Is it possible to use our Titiler with COG hosted by others providers?

[WCMC-vblanque]

Hi all,

Thanks for the amazing stuff achieved by Titiler.

A bit of context, we would like to pull data from different providers (i.e. Planetary Computer, NASA, Element84...) some are protected with credentials (AWS, Azure, GCS) and other are public with "Requester Pays"=FALSE.

1. (a) Is it possible to have only one TiTiler to work with different providers or we will have to deploy as many Titiler instances as provider we want to be connected with?
   In particular, I did not succeed to connect our Titiler and pull the data referenced in this STAC collection:
   https://earth-search.aws.element84.com/v1/collections/cop-dem-glo-30 It looks like I need to inform AWS_NO_SIGN_REQUEST=YES.
   (b) Can we pass this configuration as parameter to Titiler?
   (c) Is there a good documentation to connect Titiler to external data?

2. Also I can imagine that if the provider offers a Tiler endpoint we can use it like Planetary Computer (https://planetarycomputer.microsoft.com/api/data/v1/) but how to get informed the Tiler URL from different provider?

@vincentsarago Any idea how to do that?

Thanks in advance.

Vincent

You need to make sure to allow the copernicus-dem-30m bucket on your AWS deployment

titiler/deployment/aws/cdk/config.py

Lines 32 to 36 in c01062f

	# S3 bucket names where TiTiler could do HEAD and GET Requests
	# specific private and public buckets MUST be added if you want to use s3:// urls
	# You can whitelist all bucket by setting `*`.
	# ref: https://docs.aws.amazon.com/AmazonS3/latest/userguide/s3-arn-format.html
	buckets: List = []

Is there a good documentation to connect Titiler to external data?

usually rely on GDAL documentation

Hi Vincent,
Thanks for your reply and all the amazing work you are doing.
Our deployment of Titiler is currently on MS Azure (not AWS), is there any other parameter we will have to configure?
I have also seen the Titiler+CMR which will be very useful to pull in HDF data.
Bon weekend.
