mosaicJSON path

Every method to cogeo-mosaic-tiler accepts a url parameter, which allows for describing the path to the MosaicJSON, and further allows using different backends, such as an internet URL over HTTP, a file on S3, or a DynamoDB table.

https://{endpoint-url}/{method}?url={mosaicURL}

For example:

S3:
- https://{endpoint-url}/{method}?url=s3://{bucket}/{key}
HTTP:
- https://{endpoint-url}/{method}?url=http(s)://example.com/path/to/mosaic
DynamoDB. If you don't pass a region, the local region is assumed. Note that if you don't pass a region you need three ///.
- https://{endpoint-url}/{method}?url=dynamodb://{AWS region}/{mosaicid}
- https://{endpoint-url}/{method}?url=dynamodb:///{mosaicid}
Local file. Note if you pass file:/// you need three ///.
- https://{endpoint-url}/{method}?url=file:///path/to/local/file
- https://{endpoint-url}/{method}?url=/path/to/local/file
- https://{endpoint-url}/{method}?url=./relative/path/to/local/file
- https://{endpoint-url}/{method}?url=relative/path/to/local/file

Historically, a mosaicid is a 56-character hexadecimal string (matching [0-9A-Fa-f]{56} regex), usually created using sha224sum mymosaic.json.gz.

$ cogeo-mosaic create mylist.txt -o mosaic.json.gz

$ sha224sum mosaic.json.gz
92979ccd7d443ff826e493e4af707220ba77f16def6f15db86141ba8  mosaic.json.gz

Using mosaicid

Most of the GET requests support using mosaicid in the path (prefix) instead of passing an url. When using mosaicid, the tiler will reconscruct a file s3 url and then result to s3://{bucket}/mosaics/mosaicid.json.gz, with {bucket} set in the environment variable.

def _create_mosaic_path(
    mosaicid: str,
    bucket: str = os.environ["MOSAIC_DEF_BUCKET"],
    prefix: str = os.environ.get("MOSAIC_PREFIX", "mosaics"),
) -> str:
    """Translate mosaicid to s3 path."""
    key = f"{prefix}/{mosaicid}.json.gz" if prefix else f"{mosaicid}.json.gz"
    return f"s3://{bucket}/{key}"

Example

$ curl https://{endpoint-url}/92979ccd7d443ff826e493e4af707220ba77f16def6f15db86141ba8/info

will give the same result as

$ curl https://{endpoint-url}/info?url=s3://{bucket}/mosaics/92979ccd7d443ff826e493e4af707220ba77f16def6f15db86141ba8.json.gz
