OPERATIONAL CASE · INFRASTRUCTURE · 45A04
The 45A04 Bogotá–Cajicá corridor and its inventoried bridges
The viewer connects a national road line to published point assets around it. Users can follow the corridor, open each bridge and inspect the record date without turning inventory age into a structural diagnosis.
This workflow demonstrates one GeoSAT OpenGIS capability. It does not prove universal equivalence with MapGIS or a specific installation: validation is performed workflow by workflow.

What the loaded extent answers
The sample contains a normalized 37.18 km alignment and nine bridges associated with route 45A04 inside the Bogotá–Cajicá extent. All nine records have an inspection date in the source; some dates are historical. Published presence, date and material can organize verification, but do not establish current condition, safety, closure or intervention priority.
GeoSAT OpenGIS
A navigable inventory without an invented condition score
The demo shows how to combine network and assets while preserving exactly what the source does and does not publish.
- 01
Select the corridor
The query is allowlisted by segment code and sector; it does not download the full national road network.
- 02
Associate assets
Bridges are queried by route and spatial extent, then normalized as points with name, date and public attributes.
- 03
Separate date from condition
The interface shows when an asset was recorded or inspected and states that the date is not a safety finding.
- 04
Inspect and share
Users select the corridor or a bridge, measure, generate a shareable URL and export only loaded or selected geometry.
Demonstrated in this viewer
- A linear network combined with related point assets.
- Linked selection across map, indicators and an accessible list.
- Normalized attributes without phone numbers, responsible-person fields or internal identifiers.
- Bounded export with source, license, cutoff and attribution.
What this map cannot establish
- It does not determine structural condition, passability, closure or bridge safety.
- An old date does not automatically mean an overdue inspection or intervention priority.
- The corridor is limited to the queried sector and extent; it is not the full national route.
- Engineering decisions require technical records, inspection and the competent authority.

Open source ↗Questions about this case
Does an old inspection date mean a bridge is in poor condition?
No. The date documents a source record. Without an official rule, technical file and current inspection, condition and priority are not inferred.
Does the viewer include every bridge on route 45A04?
It includes nine records returned by the allowlisted query inside the Bogotá–Cajicá extent. It is not presented as an exhaustive inventory of the full route.
