​
Overview

This endpoint allows you to retrieve a specific infrared image using its unique identifier. You can either get the image metadata or download the actual image file.

​
Usage Examples

​
Get Image Metadata

Retrieve metadata for a specific infrared image: 
import requests

response = requests.get(
    f"https://avert-legacy.ldeo.columbia.edu/api/imagery/infrared/r/{image_id}"
)
image_info = response.json()

​
Download Image File

Download the actual infrared image file: 
import requests

response = requests.get(
    f"https://avert-legacy.ldeo.columbia.edu/api/imagery/infrared/r/{image_id}",
    params={"download": True}
)

# Save the image file
with open(f"infrared_image_{image_id}.jpg", "wb") as f:
    f.write(response.content)

​
Batch Download Example

Download multiple infrared images from a query result: 
import requests

# First, get the list of images
query_response = requests.get(
    "https://avert-legacy.ldeo.columbia.edu/api/imagery/infrared/query",
    params={
        "site": "CLNE",
        "vnum": 311240,
        "search_from": "2022-10-01T00:00",
        "search_to": "2022-10-02T00:00"
    }
)

# Then download each image individually
for image in query_response.json():
    print(f"Downloading image: {image['image_id']}")
    image_response = requests.get(
        f"https://avert-legacy.ldeo.columbia.edu/api/imagery/infrared/r/{image['image_id']}",
        params={"download": True}
    )

    with open(f"infrared_{image['image_id']}.jpg", "wb") as f:
        f.write(image_response.content)

​
Notes

  • Image IDs are obtained from the query endpoint response
  • When download=false (default), you get JSON metadata about the image
  • When download=true, you get the binary image file
  • Image file formats vary (JPEG, PNG, etc.) - check the file_format field in metadata
