offices along Toa Payoh Lorong 6 and in the Raffles Place financial district have long complained that searching resale flat records sometimes surfaces the same exterior photograph three or four times under different submission timestamps, making due-diligence checks slower than they should be.

Compare that with London, where the Greater London Authority's planning portal, Planning London Datahub, acknowledged a similar backlog of redundant planning images in a 2024 transparency report but has yet to announce a structured deduplication timeline. Tokyo's Land and Infrastructure Ministry began a pilot deduplication exercise covering the Shinjuku ward records in March 2025, but the effort remains limited to one of the city's 23 special wards. Singapore's URA initiative, by contrast, is being run government-wide, covering records held by at least six agencies simultaneously.

Seoul's Ministry of Land, Infrastructure and Transport rolled out an AI-assisted deduplication tool across its public real estate information system in 2023, and that remains the most advanced comparable deployment in the region. Singapore's GovTech is understood to be benchmarking against Seoul's model, though officials have not publicly confirmed which vendor or methodology is being adopted for the current URA exercise.

What the Data Actually Shows

According to figures published in the Smart Nation 2025 Annual Report, Singapore's whole-of-government data estate held approximately 4.2 petabytes of unstructured data as of December 2024, of which image files constituted the single largest file-type category. The URA has not published a specific count of duplicate images identified so far, but the January audit scope covered records dating back 12 years across roughly 1.1 million property entries in the central registry.

For context, a standard high-resolution building facade photograph used in a planning submission runs between 8 and 15 megabytes. Even a conservative duplication rate of five percent across the URA's image holdings represents storage equivalent to thousands of dollars in annual cloud costs — and that is before factoring in the downstream productivity drain on the 4,800-odd licensed real estate agents who query these systems regularly.

The practical implication for Singaporeans is straightforward. Property buyers doing their own checks on HDB flats in Bukit Merah or Woodlands should expect search results on government portals to become cleaner and faster as the deduplication rolls out through the second half of 2026. Conveyancing lawyers and valuers who rely on OneMap overlays for mortgage submissions should see fewer duplicate image returns by the fourth quarter.

GovTech has indicated it will publish interim findings from the audit before the end of September 2026. Whether those findings include a replicable framework that other cities can adopt will determine whether Singapore ends up leading a regional standard — or simply cleaning its own house quietly, ahead of schedule, as it usually does.
