Creates rings or drive-time areas around point features. The size of the polygons are based on a threshold variable, such as population, income, or any demographic variable.
There is no usage for this tool.
| Parameter | Explanation |
|---|---|
| inputLayer | Input points layer used for the ring or drive-time area. Input can be a be a URL to a feature service or a feature collection. |
| idField (Optional) | A field that uniquely identifies each input point and is included in the output as an attribute. |
| thresholdVariable | Business Analyst variable to which the threshold value will be applied. |
| thresholdValues (Optional) | The threshold values that determines the size of the output areas. The areas will expand until they contain the threshold value of the selected variable. |
| thresholdExpression (Optional) | A fields-based expression used for defining the threshold values. The areas will expand until they contain the threshold value. |
| distanceType | Description: Defines how distance is calculated. Valid values are a string, StraightLine, which indicates Euclidean distance to be used as distance measure, or a JSON object representing settings for a travel mode. |
| distanceUnits (Optional) | The distance units that will be used for distance calculations. Eg. Meters, Kilometers, Feet, Miles, Seconds, Minutes, Hours. Time units are only used for the network distance calculations type. |
| maxIterations (Optional) | The maximum number of times Network Analysis will iterate to find the threshold values. |
| travelDirection (Optional) | Specifies the direction of travel to calculate drive time. |
| timeOfDay (Optional) | The time and date that will be used when calculating distance. Set the time and date as Unix time in milliseconds. |
| timeZoneForTimeOfDay (Optional) | Specifies the time zone that will be used for the Time of Day parameter. |
| polygonDetail (Optional) | Specifies the level of detail that will be used for the output drive time polygons. |
| minimumStep (Optional) | The minimum increment distance or time - for example, 1 mile or 1 minute - used between iterations to expand until the threshold is reached. |
| targetPercentDifference (Optional) | The maximum difference between the target value and threshold value when determining the threshold drive time, for example, 5 percent. |
| outputName (Optional) |
There is no explanation for this parameter. |
| context (Optional) | Additional settings such as processing extent and output spatial reference. |
| useData (Optional) | Defines which data would be used to process the calculation. Sample: {"sourceCountry":"US", "hierarchy":"census"} |
