| Guide for use: | The positional uncertainty is measured in metres at the 95% confidence level, with respect to the defined reference frame. It is intended to be a measure for physical address point features. Usage Example: 10.000 | ||
| Comments: | This is a measure of the closeness of the location of the point in relation to true position on the earth. That is, we are 95% confident that the true position lies within 10 metres of the position given by the geocode. | ||
