    Could you expand & clarify please?<br>
    <br>
    What is an OSM candidate? <br>
    For Tendring, are you saying there's more entities in OSM with an
    FHRS tag than there are in the FHRS government data?<br>
    Why are the results arbitrary?<br>
    <br>

        <div>As an exercise in measuring OSM<span>’s </span>coverage I
