- Conversion Method
- The yellow WASA Jurisdiction Area fill was isolated from the raster plate. Thin overprinted map lines were closed. The resulting contours were transformed to longitude and latitude through the printed 74 degree 10, 20 and 30 minute longitude labels and the 31 degree 20 and 30 minute latitude labels. The full method, controls, source image and QA overlay are preserved with the source geography.
- Uncertainty Notes
- Use 300 metres of horizontal uncertainty. The source is a small raster map, not survey geometry. Internal text and line work were repaired by image morphology. The layer is suitable for dated city-scale context and point inclusion well away from an edge.
- Geographic Claim
- Assignment Level
- territory
- Proves
- The official project record represented this yellow area as the Lahore WASA serving or jurisdiction area on a map compiled on 16 January 2019. Shadman Main Market falls well inside the reconstructed fill.
- Does Not Prove
- It does not prove the 2026 outer boundary, the service status of a property, a pipe connection, a sewer catchment, or the responsible WASA section, subdivision or complaint circle.
- Public Display
- context-only
- Evidence Gap
- A current WASA digital service-area layer or legal schedule, plus current internal operating-territory assignments.
