DataQueryFindNearbyPopulationCenter Method (LatLon, Double, UInt32, Double, CancellationToken)

public static Address FindNearbyPopulationCenter(
	LatLon location,
	double maxDistanceMeters,
	uint minPopulation,
	double sizeFactor,
	CancellationToken token
)

Public Shared Function FindNearbyPopulationCenter ( 
	location As LatLon,
	maxDistanceMeters As Double,
	minPopulation As UInteger,
	sizeFactor As Double,
	token As CancellationToken
) As Address

Parameters

location

Type: Telogis.GeoBaseLatLon
The location to query.

maxDistanceMeters

Type: SystemDouble
The maximum search radius, in meters, from the location.

minPopulation

Type: SystemUInt32
The minimum population of the location. Use 0 to include all population centers.

sizeFactor

Type: SystemDouble
A value between 0 and 1, used to determine the relative weight of distance versus population. When set to 0, the closest population center within the search area will be returned (proximity only). When set to 1, the largest population center within the search area will be returned (population only). Between 0 and 1, results will be weighted based on an interpolated score incorporating proximity and population. A value near 0.3 (mostly proximity but partly population) generally provides good results, but experimentation is recommended based on the particular use case.

token

Type: Telogis.GeoBase.ConcurrencyCancellationToken
A CancellationToken that can be used to cancel the query early, causing a DataQueryCanceledException to be thrown.

Return Value
