We've all gotten lost at some point in our lives. Finding out where we are, where we want to go, and how to get there is hard enough for people, but it’s even harder for our applications and devices. Fortunately, map and location APIs are here to help. From latitudes to longitudes, from geocoding to routing, in this session you'll learn to go beyond maps and help your apps and devices find their way using location technology.

1. Where am I?

5. We’re never really lost anymore.

6. Location Technology
Location technology is an integral part of our daily lives.

12. Where am I?

13. Example: Browser Geolocation API
navigator.geolocation.getCurrentPosition(function(position) {
document.write(position.coords.latitude + ", " +
position.coords.longitude);
});

14. Example: HERE Android Positioning API
PositioningManager positioningManager =
PositioningManager.getInstance();
positioningManager.start(
PositioningManager.LocationMethod.GPS_NETWORK);
GeoPosition position = positioningManager.GetPosition();

15. So we are at 37.3723, -121.9222. What does that mean?
Latitude & Longitude
Latitude Longitude
Equator
Prime Meridian
+60
-30
-90 (South)
+90 (North) 180
-120 (West)
+30 (East)

16. How did we get the location?

17. How did we get the location?
GPS

18. How did we get the location?
GPS, GALILEO, GLONASS, BeiDou, NAVIC, QZSS
GNSS

19. How did we get the location?
GNSS isn‘t the only way to get a location.
Radio signals:
Cell towers, Wifi, Bluetooth, etc

20. Example: HERE Positioning API
https://pos.api.here.com/positioning/v1/locate?
app_id=YOUR_APP_ID
&app_code=YOUR_APP_CODE
credentials
{
"wlan": [
{"mac": "8C-1A-BF-20-66-AD"},
{"mac": "A0-E4-53-E9-66-A7"},
...
{"mac": "B8-6B-23-09-87-B1"},
{"mac": "F4-55-95-11-2C-C1"}
]
}

21. Where am I?
Use a Positioning API.
Understand the technology the location comes from.
Choose the right API for the right task/device.

22. Where am I?
By themselves a latitude and longitude aren‘t always helpful.
Their power is in placing us on a map.

23. Maps
Making Maps is hard.

27. Map APIs
Map Image API Interactive Map API

28. Example: HERE Map Image API
https://image.maps.api.here.com/mia/1.6/mapview?
&c=37.37774, -121.92186
&z=16
&w=640
&h=400

zoom level
Image width and height

29. Example: HERE Map Image API
https://image.maps.api.here.com/mia/1.6/route?
&r0=52.540867,13.262444,
52.536691,13.264561,

30. Example: HERE Interactive Maps API
var platform = new H.service.Platform({
app_id: ’1234567890',
app_code: abcdefghi',
useHTTPS: true
});
var defaultLayers = platform.createDefaultLayers();
var map = new H.Map(document.getElementById('map'),
defaultLayers.normal.map);
var behavior = new H.mapevents.Behavior(new
H.mapevents.MapEvents(map));
var ui = H.ui.UI.createDefault(map, defaultLayers);

31. Where am I?
2161 N. First St
San Jose, California 95131

32. Where am I?
2161 N. First St

Invalidenstraße 116

33. Geocoder API
37.37627, -121.922569

34. https://reverse.geocoder.api.here.com/6.2/reversegeocode.json?
&mode=retrieveAddresses
&prox=52.5319841,13.3828921
Example: HERE Geocoder API
https://geocoder.api.here.com/6.2/geocode.json?
&searchtext=2161+n+first+st+san+jose+california+95131
return the closest street address
location (and radius)

35. What‘s around us?
Maps provide context for a location.
Places (points of interest) are another type of context.

36. Where do I want to go?
Location isn‘t just about where you are. It‘s about where you‘re going.

37. Example: HERE Places API
// creates a Search entrypoint
var search = new H.places.Search(platform.getPlacesService());
// creates parameters for search request
var params = {
'q': 'starbucks',
'at': '37.3720,-121.9221'
};
// creates a request with callbacks
search.request(params, {}, onResult, onError);
function onResult(result) {}
function onError(error) {}

38. Example: HERE Interactive Maps API
var group = new H.map.Group();
group.addObjects(places.map(function (place) {
var marker = new H.map.Marker({lat: place.position[0],
lng: place.position[1]})
return marker;
}));
map.addObject(group);
map.setViewBounds(group.getBounds());

39. How do I get there?
Find your way using the Routing API.

40. Example: HERE Routing API
https://route.api.here.com/routing/7.2/calculateroute.json?
waypoint0=37.377,-121.921
&waypoint1=37.615,122.393
&mode=fastest;car;traffic:enabled
start and end point
routing mode

41. What can I reach?
Isoline Routing API
Which places can a delivery truck or taxi reach within 15 minutes?

42. Example: HERE Isoline Routing API
#07
var routingParams = {
'mode': 'fastest;car;',
'start': '37.80531,-122.4161',
'range': '900',
'rangetype': 'time'
};
var router = platform.getRoutingService();
router.calculateIsoline(
routingParams,
onResult,onError;
});

43. Location is solved!
(sort of)

44. But: The Future is coming!

45. The Future™
10 Billion People
Giant Cities
Autonomous cars
Autonomous everything!
Everything is a sensor! New mobility concepts
