Locate Features Along Routes
Computes the
intersection of input features (point, line, or polygon) and route features and
writes the route and measure information to a new event table.
1. Input Features
The input point, line,
or polygon features.
2. Input Route Features
The routes with which
the input features will be intersected.
3. Route Identifier Field
The field containing
values that uniquely identify each route. This field can be numeric or
character.
4. Search Radius
If the input features
are points, the search radius is a numeric value defining how far around each
point a search will be done to find a target route.
If the input features
are lines, the search tolerance is really a cluster tolerance, which is a
numeric value representing the maximum tolerated distance between the input
lines and the target routes.
If the input features
are polygons, this parameter is ignored and no search radius is used.

calculated based on the routes' digitized direction. Input features to the left
of the digitized direction of the route will be assigned a negative (-) offset,
and features to the right of the digitized direction will be assigned a
positive offset value (+).
