Function getCoordinateAtRouteProgress

getCoordinateAtRouteProgress(
route: Route,
query: RouteProgressQuery,
): RouteCoordinateAtProgress | undefined
Returns the geographic coordinate and cumulative progress at the route point a RouteProgressQuery identifies.

Between progress entries, positions follow the line's length, so equal steps of distance cover equal ground.
Parameters
- route: Route
  The route to query, which must contain properties.progress data.
- query: RouteProgressQuery
  Exactly one of:
  
  { traveledTimeInSeconds }, the elapsed seconds from the route start.
  
  { traveledDistanceInMeters }, the meters traveled from the route start.
  
  { clockTime }, an absolute Date. The elapsed seconds come from route.properties.summary.departureTime.
Returns RouteCoordinateAtProgress | undefined
The interpolated RouteCoordinateAtProgress, or undefined when:
- the route has no progress data
- clockTime is given but the route has no summary.departureTime
- clockTime is before the route departure time
- the progress data is incomplete for the requested position
Example
```
const byTime = getCoordinateAtRouteProgress(route, { traveledTimeInSeconds: 600 });
const byDistance = getCoordinateAtRouteProgress(route, { traveledDistanceInMeters: 5000 });
const byClock = getCoordinateAtRouteProgress(route, { clockTime: new Date('2025-06-01T09:30:00Z') });
```
