Download Collection Image in a Zip Format Issue

Hi, I am aimed to download all existing image in a collection with zip archive for planet scope images but the code returns invalid collection type.

error message: Failed to download data: 400

When specifying your collection ID for PlanetScope data, make sure you declare it as a BYOC collection (see documentation here):

 "data": [
            {
                "type": "byoc-8c3ff934-5cf2-253b-f54c-5bgb044f7dbe",  # Replace with the correct collection ID for PlanetScope data
                "dataFilter": {...

I did but still the same error returns:

The error you are getting is different:

The system is telling you, that you cannot directly return zip format: we only support jpeg, png, tiff, json, or zarr.

Either you can return the data in one of the above formats and zip them in a second step, or use the direct download functions as specified in the documentation here: Third Party Data Import API .

Hi,

as the error message states, it cannot evaluate the evalscript. I can’t see it in your code block so can you please share that here so we can help debug it.

There is no Evalscript in your request so it will not work. In this script you need to define your inputs, processing and outputs.

You can find some examples for this with Planetscope data here.
