eoAPI_Maxar_demo: raster endpoint

[nsshah1288]

Hi, thank you so much for the demo located here: https://github.com/developmentseed/eoAPI/blob/main/demo/Maxar/eoAPI_Maxar_demo.ipynb

it is very helpful!

One small comment, when I was doing the Asset visualization, when I did info = httpx.get(f"{raster_endpoint}/collections/{collection_id}/items/{item_id}/info").json() , I was getting the following error:
{
"detail": "AWS_SECRET_ACCESS_KEY and AWS_NO_SIGN_REQUEST configuration options not defined, and /root/.aws/credentials not filled"
}

In the docker-compose.yml file here, I removed the AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY environment variables from titiler-pgstac and added AWS_NO_SIGN_REQUEST=true. Then, the raster endpoint worked to return the metadata for the assets.

Thank you again for the demo!

one more thing I forgot, the paging to get all the items was not working for me. I think it was not properly hitting the next link and therefore was requesting the same set of items over and over again.

I changed the cell to look like the following, using a counter:

kahramanmaras_items = []

url = f"{stac_endpoint}/collections/{collection_id}/items"
x = 0
while True:
    if x == 0:
        items = httpx.get(url, params={"limit": 100}).json()
    else:
        items = httpx.get(url).json()
    
    kahramanmaras_items.extend(items["features"])
    next_link = list(filter(lambda link: link["rel"] == "next", items["links"]))
    if next_link:
        url = next_link[0]["href"]
        print(url)
    else:
        break
    x += 1    

print(f"Nb Items: {len(kahramanmaras_items)}")

and then it worked and returned 2115 items. I will make a small PR for this if I get some time
