Istanbul's Duplicate Image Problem: What Officials, Experts and Key Figures Are Saying

A growing headache inside Istanbul's municipal government has surfaced in public: duplicate and misattributed images embedded in official digital communications, heritage records, and urban planning documents are undermining credibility and creating legal exposure. The Istanbul Metropolitan Municipality, which operates one of the largest civic digital archives in Turkey, has been contending with the problem for months, and voices from the technology, legal, and heritage sectors are now weighing in with competing prescriptions.

The issue has sharpened this spring as the municipality accelerated its digitisation push under its Smart Istanbul platform — a program that spans everything from traffic monitoring to the cataloguing of historical structures across the Fatih and Beyoğlu districts. When images sourced from multiple contractors end up duplicated or mislabelled in public-facing portals, the consequences range from bureaucratic embarrassment to copyright liability under Turkish intellectual property law.

Where the Problem Is Most Visible

Two institutions sit at the centre of current concern. The İstanbul Planlama Ajansı — the Istanbul Planning Agency, or İPA, which produces research and policy documents for the Metropolitan Municipality — has flagged internal workflow gaps in how visual assets are tagged and stored across departments. Separately, the Atatürk Kitaplığı on Millet Caddesi in Beyoğlu, one of Istanbul's principal public research libraries and a custodian of historical photograph collections, has been working with consultants to audit digitised image sets that were transferred from analogue archives between 2019 and 2023.

Technology specialists familiar with public-sector digital asset management say the core problem is structural rather than accidental. Without a unified metadata standard and a single-source image repository, different departments independently upload versions of the same photograph or rendering, sometimes with different copyright annotations. The result is a database riddled with redundancy — and documents published online that carry images whose provenance cannot be quickly verified.

Legal practitioners in Istanbul's intellectual property community have pointed to real financial risk. Under Turkey's Law on Intellectual and Artistic Works — Law No. 5846 — the unauthorised reproduction or misattribution of a protected image can expose a public body to civil damages claims. Procurement records show the Metropolitan Municipality signed at least three separate contracts with digital services firms in 2024 and 2025, each covering some aspect of content management, but observers note the contracts did not appear to establish a shared image governance standard across all departments.

What Experts and Sector Figures Are Recommending

The debate has attracted voices from Istanbul Technical University's informatics faculty, heritage preservation NGOs active in Karaköy and Balat, and private technology consultants who work with Turkish public institutions. The consensus prescription involves three components: a centralised digital asset management system with hash-based duplicate detection, mandatory IPTC metadata standards for all new uploads, and a retroactive audit of legacy image libraries before the end of 2026.

Practitioners note that comparable exercises in cities like Amsterdam and Barcelona took between 18 months and three years to complete for archives of similar scale — and both required dedicated budget lines that were approved at the political level, not left to IT departments alone. Istanbul's digital archive, covering everything from Bosphorus shoreline planning renders to documentation of buildings in the earthquake-risk zones identified after the February 2023 Kahramanmaraş disaster, is estimated by sector analysts to contain several million individual image files across fragmented storage systems.

The timing matters because Istanbul is preparing a major update to its urban transformation data portal ahead of local budget negotiations in late 2026. If the duplicate image problem is not resolved before that portal goes live, inaccurate or redundant visuals attached to earthquake-risk assessments or heritage zone maps could feed into decisions with serious public safety and legal implications.

For now, the practical advice circulating among municipal IT staff and their outside advisers is consistent: freeze new bulk uploads until a deduplication protocol is in place, establish a single point of editorial control for all publicly published images, and bring copyright clearance checks into the procurement stage rather than treating them as an afterthought. Whether the political bandwidth exists to fund and prioritise that work, with the Metropolitan Municipality already navigating strained relations with the central government in Ankara, is the question no one in the sector is prepared to answer definitively just yet.
