Czech Streets 18 Verified

The verification pipeline consists of four major stages, each staffed by domain experts and supported by automated tools.

| Stage | Actors | Tools & Criteria | |------|--------|-------------------| | A. Technical Validation | Data Curators (10 FTE) | • File integrity checks (SHA‑256 checksum).
• Resolution & format compliance (JPEG‑2000, GeoTIFF).
• GPS precision ≤ 3 m (post‑processed with RTK correction). | | B. Visual Quality Assurance | Image Reviewers (20 FTE) | • No obstructions (e.g., pedestrians, vehicles covering > 30 % of façade).
• Proper exposure (histogram analysis).
• Consistent lighting across overlapping shots. | | C. Contextual Authentication | Urban Historians (15 FTE) | • Cross‑reference with cadastral maps (ČÚZK) to confirm street‑segment boundaries.
• Validate building numbers and signage against municipal registers. | | D. Ethical & Legal Compliance | Legal Advisors (5 FTE) | • GDPR checks – faces & number plates blurred automatically; manual spot‑check for residual PII.
• Copyright clearance – all contributors signed a CC‑BY‑4.0 licence agreement. |

The designation "18" could refer to several things:

The most practical and likely interpretation relates to a community-driven or governmental initiative launched in late 2025 called "Czech Streets: Level 18 Verification." Under this protocol, a street cannot be marked as "fully verified" until it meets 18 distinct data points. These include: czech streets 18 verified

When a street achieves "18 verified" status, it becomes a gold-standard data asset used by navigation apps like Mapy.cz and international firms like Google Maps.

In many countries, including the Czech Republic, streets are named and numbered for easier navigation. The numbering system can vary significantly from one place to another. In the Czech Republic, streets are often numbered in a specific pattern, with main roads leading out of towns and cities being numbered sequentially. For instance, in Prague, you might find streets and roads numbered based on their direction and location relative to the city center.
