Calling Google API for elevation data using python 3

[vijesh (VIJESH KUMAR V)]

Hi all,

I am trying to retrieve the elevation data of a specific lat-long using python code in grasshopper-ghpython 3. I have tried it in vscode and it is working with package requests.

Thanks in advance

I think this is the solution.

GoogleMaps API

ShapeDiver supports the Swiftlet plugin, which lets you make requests to REST APIs directly from within Grasshopper. As a matter of fact, we have been thinking of putting together an example using Google APIs, but in any case you can read all the documentation and examples provided with Swiftlet which give a good introduction.

[Martijn.w (Martijn Weiland)]

As a substitute of the requests module you could use the urllib.requests module

import urllib.request

def get_elevation(lat, lon):
    url = f"https://api.opentopodata.org/v1/test-dataset?locations={lat},{lon}"
    res = urllib.request.urlopen(url)

if __name__ == "__main__":
    get_elevation(lat=37.7749, lon=-122.4194)

Result:

{
    "results": [
        {
            "dataset": "test-dataset",
            "elevation": -142.42425537109375,
            "location": {
                "lat": 37.7749,
                "lng": -122.4194
            }
        }
    ],
    "status": "OK"
}
