Introduction
Allows you to limit the number of returned records and search distance, as well as include distance to edge, count, and index fields to the output. Setting depend on the search type selected in the Input tab.
Straight Line Distance
The following setting are applicable when you select Straight Line in the Search by section in the Input tab.
Field  Description 

Limits  These settings limit the maximum number of records that may be returned for any search geometry. To ensure the best performance for your flow and the system, it is highly recommended that at least one of these limits is set. 
Limit the number of returned records 
By default this option is selected with a default value of 1. If it is not selected, all nearest points of interest that are within the specified distance are returned. This might affect performance. A value specified in the MaxCandidates input field will override this setting. 
Limit the search distance 
By default this option is selected with a value of 1 mile. Valid values are > or = 0, however a search distance of 0 will return only results that intersect the input geometry. Values specified in the MaxDistance and MaxDistanceUnit input fields will override this setting. 
Distance unit 
Available units are:

Distance  The distance field contains the shortest distance from an input geometry to the geometry of the returned record. The distance to edge field contains the distance between the two closest edges of the input geometry and the geometry of the returned record (for an input point, this is the distance between the point and the edge of a polygon). 
Include distance 
This option (which is selected by default) is useful when you want to know the shortest distance from an input geometry to the returned record. 
Distance field  Specifies the shortest distance from an input geometry to the returned record. When the returned record contains or intersects the input, the distance returned will be zero. 
Distance unit field  Specifies the name of the output field that will hold the distance unit. 
Distance unit  Specifies the unit of measure of the returned distance. Available
units are:

Include distance to edge 
This option is useful when you need to know how close a point is to the edge of a geometry. It is not selected by default. 
Distance to edge field  Specifies the name of the output field that will hold the distance
to edge. Always contains the shortest distance to the edge; that is, the
distance between the two closest points of the input geometry and the
geometry of the returned record. The unit of the returned distance will
be same as that selected in the Distance unit
dropdown list above. Geometries with intersecting edges will return zero. If one geometry fully contains the other, the field will return a distance value. 
Count  The count field contains the total number of records returned for each input. The index field contains the current record's order in the total count. 
Include count and index 
This option is useful when you have many records being returned and need to identify different records from each other. 
Count field  Specifies the name of the output field that contains the total number of records returned for each input. 
Index field 
Specifies the current recordâ€™s order in the collection of output records. For example, "1 of 5" has a count of 5 and an index of 1. 
Closest point  The closest point of the input geometry and to the input geometry. 
Return nearest point of input geometry  Specifies the nearest point for the input geometry. It returns the closest input point. In case of the point (when you select longitude and latitude in the input), the nearest point is the point itself that you provided as an input. In case if you picked up a polygon (when you select a geometry in the input), the nearest point is the edge of the polygon in which the input point lies. 
Return nearest point to input geometry  Specifies the nearest Point of Interest (Point of Interest). In case if you have provided point as an input, the nearest POI will be a point. In case if the input is a polygon, the nearest POI will be on the edge of the polygon. 
Route Network Distance
The following setting are applicable when you select Route Network Distance in the Search by section in the Input tab.
Field  Description 

Database  The name of the database that contains the routing data to use to determine the shortest or fastest route. Use the database name specified in the Management Console's Database Resources tool. For more information, see Creating a Routing Database Resource. 
Route Limits  These settings allow you to select whether you wish to find the nearest points of interests for a specific distance or a time frame from the input point. 
Limit travel distance  Specifies the distance for which you wish to find the nearest points of interest. 
Distance unit  Specifies the unit of measure of the returned distance. Available
units are:

Limit travel time 
Specifies the time length for which you wish to find the nearest points of interest. For example, you may want to calculate the point of interest that fall in a time length of five minutes. 
Time unit  Specifies the unit of measure of the returned time. Available
units are:

Limit number of returned records  Specifies the number of points of interests you wish to calculate in the output. 
Routing Output  These settings allow you define the way output of the nearest point of interest is displayed. 
Distance field  Specifies the shortest distance from an input geometry to the returned record. When the returned record contains or intersects the input, the distance returned will be zero. This option is useful when you want to know the shortest distance from an input geometry to the returned record. 
Distance unit field  Specifies the name of the output field that will hold the distance unit. 
Distance unit  Specifies the unit of measure of the returned distance. Available
units are:

Time field  Specifies the name of the output field that holds the time value calculated from given start to end. It is available in the output only if the check box against it is selected. This option is useful when you want to know the shortest distance from an input geometry to the returned record in a stipulated time frame. 
Time unit field  Specifies the name of the output field that holds the time unit against the calculated time from given start to end. It is available in the output only if the check box against the Time field is selected. 
Time unit  Specifies the value that is set against the Time unit field. It has the following
values:

Count field  This option allows you to setup a field to display the count of the total records returned by the stage. 
Index field  This option signifies the sequence index of each of the records based on the time elapsed in fetching the records. 
Routing Settings  These settings allow you to include various routing capabilities for the calculations. 
Historic time bucket 
Specifies whether the routing calculation uses the historic traffic speeds. These speeds are based on different timeofday buckets. The data must have historic traffic speeds included to use this feature. The data for each country and region has the same bucket definitions, where the speeds for these bucket values may vary. The options are:

Only use major roads  Specifies whether to include all roads in the calculation or just major roads. If you choose to include only major roads, performance will improve, but accuracy may decrease. This field is available on input from the previous stage. It represents a Boolean value where the default value is True. 
Max off road distance  Specifies the maximum distance to allow travel off the road network. Examples of offnetwork roads include driveways and access roads. For example, if you specify a maximum offroad distance of 1 mile (default value and unit), the travel boundary will extend no further than one mile from the network road. Use the ambient speed options to specify the speed of travel along nonnetwork roads. The default value is 0.5. 
Distance unit  Specifies the unit of measure of the returned distance. Available
units are:

Default ambient speed  Specifies the ambient speed to use for offnetwork travel based on the road type. If you do not specify an ambient speed for a road type, the default ambient speed will be used, as specified in the DefaultAmbientSpeed text box. This option is applicable only when you specify a time value in the TravelCostUnits option. This field is available on input as DefaultAmbientSpeed from the previous stage. The default value is 15 
Speed unit  Available units are:

Simplification factor  Specifies the percentage of the cost used to calculate the distance between the starting point and the isodistance. The propagation factor serves the same purpose for isodistances as ambient speed does for isochrones, that is, it controls how offnetwork travel is used in the travel boundary calculation. Propagation factor can affect the size and shape of the travel boundary polygon. In general, more the propagation factor value, the larger the polygon. This is similar to ambient speed, except that it applies to isodistances. The default value for this property is 0.16. If this property is not specified, then the calculation uses the server setting. This field is available on input as PropagationFactor from the previous stage in which the user can override the Settings value from the input. Valid values are between 0.0 and 1.0, both inclusive. 
Propagation factor  Specifies what percentage of the original points should be returned or upon which the resulting polygon should be based. This field is available on input asSimplificationFactor from the previous stage. It carries values between 0 and 1 and the default value is 0.5.
