ArcGIS Pro 3.4 API Reference Guide
ArcGIS.Core.Data.LinearReferencing Namespace / RouteInfo Class / LocateFeatures Method / LocateFeatures(FeatureClass,Double,EventTableConfiguration) Method
The feature class to intersect with RouteInfo.
The search radius defines how far a search will be done to find a target route.
Describes an event table to hold events information.
Example Version

LocateFeatures(FeatureClass,Double,EventTableConfiguration) Method
Computes the intersection between input features and route features and then stores the resulting route and measure information in a new event table as described by eventTableConfiguration. The search radius defines how far a search will be done to find a target route.
Syntax

Parameters

featureClass
The feature class to intersect with RouteInfo.
searchRadius
The search radius defines how far a search will be done to find a target route.
eventTableConfiguration
Describes an event table to hold events information.
Exceptions
ExceptionDescription
A geodatabase-related exception has occurred.
featureClass or eventTableConfiguration is null.
Remarks

If the featureClass is points, the searchRadius will be a numeric value defining how far around each point a search will be done to find a target route.

If the featureClass is lines, the searchRadius will be a cluster tolerance, which is a numeric value representing the maximum tolerated distance between the input lines and the target routes.

If the featureClass is polygons, the searchRadius is ignored and no search radius will be used.

Example
Locate features along routes
public void LocateLineFeaturesAlongRoutes(Geodatabase geodatabase, string routeFeatureClassName = "Roads", string eventTableName = "Accidents", string routeIdFieldName = "RID", string toMeasureFieldName = "toMeasure", string fromMeasureFieldName = "fromMeasure")
{
    // Configure events table
    EventTableConfiguration lineEventTableConfiguration = new LineEventTableConfiguration(eventTableName, routeIdFieldName, fromMeasureFieldName, toMeasureFieldName) { KeepAllFields = true, MDirectionOffset = true };

    using (FeatureClass routeFeatureClass = geodatabase.OpenDataset<FeatureClass>(routeFeatureClassName))
    using (FeatureClass highCrashAreaFeatureClass = geodatabase.OpenDataset<FeatureClass>("HighCrashRegion"))
    {
        RouteInfo routeInfo = new RouteInfo(routeFeatureClass, routeIdFieldName);

        // Creates an event table inside the geodatabase
        routeInfo.LocateFeatures(highCrashAreaFeatureClass, 0.5, lineEventTableConfiguration);

        // Open newly created event table
        using (Table eventTable = geodatabase.OpenDataset<Table>(eventTableName))
        {
            EventInfo eventInfo = new LineEventInfo(eventTable, routeIdFieldName, fromMeasureFieldName, toMeasureFieldName);

            // Create RouteEventSource using new event table
            using (RouteEventSource routeEventSource = new RouteEventSource(routeInfo, eventInfo, new LineEventSourceOptions()))
            {
                // TODO
            }
        }
    }
}
