Query Attribute Set

URL:: https://<network-layer-url>/queryAttributeSet
Methods:: GET
Required Capability:: The ArcGIS Location Referencing license is required to use this resource.
Version Introduced:: 10.6

Description

This operation segments event layers for selected routes where any measures change across the attribute set based on different measures or measure ranges. The result of this operation is a feature set that contains the values for the fields included in an attribute set and some additional fields that contain the route ID and measures from the network on which the query is performed. The geometry of each feature is also returned in the feature set.

Request parameters

Parameter Details

Parameter	Details
`f` (Optional)	Specifies the response format. The default response format is `html`. Values: `html` \| `json` \| `pjson`
`locations` (Required)	A list of routes and measure values used to segment event layers. The list can be either all single measures or all measure ranges; it can't mix single measures and measure ranges. Each route can have one or more different measures. If only a `routeId` is provided, the entire route is returned. Syntax: Use dark colors for code blocksCopy `1 2 3 4 5 6 7 8 9 10 11 [ { // syntax of a single measure "routeId": "<routeId1>", "measure": <measure1> }, { "routeId": "<routeId1>", "measure": <measure2> } ... ]` or Use dark colors for code blocksCopy `1 2 3 4 5 6 7 8 9 10 11 12 13 [ { // syntax of a measure range "routeId": "<routeId1>", "fromMeasure": <measure1>, "toMeasure": <measure2> }, { "routeId": "<routeId1>", "fromMeasure": <measure3>, "toMeasure": <measure4> } ... ]` or Use dark colors for code blocksCopy `1 2 3 4 5 6 7 8 9 [ { // syntax to return the entire route "routeId": "<routeId1>" }, { "routeId": "<routeId2>" } ... ]`
`attributeSet`	An attribute set that contains the linear event layers to query and fields to include in the result. The linear event layer can also be a Utility Network pipeline layer that has been configured as an LRS centerline using the Configure Utility Network Feature Class geoprocessing tool, or an address block range layer that has been configured as an LRS centerline using the Configure Address Feature Classes geoprocessing tool. When the centerline layer is an Address feature, the centerline direction is honored in the output. The object ID field for each layer specified will always be included in the results. If a field name already exists across all layers, it is renamed. Syntax: Use dark colors for code blocksCopy `1 2 3 4 5 6 7 8 9 10 11 [ { "layerId" : "<layerId1>", "fields" : [ "<field1>", "<field2>", "<field3>", ... ] }, { "layerId" : "<layerId2>", "fields" : [ "<field1>", "<field2>", ... ] }, ... ]`
`temporalViewDate`	The time instant to use as a temporal view date when locating route features. If this parameter is not specified, the current date is used. The parameter value is a number that represents the number of milliseconds since epoch (January 1, 1970) in UTC. Syntax: Use dark colors for code blocksCopy `1 temporalViewDate=<timeInstant>` Example: Use dark colors for code blocksCopy `1 temporalViewDate=1230768000000 (1 Jan 2009 00:00:00 GMT)`
`outSR`	The spatial reference of the returned geometry. The spatial reference can be specified as either a Well-Known ID (WKID) or a spatial reference JSON object. If `outSR` is not specified, the geometry is returned in the spatial reference of the map service.
`gdbVersion` (Optional)	Specifies the geodatabase version to use. If this parameter is not specified, the published map's version is used. Syntax: Use dark colors for code blocksCopy `1 gdbVersion=<version>` Example: Use dark colors for code blocksCopy `1 gdbVersion="user1.version1"`
`historicMoment` (Optional)	Specifies the historic moment to query. This parameter applies only if the layer is branch versioned and refers to geodatabase time (separate from LRS time). If this parameter is not specified, the query applies to the current features. Syntax: Use dark colors for code blocksCopy `1 historicMoment=<epoch time in milliseconds>` Example: Use dark colors for code blocksCopy `1 historicMoment=1514764800000`

locations

(Required)

attributeSet

An attribute set that contains the linear event layers to query and fields to include in the result. The linear event layer can also be a Utility Network pipeline layer that has been configured as an LRS centerline using the Configure Utility Network Feature Class geoprocessing tool, or an address block range layer that has been configured as an LRS centerline using the Configure Address Feature Classes geoprocessing tool.
