- Conversion Method
- PDF page 59 was rendered at 180 dpi. Sparse route vertices were digitised from Figure 3-1 against its printed EPSG:32643 grid, then transformed to EPSG:4326. The three line descriptions and reported lengths were copied from section 3.2.
- Uncertainty Notes
- The features are city-scale project alignments. They are not shaft, parcel, excavation, catchment or as-built geometry. The ultimate disposal point is a map-derived site marker, not a surveyed footprint.
- Geographic Claim
- Assignment Level
- corridor
- Proves
- The 2025 approved project record maps three planned trunk alignments meeting at Qartaba Chowk and continuing to a planned ultimate disposal station at Gulshan-e-Ravi.
- Does Not Prove
- It does not prove completed construction, a current household connection, the live sewer serving a property, or that a named intermediate disposal station still operates.
- Public Display
- context-only
- Evidence Gap
- Signed construction drawings, final shaft schedule, contract progress, commissioning records and as-built GIS.
