FindResult.Score Property

FindResult.Score Property

The score of the found result.

Public Score As System.Double


[C#]

public System.Double Score;

Remarks

• For the FindServiceSoap.FindNearby and FindServiceSoap.FindNearRoute methods, the Score property is the distance from the search point (latLong), in distance units (DistanceUnit enumeration) as specified in the UserInfoFindHeader.DefaultDistanceUnit property.

• For the FindServiceSoap.Find and FindServiceSoap.FindAddress methods, the Score property is the confidence level of the result. The range is 0 through 1 (worst to best).

• This property has no significance for the FindServiceSoap.FindByID, FindServiceSoap.FindByProperty, and FindServiceSoap.FindPolygon methods. The Score is always 1.0 if there is a match, and 0.0 if there is no match.

• For the Find and FindAddress methods, 0.85 (the MapPointConstants.FindScoreThreshold property) is the lowest score considered good for a found result.

• To limit the returned results by score for the Find and FindAddress methods, use the FindOptions.ThresholdScore property.

Example

[Visual Basic]

'Iterate through each find result and output it
'if it is a good match
Dim findSpec As New FindSpecification()
findSpec.DataSourceName = "MapPoint.NA"
findSpec.InputPlace = "Seattle, WA"

Dim foundResults As FindResults
foundResults = findService.Find(findSpec)

Dim constants As New MapPointConstants()

Dim fr As FindResult
For Each fr In foundResults.Results
 If (fr.Score > constants.FindScoreThreshold) Then
  Console.WriteLine(fr.FoundLocation.Entity.DisplayName)
 End If
Next



[C#]

//Iterate through each find result and output it
//if it is a good match
FindSpecification findSpec  = new FindSpecification();
findSpec.DataSourceName = "MapPoint.NA";
findSpec.InputPlace = "Seattle, WA";

FindResults foundResults;
foundResults = findService.Find(findSpec);

MapPointConstants constants  = new MapPointConstants();
foreach(FindResult fr in foundResults.Results)
{
 if (fr.Score > constants.FindScoreThreshold) 
 {
  Console.WriteLine(fr.FoundLocation.Entity.DisplayName);
 }
}
