The Actor is free to use, and you only pay for the Apify platform usage, which gets cheaper the higher subscription plan you have.

Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases. In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours, and optionally produces a well-defined JSON output, datasets with results, or files in key-value store. In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server. Actors are written with capital "A". ## How to integrate an Actor? If asked about integration, you help developers integrate Actors into their projects. You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready. The best way to integrate Actors is as follows. In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js.md): ```bash npm install apify-client ``` In Python projects, use official [Python client library](https://docs.apify.com/api/client/python.md): ```bash pip install apify-client ``` In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md): ````bash # MacOS / Linux curl -fsSL https://apify.com/install-cli.sh | bash # Windows irm https://apify.com/install-cli.ps1 | iex ```bash In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/platform/integrations/mcp.md). If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md). For usage examples, see the [API](#api) section below. For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt). # README ## French Elevation Lookup (IGN Altimetry) **Batch elevation / altitude lookup** for GPS coordinates using the **official IGN Geoplateforme altimetry API** (Institut national de l'information geographique et forestiere). Over France it uses **RGE ALTI**, one of the most precise public elevation models available (down to 1 m grid); elsewhere it falls back to a worldwide dataset. Obtenez l'**altitude precise** de coordonnees GPS via l'API officielle IGN. This actor is **free** — you only pay your own Apify platform usage. ### Input | Field | Type | Description | |---|---|---| | `coordinates` | array of strings | Points as `"latitude,longitude"` (WGS84 decimal), e.g. `"48.8566,2.3522"`. | ### Output One item per point, `status` = `found` / `not_found` / `error`: ```json { "status": "found", "input": "48.8566,2.3522", "latitude": 48.8566, "longitude": 2.3522, "elevationM": 34.83, "accuracy": "Variable suivant la source de mesure", "source": "IGN Geoplateforme (RGE ALTI / world)" } ```` ### Use cases - Enrich real-estate, agriculture or insurance datasets with precise ground elevation. - Outdoor & sports apps: altitude of trailheads, summits, race checkpoints. - Flood-risk screening: compare property elevation with nearby river levels. - Solar/telecom site planning: quick terrain elevation checks in batch. ### Limitations & fair use Free public IGN service (Geoplateforme, open licence): requests are batched (20 points/call) with polite delays. Highest precision over France and French overseas territories; worldwide fallback is coarser. `-99999` sentinel values are returned as `not_found`. ### More actors by this developer More French open-data actors (BAN geocoder, communes lookup, Georisques...) on [the developer profile](https://apify.com/vigilant_jasmine). # Actor input Schema ## `coordinates` (type: `array`): GPS points as "latitude,longitude" (WGS84 decimal degrees), e.g. "48.8566,2.3522". One dataset item per point. ## Actor input object example ```json { "coordinates": [ "48.8566,2.3522", "45.8326,6.8652" ] } ``` # API You can run this Actor programmatically using our API. Below are code examples in JavaScript, Python, and CLI, as well as the OpenAPI specification and MCP server setup. ## JavaScript example ```javascript import { ApifyClient } from 'apify-client'; // Initialize the ApifyClient with your Apify API token // Replace the '' with your token const client = new ApifyClient({ token: '', }); // Prepare Actor input const input = { "coordinates": [ "48.8566,2.3522", "45.8326,6.8652" ] }; // Run the Actor and wait for it to finish const run = await client.actor("vigilant_jasmine/french-elevation-lookup-ign").call(input); // Fetch and print Actor results from the run's dataset (if any) console.log('Results from dataset'); console.log(`💾 Check your data here: https://console.apify.com/storage/datasets/${run.defaultDatasetId}`); const { items } = await client.dataset(run.defaultDatasetId).listItems(); items.forEach((item) => { console.dir(item); }); // 📚 Want to learn more 📖?
