Ho Chi Minh City's Digital Archives Plagued by Thousands of Ghost Images

City planners and property developers operating in Ho Chi Minh City's District 1 and Binh Thanh have spent the better part of 2025 and early 2026 wrestling with a specific, unglamorous problem: duplicate image files embedded in official land-use certificates, environmental impact assessments, and zoning visualisation portals have been quietly corrupting digital records, slowing permit approvals, and causing mismatches between what buyers see online and what actually exists on the ground. The problem did not appear overnight. It is the product of roughly a decade of decisions that now demand a systematic fix.

The timing matters because Vietnam's real estate market, after a sharp correction that ran through much of 2023 and 2024, is again attracting serious foreign direct investment. The Ho Chi Minh City Department of Natural Resources and Environment, which manages the city's land registration portal, has been under pressure to modernise its document-handling infrastructure ahead of a broader national push under the government's National Digital Transformation Program, which set 2025 as a benchmark year for migrating core public services online. Broken or duplicated imagery inside official documents is not a cosmetic issue when a deed transfer or a construction licence hangs on the file.

A Problem Built Layer by Layer

The roots trace to 2016, when Ho Chi Minh City launched an early phase of its Smart City initiative and began scanning physical planning documents at pace. Individual district-level offices, from the District 7 Urban Management Division to the Thu Duc City Administrative Centre, which became a separate administrative unit in 2021, each maintained their own image repositories. There was no single master standard for file naming, resolution, or format. A cadastral map scanned in District 7 could carry the same internal file identifier as an architectural rendering uploaded by a developer in Binh Duong under a joint submission, producing collisions when the records were eventually merged into the Ho Chi Minh City GIS portal.

The construction boom made it worse. Between 2018 and 2022, approved building permits in the city ran into the tens of thousands annually, each submission package carrying multiple image attachments. When developers resubmitted revised plans, common during the extended approval cycles that characterised that period, the earlier image versions frequently remained in the system rather than being replaced, creating duplicate layers inside the same project file. Staff at the One-Stop-Shop service counters on Le Thanh Ton Street in District 1 were flagging the problem in internal memos by late 2020, but a coordinated technical response did not materialise before the COVID-19 disruptions reshaped administrative priorities entirely.

Where Things Stand in Mid-2026

The Ho Chi Minh City Department of Information and Communications, working alongside the municipal e-government office on Nguyen Thi Minh Khai Street, formally identified duplicate image replacement as a technical priority item in the second quarter of 2026. The work involves running deduplication scripts against the city's property and planning databases, establishing a unified image hash registry so that future uploads can be checked against existing files in real time, and retraining document management staff across all 22 districts and Thu Duc City.

The practical stakes are visible at ground level. Real estate agencies operating along Nguyen Huu Canh Street in Binh Thanh, an area that has seen steady condominium development, have reported instances where online property listings pulled images from the wrong cadastral record, showing plot boundaries that no longer reflected post-subdivision reality. For buyers navigating a market where average transaction prices for mid-range apartments in Thu Duc City hovered around 45 million VND per square metre in the first quarter of 2026, that kind of documentation error carries real financial risk.

For developers, lawyers, and individual buyers dealing with city records right now, the practical advice is straightforward: request a freshly generated PDF export of any land-use certificate or planning document rather than relying on a cached version, and cross-check image references against the physical cadastral map held at the relevant district-level land registration office. The deduplication work is ongoing, and until a completion date is formally announced, the safest assumption is that any document pulled from the portal before July 2026 may contain legacy image data that has not yet been audited.
