to recommend essentially the most environment friendly route for pickups and deliveries. As the driving force follows the route, SnaptoRoads
supplies exact visualization of their location, enhancing the shopper’s real-time monitoring expertise.
Enhanced Location Service in motion
Calling the API is simple. You should use the AWS Command Line Interface (AWS CLI), considered one of our AWS SDKs, or the plain REST API. Nonetheless, displaying the knowledge on a map in an internet or cell app requires some extra setup. Though the method is effectively documented, it’s too detailed to cowl totally right here. On this demo, I’ll concentrate on utilizing the API.
Amazon Location Service permits API calls to be authenticated in two methods: by means of AWS API authentication (AWS Sigv4 authentication) or by means of API keys. API keys will be extra handy for builders of cell purposes the place the top consumer is just not authenticated or when integrating with Amazon Cognito is just not possible. That is the really useful authentication technique for front-end purposes.
To display the flexibility of the APIs and the way simply you possibly can combine inside your purposes, I exploit a mixture of the AWS CLI, cURL, and a graphical REST API consumer for every step of the demo.
Step 1: Create an API key
First, I create an API key for my utility utilizing the AWS CLI. You can even handle API keys within the AWS Administration Console.
REGION=eu-central-1
KEYNAME=geo-key-seb
aws location create-key --region ${REGION} --key-name ${KEYNAME} --restrictions
AllowActions="geo-routes:*","geo-places:*","geo-maps:*",
AllowResources="arn:aws:geo-routes:${REGION}::supplier/default",
"arn:aws:geo-places:${REGION}::supplier/default",
"arn:aws:geo-maps:${REGION}::supplier/default"
--no-expiry
{
"Key": "v1.public.ey...cy",
"KeyArn": "arn:aws:geo:eu-central-1:02345678901:api-key/geo-key-seb",
"KeyName": "geo-key-seb",
"CreateTime": "2024-09-29T09:35:53.115000+00:00"
}
This command generates the API key, which I can now use to name Amazon Location APIs.
Step 2: Get geographic coordinates
Subsequent, I exploit cURL
to retrieve the geographic coordinates (a longitude and latitude) for town heart of Lille, France, by calling GeoCode
and passing an tackle within the QueryText
parameter.
$ curl --silent -X "POST" "https://locations.geo.eu-central-1.amazonaws.com/v2/geocode?key=v1.public.ey...cy"
-d $'{ "QueryText": "Grand Place, Lille, France" }'
{"ResultItems":[{"PlaceId":"AQ...5U","PlaceType":"Street","Title":"Grand'Place, 59800 Lille, France",
"Address":{"Label":"Grand'Place, 59800 Lille, France",
"Country":{"Code2":"FR","Code3":"FRA","Name":"France"},
"Region":{"Code":"HDF","Name":"Hauts-de-France"},"SubRegion":{"Name":"Nord"},
"Locality":"Lille","District":"Centre","PostalCode":"59800",
"Street":"Grand'Place","StreetComponents":[{"BaseName":"Grand'Place","Language":"fr"}]},
"Place":[3.06361,50.63706],
"MapView":[3.0628,50.6367,3.06413,50.63729],
"MatchScores":{"General":1,"Elements":{"Deal with":{"Nation":1,"Locality":1,"Intersection":[1]}}}}]}
This returns a number of information factors, together with the GPS coordinates for town heart: [3.06361, 50.63706].
Step 3: Seek for close by locations
Utilizing the coordinates retrieved, I exploit a REST API consumer instrument to name the SearchNearby
API to seek out locations of curiosity round Lille’s metropolis heart.
On the correct aspect of the display screen, I can learn the API response: a listing of close by locations, resembling eating places, banks, and parking areas. I can additional refine the search by specifying classes or limiting the search space.
The SearchNearby
API accepts an non-compulsory Filter
parameter that helps you prohibit the search inside a bounding field or to incorporate or exclude enterprise chains, classes, nations, or meals varieties.
"Filter": {
"BoundingBox": [ number ],
"ExcludeBusinessChains": [ "string" ],
"ExcludeCategories": [ "string" ],
"ExcludeFoodTypes": [ "string" ],
"IncludeBusinessChains": [ "string" ],
"IncludeCategories": [ "string" ],
"IncludeCountries": [ "string" ],
"IncludeFoodTypes": [ "string" ]
},
In my seek for close by factors of curiosity, one of many outcomes returned was a McDonald’s, a well known worldwide reference 🍔.
Step 4: Get driving instructions
Lastly, I exploit the AWS CLI to calculate driving instructions between two metropolis facilities: Brussels, Belgium, and Lille, France.
aws location calculate-routes
--origin 4.35278 50.84687
--destination 3.06361 50.63706
--key "v1.public.ey...cy"
The response features a polyline for rendering the trail on a map and a step-by-step record of driving instructions.
...
"TravelMode": "Automotive",
"Sort": "Car",
"VehicleLegDetails": {
"TravelSteps": [
{
"Duration": 15,
"Distance": 75,
"ExitNumber": [],
"GeometryOffset": 0,
"Sort": "Depart"
},
{
"Length": 10,
"Distance": 8,
"ExitNumber": [],
"GeometryOffset": 2,
"Sort": "Flip",
"TurnStepDetails": {
"Intersection": [],
"SteeringDirection": "Proper",
"TurnIntensity": "Typical"
}
},
...
Step 5: Displaying the driving instructions on a map
To visualise the route on a map, I exploit the MapLibre library, which is a rendering engine for displaying maps in net and cell purposes. Following the Amazon Location Service Developer Information, I constructed a primary app to show the route.
Along with MapLibre, you should use AWS Amplify to combine and show Amazon Location information in your purposes.
