HTTP Response

The above commands returns the following JSON with task status

{
    "status": "status",
    "task_id": "task_id",
    "req_id": "req_id",
    "task_timeout": task_timeout
}

After that, you need to send a request for checking task status using task_id

Example: Download image of the NDVI from Sentinel2 from the AOI

Step 1: Create task for index caclulating with POST request

curl --location --request POST 'https://api-connect.eos.com/api/gdw/api' \
--data '{
    "type": "jpeg",
    "params": {
            "view_id": "S2/13/R/EL/2023/7/19/0",
            "bm_type": "NDVI",
            "geometry":{"type": "Polygon",
                    "coordinates": [
                        [
                            [-104.87931347024973, 27.166227117387663],
                            [-104.87190853064376,27.17371136921598],
                            [-104.87486446023671,27.175686643908065],
                            [-104.87271173924485,27.178599422270565],

                            [-104.88103048496039,27.176643443128853],
                            [-104.87771956045358,27.172771682872458],
                            [-104.88236756436531,27.17042134807906],

                            ]
                        ]
                      },
        "px_size": 4,        
        "format":"png",
         "colormap": "a9bc6eceeef2a13bb88a7f641dca3aa0",
        "levels": "-1.0,1.0",
        "reference": "ref_datetime",
        "calibrate": 1
    }
}'

Step 2: Receive the result of calculation with GET request and use task_id from previous step

curl --location --request GET 'https://api-connect.eos.com/api/gdw/api/5144aaff-f442-4b18-b20f-7c239ac15a3f' \
--header 'x-api-key: <your_api_key>'

Custom colormap

You can create custom colormap with Colormap endpoint
