});Property Details
<String
StringThe URL to the analysis service, for example "http://analysis.arcgis.com/arcgis/rest/services/tasks/GPServer".
<String
StringThe units of the
breakValues parameter.Known values:
"Seconds" | "Minutes" | "Hours" | "Feet" | "Yards" | "Meters" | "Kilometers" | "Miles"Default value:
"Minute"<Number[]
Number[]An array of driving time break values. The numeric break value or values are passed in as an array of numbers. By setting multiple, unique values in the array, polygons of different sizes are generated around each input location.
Default value:
[ 5 , 10 , 15 ]<String
StringSets the selected folder of the select folder dropdown, based on the provided
folderId, when showSelectFolder is true. When folderId and folderName are both provided, folderId has higher precedence. (Added at v3.13)<String
StringSets the selected folder of the select folder dropdown, based on the provided
folderName, when showSelectFolder is true. (Added at v3.13)<FeatureLayer
FeatureLayerThe point feature layer around which drive-time areas will be drawn.
<Map
MapReference to the map object.
<String
StringThe name of the output layer to be shown in the Result layer name inputbox. If not specified,
"Drive from ${input_layer_title} (${time_or_distance})" will be shown by default.<String
StringThe rule of overlap. When generating areas for more than one location, the drive-time areas may converge. You can choose to let the converging areas:
Overlap- Drive-time areas from different input points may cover the same road. This is useful when you need to know all the input points that can reach a particular location within the given drive time or distance.Dissolve- All drive-time areas are merged into one, and no more than one area can cover a particular location. This is useful when all you need to know is that an area can be reached within a given time or distance, but you don't need to know which specific input points can reach the location. If multiple break values are passed in to create various drive-time areas around each input location, the areas with the same break values are dissolved together, irrespective of the input point from which they are measured.Split- The drive-time areas from different input locations that would overlap each other are split in the middle so they abut one another instead. This is useful when you want to see which areas are within a given time or distance of the input points and at the same time determine which input point is closest to that area.
Known values:
"Overlap" | "Dissolve" | "Split"Default value:
"Overlap"<Object
