introduction to map and location apis (silicon valley code camp 2017)

Where amI?

We’re never really lostanymore.

LocationTechnology

Locationtechnology is anintegralpart of our daily lives.

LocationTechnology"80%of alldata is connected to location."

Where amI?

Example:BrowserGeolocation API

navigator.geolocation.getCurrentPosition(function(position) {document.write(position.coords.latitude + ", " +

position.coords.longitude);});

Example:HEREAndroidPositioning API

PositioningManager positioningManager =PositioningManager.getInstance();

positioningManager.start(PositioningManager.LocationMethod.GPS_NETWORK);

GeoPosition position = positioningManager.GetPosition();

Sowe are at37.3723,-121.9222.Whatdoesthatmean?

How did weget thelocation?


GPS


GPS,GALILEO,GLONASS,BeiDou,NAVIC,QZSS

GNSS


GNSSisn‘t theonly way toget alocation.

Radiosignals:Celltowers,Wifi,Bluetooth,etc

Example:HEREPositioning 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"}

] }

Where amI?

Use aPositioning API.

Understand the technology the location comes from.Choose therightAPIfortherighttask/device.

WhereamI?By themselves alatitude and longitude aren‘t always helpful.

Their poweris inplacing us onamap.

Map APIs

Map ImageAPI InteractiveMap API

Example:HEREInteractiveMaps APIvar 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(newH.mapevents.MapEvents(map));

var ui = H.ui.UI.createDefault(map, defaultLayers);

What‘s around us?Maps provide context for alocation.

Places(points of interest)are another typeof context.

WheredoIwant togo?

Locationisn‘t justabout where youare.It‘s about where you‘re going.

Example:HEREPlacesAPI

// creates a Search entrypointvar search = new H.places.Search(platform.getPlacesService());// creates parameters for search requestvar params = {

'q': 'starbucks','at': '37.3720,-121.9221'

};// creates a request with callbackssearch.request(params, {}, onResult, onError);

function onResult(result) {}

function onError(error) {}

Example:HEREInteractiveMaps 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());

How doIget there?Findyour way using the RoutingAPI.

Example:HERERoutingAPI

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

What can Ireach?Isoline RoutingAPI

Which places can adelivery truck or taxi reach within 15minutes?

Example:HEREIsoline RoutingAPI

#07

var routingParams = { 'mode': 'fastest;car;', 'start': '37.80531,-122.4161', 'range': '900', 'rangetype': 'time'

};

var router = platform.getRoutingService();

router.calculateIsoline(routingParams,onResult,onError;});

Locationis solved!(sort of)
