Help in getting elevation GEOTiff using Earth Engine API

[monkeybanana1024]

Hi,
I am trying to get a rather large amount of elevation GEOTiffs using the earth engine api. Sadly, my code is returning corrupted or incorrectly encoded GEOTiff files. So I cannot view them in Windows Photo Viewer, nor Google Earth Pro.
Here is my code

import ee
import requests
import os

# Initialize the Earth Engine module
ee.Initialize(project='my-project-id')

# Function to read coordinates from a file
def read_coordinates(file_path):
    with open(file_path, 'r') as file:
        lines = file.readlines()
        # Assuming the file contains one coordinate pair per line in "lat,lon" format
        coordinates = [tuple(map(float, line.strip().split(','))) for line in lines]
    return coordinates

# Function to download the elevation data using Copernicus DEM
def download_elevation_data(lat, lon, line_count):
    # Create a point from the coordinates
    point = ee.Geometry.Point(lon, lat)

    # Define a 1 mile x 1 mile square around the point
    buffer_distance = 804.67  # Half of 1 mile in meters
    roi = point.buffer(buffer_distance).bounds()

    # Load the Copernicus Digital Elevation Model (DEM) as an ImageCollection
    copernicus_dem = ee.ImageCollection("COPERNICUS/DEM/GLO30")

    # Apply the .max() reducer to get the maximum value of each pixel across all images in the collection
    max_elevation_data = copernicus_dem.median().clip(roi)

    # Generate a download URL for the image (GeoTIFF format)
    download_url = max_elevation_data.getDownloadURL({
        'scale': 30,  # Scale in meters
        'region': roi.getInfo()['coordinates'],
        'format': 'GeoTIFF'
    })

    # Download the GeoTIFF file
    response = requests.get(download_url)

    if response.status_code == 200:
        # Make sure the subfolder exists for saving the file
        folder_path = f'Test/{line_count}'
        os.makedirs(folder_path, exist_ok=True)
        
        # Save the file locally with a unique name based on coordinates
        filename = os.path.join(folder_path, f'topo_{lat}_{lon}.tif')
        with open(filename, 'wb') as f:
            f.write(response.content)
        print(f'Downloaded: {filename}')
    else:
        print(f'Failed to download data for coordinates: {lat}, {lon}. Status code: {response.status_code}')

# Read coordinates from the specified file
coordinates = read_coordinates('coordinates.txt')
line_count = 1

# Loop through each coordinate pair and process elevation data
for lat, lon in coordinates:
    print(f"Processing coordinates: {lat}, {lon}")
    download_elevation_data(lat, lon, line_count)
    line_count += 1

Could you all please help me? I need this code for a research project, and I'm in a tight schedule so I would really appreciate a quick response!
Thanks a lot,
Arnav
