mosaic map endpoint help

[hrodmn]

I have a mosaic searchid registered (one collection, no bounding box or datetime filter) and can load the XYZ tiles into QGIS or a Leaflet map, but the map endpoint doesn't seem to be behaving for me. Am I using it wrong? When I open it I get a mostly blank map canvas:

Here is what my map endpoint url looks like for a composite of three assets:
{raster_endpoint}/mosaic/{searchid}/map?assets=120&assets=900&assets=800&rescale=0,0.6&rescale=0,0.6&rescale=0,0.6

The XYZ tile url that works:
{raster_endpoint}/mosaic/{searchid|/tiles/WebMercatorQuad/{z}/{x}/{y}@1x?assets=120&assets=900&assets=800&rescale=0,0.6&rescale=0,0.6&rescale=0,0.6

• is there any logs in the frontend?
• is the endpoint local or deployed?
• maybe there is a IAM role issue (maybe the data is not available to the tiler)
• if the data is not in one of your bucket (or not in the same region), the tiler won't have access to it (update Subnets #60)

The problem with mosaic is usually the zoom definition, it might be wise to set the min/max zoom in the mosaic metadata or in the tilejson call

I fired up a local docker network pointing at the deployed database and got some actual error logs:

The tile index is weird 🤔 , maybe the bbox in the mosaic is wrong!

[hrodmn]

I think it wasn't working because I did not set a value for bbox when I registered the searchid. A new searchid with bbox set correctly fixes the problem. Maybe we could add a default bbox=[-180, -90, 180, 90] at some point upstream?

🤔 there should be a default bbox https://github.com/stac-utils/titiler-pgstac/blob/main/titiler/pgstac/factory.py#L408-L411
