Name: Get Point on Nearest Route

Description: Get point on "DC Advanced Lenear Referencing System Route."

Usage: The "getPointOnRoute" operation returns point(s) on the nearest corresponding route type. It accepts X and Y coordinates and a well-known ID (WKID), Route Type as "Street", "Service", "Ramp", "Alley" or "Driveway" along with the search radius in METERS (maximum search radius is 100 METERS). If Route Type is "NOT" specified, it will return point(s) on the nearest routes regardless of it's type.

Input Parameters Description:

x : X-Coordinate
y : Y-Coordinate
inSR : Input Spatial Reference in WKID
outSR : Output Spatial Reference in WKID
routeType : Targeted type of roadway, "Street", "Service", "Ramp", "Alley" or "Driveway". If blank, target all.
searchRadius: Search radius from the input point. Maximum search radius is 100 (METERS)

Return Value Description:

routeID: Main Route ID of the intersection in DCALRS Roadway network
routeName: Route name of the main RouteID
routeType: Route type of the main RouteID
roadwaySegID: Corresponding Roadway Segment ID
streetSegID: Corresponding Street Segment ID. This is returned if Route Type is 'Street'. This might be obsolete in the future.
serviceRoadSegID: Corresponding Service Road Segment ID. This is returned if Route Type is 'Service'. This might be obsolete in the future.
alleySegID: Corresponding Alley Segment ID. This is returned if Route Type is 'Alley'. This might be obsolete in the future.
streetID: Corresponding Street ID. This is returned if Route Type is 'Street' or 'Service'. This might be obsolete in the future.
directionality: Directionality of the Route at the returned point. This might be obsolete in the future.
measure: Returned point measure along the main RouteID (FEET)
measureInMeters: Returned point measure along the main RouteID (METERS)
offset: Distance between input and output points (FEET)
offsetInMeters: Distance between input and output points (METERS)
rotation: The angle that the output point should be rotated relative to the main route (DEGREES); mainly used for symbology
functionalClassCode: DC Functional Classification Code of the Route
functionalClass: DC Functional Classification of the Route
geometry: Output point geometry on the RouteID
tangentLine: Tangent line on the main RouteID at the output point geometry
tangentHorizontalAngle: The angle between tangent line and the X-axis (DEGREES)
tangentVerticalAngle: The angle between tangent line and the Y-axis (DEGREES)
