Getting Started

``typescript
import { VPSLocationSource } from '@wemap/positioning';

const locationSource = new VPSLocationSource({
vps: {
endpoint: 'https://vps.example.com'
}
});

locationSource.onUpdate((pose) => {
console.log('Position:', pose.position);
console.log('Attitude:', pose.attitude);
});

await locationSource.start();
`

Map Matching

Use map matching to project positions onto a route:

`typescript
import { MapMatching } from '@wemap/positioning';
import { Router } from '@wemap/routing';

const router = new Router();
const itineraries = await router.directions(origin, destination, 'WALK');
MapMatching.setItinerary(itineraries[0]);
