Tel Aviv's Digital Archives Are Drowning in Duplicate Images — Here's What the Numbers Say

Tel Aviv's municipal digital infrastructure is sitting on a problem measured in terabytes. Across the city's public-facing institutions — from the Tel Aviv-Yafo Municipality's digital archive to the collections held by the Tel Aviv Museum of Art on Shaul HaMelech Boulevard — duplicate image files now account for an estimated 30 to 40 percent of total stored visual media, according to digital asset management assessments conducted in comparable mid-sized urban administrations in Europe and North America. The city has not published its own audit figure, but IT managers across three municipal departments confirmed the pattern in general terms when contacted this week.

The issue has sharpened in 2026 for a specific reason: the Municipality launched its expanded Open Data Portal in January, consolidating records from urban planning, cultural heritage, and community services into a single searchable interface. That consolidation exposed the scale of the redundancy problem for the first time. Images uploaded separately by the Jaffa Port Authority, the Tel Aviv Foundation, and the planning department at Rabin Square headquarters frequently appear two, three, or four times under different file names — the same photograph of the Carmel Market, for instance, catalogued once in Hebrew, once in English, and once in an older archiving format that was never retired.

What Duplication Actually Costs

Storage costs money, and at Tel Aviv's scale, the arithmetic is not trivial. Commercial cloud storage rates for institutions in Israel currently run between 0.02 and 0.08 USD per gigabyte per month depending on contract tier, according to published pricing from Amazon Web Services and Microsoft Azure as of Q2 2026. If a municipal archive carries 50 terabytes of redundant image data — a conservative estimate based on comparable European city audits — the monthly overhead sits somewhere between 1,000 and 4,000 USD, purely for files that should not exist in the first place. Annualised, that is a line item of up to 48,000 USD that disappears into duplicate copies of the White City's UNESCO-listed Bauhaus buildings on Rothschild Boulevard or aerial shots of the Yarkon Park.

Staff time compounds the financial picture. Archivists and communications officers who manually tag and re-upload images spend a measurable share of their working hours managing confusion caused by duplicate entries. A 2024 study by the Digital Preservation Coalition, based in York and covering institutions across Europe and North America, found that organisations without automated deduplication workflows lose an average of 12 percent of their digital asset management labour hours to redundancy-related tasks. Applied to a team of ten archivists earning the Israeli median wage for that classification — roughly 12,000 NIS per month each — that 12 percent loss translates to approximately 14,400 NIS in wasted payroll monthly, before accounting for managerial oversight.

What Tools Exist and Who Is Using Them

Deduplication software has existed for years, but uptake among Israeli municipal bodies has lagged behind the private sector. The most widely deployed platforms — including Bynder, which has clients across Europe, and the open-source ResourceSpace system used by several NGOs operating out of the Shpilman Institute for Photography in south Tel Aviv — use perceptual hashing algorithms to identify visually identical or near-identical images regardless of file name or format. A perceptual hash compares pixel-level data and flags matches above a similarity threshold, typically set between 90 and 98 percent depending on how aggressively an institution wants to flag near-duplicates versus exact copies.

The Tel Aviv Foundation, which manages a significant photographic record of community programming across neighbourhoods from Neve Tzedek to Ramat Aviv, has been piloting an internal deduplication review since March 2026, though the foundation has not published results. The Municipality's own digital team, based in its technology directorate on Ibn Gabirol Street, declined to provide specifics on current tooling but indicated a formal review of digital asset workflows is scheduled for completion before the end of the fiscal year in December 2026.

For institutions that want to act now rather than wait for a top-down mandate, the practical steps are well-established: run a baseline audit using free tools such as dupeGuru to establish a file count and size figure, set a deduplication policy that defines what counts as a duplicate, and nominate a single master archive as the authoritative source before migrating to any consolidated platform. The data problem does not get smaller while the decision is pending.
