Asset Register

[zyinhls]

Hi Vincent or any experts,

If there are many assets in database, I just want to register three assets. How to put three assets in the below register command?

curl -X 'POST' 'http://127.0.0.1:8081/mosaic/register'
-H 'accept: application/json'
-H 'Content-Type: application/json'
-d '{"collections":["landsat-c2l2-sr"], "bbox":[-123.75,34.30714385628804,-118.125,38.82259097617712], "filter-lang": "cql-json"}' | jq

Thanks.

I can't remember if we can filter the assets directly with the CQL filter
Maybe @bitner knows :-)

Thanks, Vincent.
I use eoAPI-raster-Swagger UI register format with assets B04, B03, B02 (below). It registers without error, but it cannot filter assets and all 12 assets still available. What does assets in metadata mean? What is the difference between bbox and bounds inside metadata?

curl -X 'POST' 'http://0.0.0.0:8082/mosaic/register'
-H 'accept: application/json'
-H 'Content-Type: application/json'
-d '{
"collections":["HLSS30.v2.0"],
"bbox":[-180,-90,180,90],
"filter-lang": "cql-json",
"metadata": {
"type": "mosaic",
"bounds": [
-180,
-90,
180,
90
],
"minzoom": 8,
"maxzoom": 12,
"name": "HLSS30.v2.0",
"assets": [
"B04",
"B03",
"B02"
],
"defaults": {}
}
}' | jq

I see! The assets you added is in the metadata part which is not taken into account by default see #64

What does assets in metadata mean?

The metadata are informative and not used in the endpoints. Please see https://stac-utils.github.io/titiler-pgstac/advanced/metadata/ for more information

What is the difference between bbox and bounds inside metadata?

bbox is part of the pgstac filter, bounds is part of the metadata

I'm also not quite sure what you are trying to do.

• do you want the tile endpoint to default to a combination of the 3 assets (B04,B03,B02)?
• do you want users to only be able to create combination between those 3 assets (adding asset filters in the CQL query)

Thank you for metadata information. For example, in register, we can use bbox and datetime to filter data. Can we filter assets when register? If there are 10 assets: a1, a2, a3, a4... a10. Can we register to filter to 3 assets like a2, a3, a4 (not use other assets)? If that, maybe it will be faster.
