Bogotá Purges Thousands of Duplicate Images From Public Records

Bogotá's Secretaría Distrital de Planeación is facing a hard deadline. By September 30, 2026, the district must resolve a growing backlog of duplicate imagery embedded across multiple municipal databases, a problem that has slowed permit processing, inflated storage costs, and, in at least a handful of documented cases, caused misfiled property records in neighborhoods including Kennedy and Usaquén. The question now is who decides what gets deleted, and what legal exposure the city carries if the wrong file goes.

The issue surfaced publicly earlier this year when contractors working on the Catastro Distrital's digitization drive flagged tens of thousands of redundant image files stored across servers at the Centro Administrativo Distrital on Calle 30. The duplicates had accumulated over more than a decade of overlapping scanning campaigns, some run by the city directly, others outsourced to third-party firms under successive administrations. Auditors found that some property parcels in Fontibón had as many as seven versions of the same cadastral photograph indexed under different reference codes, tying up retrieval systems and generating conflicting ownership records.

The Stakes for Urban Planning and Property Rights

This is not a minor housekeeping exercise. Bogotá's urban development pipeline depends on clean cadastral data. The city's Plan de Ordenamiento Territorial, currently under revision for the 2026-2039 cycle, relies on accurate parcel imagery to validate zoning classifications and infrastructure investment decisions. Duplicate or mismatched files can push processing times for construction licenses beyond the 45-business-day legal limit, exposing the Secretaría de Hábitat to legal challenges from developers and individual homeowners alike.

The Instituto Distrital de Gestión de Riesgos y Cambio Climático, known as IDIGER, has a parallel stake. The agency uses georeferenced imagery from the same shared servers to map flood-risk zones along the Río Bogotá corridor and in low-lying sectors of Bosa. Corrupted or duplicated reference images have, according to internal documents reviewed by The Daily Bogotá, forced IDIGER technicians to manually verify coordinates before issuing risk certifications, a step that added an average of 11 working days to each certification during the first quarter of 2026.

Storage costs are real. The district is currently paying for roughly 14 terabytes of redundant data across contracted cloud and on-premises systems, according to procurement records published on the Secretaría General's transparency portal in May 2026. Eliminating confirmed duplicates could reduce that footprint by an estimated 30 percent, freeing budget that city technology managers have said they want to redirect toward the Bogotá Inteligente broadband expansion program serving low-income localities including Ciudad Bolívar and San Cristóbal.

Three Decisions That Will Shape the Outcome

Three choices now sit on the desk of district officials, and each carries consequences. First: the deduplication algorithm. The city must decide whether to use automated hash-matching software, faster and cheaper, but liable to flag legitimate near-duplicate images of the same parcel taken during different surveys, or a hybrid human-machine review, which costs more but provides an auditable chain of custody. A hybrid model piloted in Chapinero between March and May 2026 processed 4,200 files and flagged a 2.3 percent error rate in the automated-only pass.

Second: archival policy. Legal advisers at the Secretaría Jurídica Distrital are weighing whether any image file tied to a property dispute currently before the Juzgados Civiles del Circuito must be frozen from deletion regardless of duplication status. A blanket litigation hold could exempt thousands of files from the cleanup, undermining the September deadline.

Third: public transparency. Advocacy groups in Candelaria and La Macarena have pushed for a public log of deleted records, accessible via Bogotá's open-data platform at datos.bogota.gov.co, so that property owners can verify their documents were not affected. The Secretaría de Planeación has not yet committed to that level of disclosure.

The September 30 date is firm, set by a directive from the Concejo de Bogotá passed in April. If the city misses it, a monthly penalty clause kicks in. District technology managers are scheduled to present a progress report to the Concejo's infrastructure commission on July 22, the first formal accountability moment since the problem became public. What officials say that morning will signal whether Bogotá's digital records are about to get cleaner or whether the backlog is set to outlast another budget cycle.
