There are seven PQI values for the positional quality of CPLCs. The order shown indicates the level of quality associated with the PQI; PQ10 is the most accurate and PQ90 the least. The PQI assigned to the CPLC will depend on the coordinates available in ADDRESS-POINT to generate the CPLC. If the ADDRESS-POINT PQI is PQ3, the best it can be, then the Code-Point Open PQI will be PQ10."^^ ; rdfs:isDefinedBy ; rdfs:label "Positional Quality Indicator"^^ ; rdfs:subClassOf . a foaf:Document ; rdfs:seeAlso ; dct:license ; dct:title "Description of http://data.ordnancesurvey.co.uk/ontology/postcode/PositionalQualityIndicator" ; foaf:primaryTopic .
