Elevation API¶
Free
Starter
Standard
Professional
The Stadia Maps elevation API allows you to get the elevation of any point on earth. You can query at a single point or build a profile along a shape.
Endpoint: https://api.stadiamaps.com/elevation/v1
Getting an elevation profile for a route?
Our routing API can return an elevation profile along the route
if you set the elevation_interval
parameter.
This has special handling for bridges and tunnels,
which is not possible in the Elevation API.
Data from the routing API is sampled at 30m from the original sources,
so if you need a higher sampling resolution,
use the Elevation API instead.
Refer to the elevation section of our routing guide to learn how to get elevation with a route.
Example Code¶
Installation Instructions
The Stadia Maps JavaScript/TypeScript SDK is available for any package manager that supports the npm registry.
npm install @stadiamaps/api
yarn add @stadiamaps/api
bun add @stadiamaps/api
import { GeospatialApi, Configuration } from '@stadiamaps/api';
// If you are writing for a backend application or can't use domain-based auth,
// then you'll need to add your API key like so:
//
// const config = new Configuration({ apiKey: "YOUR-API-KEY" }); (1)
// You can also use our EU endpoint to keep traffic within the EU using the basePath option:
// const config = new Configuration({ basePath: "https://api-eu.stadiamaps.com" });
// const api = new GeospatialApi(config);
const api = new GeospatialApi();
// Example of a point request. You can also pass multiple geographic coordinates in a list or a Google
// encoded Polyline via the encodedPolyline parameter.
const req = {id: "Seoul", shape: [{lat: 37.56, lon: 126.99}]};
const res = await api.elevation({ heightRequest: req });

Installation Instructions
The Stadia Maps Python SDK is available through any package manager that supports PyPi.
pip install stadiamaps
poetry add stadiamaps
import os
import stadiamaps
from stadiamaps.rest import ApiException
# You can also use our EU endpoint to keep traffic within the EU like so:
# configuration = stadiamaps.Configuration(host="https://api-eu.stadiamaps.com")
configuration = stadiamaps.Configuration()
# Configure API key authentication (ex: via environment variable). (1)
configuration.api_key['ApiKeyAuth'] = os.environ["API_KEY"]
with stadiamaps.ApiClient(configuration) as api_client:
# Create an instance of the API class
api_instance = stadiamaps.GeospatialApi(api_client)
try:
# Example of a point request. You can also pass multiple geographic coordinates in a list or a Google
# encoded Polyline via the encoded_polyline parameter.
req = stadiamaps.HeightRequest(id="Seoul", shape=[stadiamaps.Coordinate(lat=37.56, lon=126.99)])
res = api_instance.elevation(req)
except ApiException as e:
# Add your error handling here
print("Exception when calling the Stadia Maps API: %s\n" % e)

Installation Instructions
If aren't already using Maven Central, add the repository in your Gradle build script.
repositories {
mavenCentral()
}
Then, add the API package and its dependencies.
dependencies {
val retrofitVersion = "2.11.0"
// API package
implementation("com.stadiamaps:api:3.2.1")
// Dependencies

Installation Instructions
Our Swift SDK is distributed using the Swift Package Manager (SPM).
Apple's documentation
shows how to add a Swift Package dependency to your Xcode project.
On the Add Package screen, you can find our package by its repository URL: https://github.com/stadiamaps/stadiamaps-api-swift
.
import StadiaMaps
// This setup code can go anywhere before you actually make an API call (typically in your app init)
func setupStadiaMapsAPI() {
// Set your API key (1)
StadiaMapsAPI.customHeaders = ["Authorization": "Stadia-Auth YOUR-API-KEY"]
// Optionally use our EU endpoint to keep traffic within the EU
// StadiaMapsAPI.basePath = "https://api-eu.stadiamaps.com"
}
// This function demonstrates how to call the Stadia Maps API.
// If you have not yet adopted async/await in your Swift codebase, you can use the Task API
// to call async functions in a non-async context: https://developer.apple.com/documentation/swift/task.
func myFunction() async throws {
let req = HeightRequest(id: "Seoul", shape: [Coordinate(lat: 37.56, lon: 126.99)])
let res = try await GeospatialAPI.elevation(heightRequest: req)
// Do something with the response...
print(res)
}
