Summary of the spatial reliability levels of the 1785 historical geotechnical logs provided in Project Gatekeeper.
| Spatial reliability level | Description of spatial information | No. of test points |
|---|---|---|
| A | X and Y coordinates are provided with global position coordinate reference systems. | 128 |
| B | X and Y coordinates are provided in the log with local position coordinate reference systems. Uncertainties about the precise the coordinate reference system, were resolved using basic geospatial and engineering judgement. | 656 |
| C | X and Y coordinates are not provided and there is no coordinate reference system. Logs are referenced according to local chainages on site plans - without coordinates. | 604 |
| D | X and Y coordinates are not provided and there is no coordinate reference system. Logs are not referenced to anything. | 397 |
