Istanbul's Digital Image Replacement Efforts: A Global Comparison

Istanbul's municipal government has launched a new initiative to replace duplicate images in public databases, aiming to improve data efficiency and reduce storage costs. The project, which began in January 2026, has already replaced over 10,000 duplicate images in the city's property registration system.

The effort to eliminate duplicate images is crucial in today's digital age, where data storage and management are becoming increasingly important for urban planning and development. With the rise of digital technologies, cities like Istanbul are generating vast amounts of data, which can be difficult to manage and analyze. By removing duplicate images, the city can free up storage space and improve the accuracy of its data, ultimately leading to better decision-making and more efficient governance.

In Istanbul, the duplicate image replacement project is being implemented in various neighborhoods, including Kadikoy and Beyoglu. The Istanbul Metropolitan Municipality (IBB) is working with local organizations, such as the Istanbul Chamber of Commerce and the Turkish Informatics Foundation, to develop and implement the new system. For example, the IBB has partnered with the Turkish company, Turkcell, to develop a cloud-based storage system that can automatically detect and replace duplicate images. The system is being tested at the Istanbul Technical University's campus in Maslak, with plans to expand it to other parts of the city.

Comparing Istanbul's Approach to Other Global Cities

According to data from the Istanbul Metropolitan Municipality, the city's duplicate image replacement project has already saved over 1.5 million Turkish lira (approximately $80,000 USD) in storage costs. This is comparable to other major cities like Tokyo, which has implemented a similar project and saved over 10 million yen (approximately $90,000 USD) in storage costs. However, Istanbul's approach differs from that of New York City, which has implemented a more comprehensive data management system that includes automated data quality checks and data analytics tools. For instance, New York City's data management system has helped reduce data storage costs by 25% and improved data accuracy by 30%.

In terms of specific statistics, Istanbul's duplicate image replacement project has replaced an average of 500 duplicate images per day, with a total of 15,000 images replaced since the project began. The project is expected to be completed by the end of 2026, with a total estimated cost of 5 million Turkish lira (approximately $270,000 USD). The IBB plans to use the saved storage space to implement new data analytics tools, which will help improve urban planning and development in the city. For example, the IBB plans to use data analytics to optimize traffic flow in congested areas like the Bosphorus Bridge and to improve waste management in neighborhoods like Sisli.

As the city continues to develop and implement its duplicate image replacement project, residents and businesses can expect to see improvements in data efficiency and governance. The project is a step towards making Istanbul a more digitally savvy and efficient city, and its success will be closely watched by other major metropolitan areas around the world. The IBB plans to share its experience and best practices with other cities, including through international partnerships and conferences, such as the upcoming Smart Cities Conference in Barcelona.
