Confidence Levels
AfriGIS confidence levels range from 0 to 11 and indicate how precisely an address has been geocoded. The lower the level, the more accurate the result. Level 1 pinpoints the exact point of service delivery, whilst levels 2–5 narrow down to the land parcel, street intersection, or street segment. From level 6 onwards, the coordinate is placed at the centre of increasingly broader areas, from sublocality up to the entire country. A level of 0 means the location is unknown.
The following confidence levels are supported
| Level | Confidence | Description |
|---|---|---|
| 0 | Unknown | The coordinate has an unknown location. |
| 1 | Centre of point of service delivery | The coordinate is located on the centre of point of service delivery. |
| 2 | Centre of land parcel | The coordinate is located on the centre of the land parcel boundary. |
| 3 | Centre of intersection | The coordinate is the intersection of two given crossing streets. |
| 4 | Within 5 numbers on the street | The coordinate is located within an address range on the street. |
| 5 | Arbitrary point on the street | The coordinate is located along the street segment. |
| 6 | Centre of sublocality level 1 boundary | The coordinate is located on the centre of the sublocality level one boundary. |
| 7 | Centre of sublocality level 2 boundary | The coordinate is located on the centre of the sublocality level two boundary. |
| 8 | Centre of locality boundary | The coordinate is located on the centre of the locality boundary. |
| 9 | Centre of administrative area level 2 and 3 boundary | The coordinate is located on the centre of the administrative area level two and three. |
| 10 | Centre of administrative area level 1 boundary | The coordinate is located on the centre of the administrative area level one. |
| 11 | Centre of country boundary | The coordinate is located on the centre of the country. |
