Name: Get Nearest Route Intersection

Description: Get Nearest Route Intersections on "DC Advanced Lenear Referencing System (ALRS) Route."

Usage: The "getNearestRouteIntersection" operation returns nearest route intersection point(s) on DC Roadways. It accepts X and Y coordinates and a well-known ID (WKID), Route Type as "Street", "Service", "Ramp", "Alley", "Driveway" or "Trail" along with the search radius in METERS (maximum search radius is 200 METERS). If Route Type is "NOT" used, it will return intersection(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
