# UNCERTAINTY_IN_PRECISION - AtlasOfLivingAustralia/ala-dataquality Wiki

# Description

The uncertainty in metres value appears to be transposed with the precision value.

# Implications and caveats

**Severity: Warning**

The ALA compares the decimal latitude and longitude values provided (and the number of decimal places) with the values given for coordinate precision and the uncertainty in metres. Where the number of decimal places supplied in the coordinates doesn't match the precision given (or the number of decimal places the coordinates may be provided in) but does match the uncertainty in metres (the radius of a circle within this location could be enclosed), this assertion is raised.

Indicates the number of decismal places being supplied for coordinates for the record don't match the coordinate precision value, and are likely transposed.

# Data custodian recommendations

Review Coordinate Precision, Coordinate Uncertainty in Metres and decimal coordinates supplied for the record.
