Description
License:
The ArcGIS Location Referencing license is required to use this resource.
This operation converts one or more station values to geographic locations along a set of routes in station-enabled event layers when the isStationEvent property is true.
A status message is returned indicating either success or why the conversion failed.
Status messages
The following table contains an enumeration of the possible locating statuses:
| Status | Description |
|---|---|
esriLocatingOK | Locating was successful. |
esriLocatingMultipleLocation | Locating was successful and the input point was located on more than one route. |
esriLocatingInvalidRouteId | The route location's route ID is invalid (null, empty, or invalid value). |
esriLocatingInvalidMeasure | At least one of the route location's station values is invalid. |
esriLocatingCannotFindRoute | The route does not exist. |
esriLocatingRouteShapeEmpty | The route does not have a shape or the shape is empty. |
esriLocatingRouteMeasuresNull | The route does not have measures or the measures are null. |
esriLocatingRouteNotMAware | The route is not an m-aware polyline. |
esriLocatingNullExtent | The from station is equal to the to station. |
esriLocatingCannotFindLocation | The route location's shape cannot be found because the route has no measures or the route location's measures do not exist on the route. |
esriLocatingCannotFindExtent | The route location's shape cannot be found because the from station and the to station are outside of the route measures. |
esriLocatingFromPartialMatch | The route location's shape cannot be found because the from station is outside of the route measure range. |
esriLocatingToPartialMatch | The route location's shape cannot be found because the to station is outside of the route measure range. |
esriLocatingFromToPartialMatch | The route location's shape cannot be found because the from station and the to station are outside of the route measure range. |
Request parameters
| Parameter | Details |
|---|---|
| f | Optional parameter to specify the response format. The default response format is html. Values: html | json |
| locations | Description: A list of routes and station values to convert to geometry. Syntax: |
| temporalViewDate | The time instant to use as a temporal view date when locating route features. The parameter value is a number that represents the number of milliseconds since epoch (January 1, 1970) in UTC. Syntax: temporalViewDate=<timeInstant> Example: 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. |
| gdbVersion | The geodatabase version to use for the network feature class. This parameter applies only if the isDataVersioned property of the network layer is true. If this parameter is not specified, the published map's version is used. |
Example usage
The following are sample URLs for station to geometry.
Example 1
The following is a URL for converting a single station value to point geometry:
https://sampleserver/arcgis/rest/services/MyLRS/MapServer/exts/LRServer/eventLayers/1/stationToGeometry?f=json&locations=[{"routeId":"I90","station":"7+05.12"}]&outSR=102100Example 2
The following is a URL for converting a station range to line geometry:
https://sampleserver/arcgis/rest/services/MyLRS/MapServer/exts/LRServer/eventLayers/1/stationToGeometry?f=json&locations=[{"routeId":"I90","fromStation":"0+25.1","toStation":"0+26.8"}]&outSR=102100Example 3
The following is a URL for converting multiple stations to point geometry:
https://sampleserver/arcgis/rest/services/MyLRS/MapServer/exts/LRServer/eventLayers/1/stationToGeometry?f=json&locations=[{"routeId":"I90","station":"7+05.12"},{"routeId":"US20","station":"8+72"}]&outSR=102100Example 4
The following is a URL for converting multiple stations and station ranges to point and line geometry:
https://sampleserver/arcgis/rest/services/MyLRS/MapServer/exts/LRServer/eventLayers/1/stationToGeometry?f=json&locations=[{"routeId":"I90","fromStation":"0+25.1","toStation":"0+26.8"},{"routeId":"US20","station":"7+02.6"}]&outSR=102100Example 5
The following is a URL for converting a station range that spans different routes on the same line to line geometry:
https://sampleserver/arcgis/rest/services/MyLRS/MapServer/exts/LRServer/eventLayers/1/stationToGeometry?f=json&locations=[{"routeId":"I90", "toRouteId":"I91","fromStation":"0+25.1","toStation":"0+26.8"}]&outSR=102100JSON Response syntax
