Ability to filter STAC data by COGs

[heidimok]

• stac ipyleaflet version: for release 0.3.0
• Python version: python >= 3.9 (some of the widgets are incompatible at v 3.8)
• Reference column Number 16 in the MAAP-ipyleaflet-DevRoadmap

Context

Release 0.2.0 of stac_ipyleaflet allows users to select a collection from the STAC data catalog.

Problem

Many of the collections don't have COGs, and as a result won't have anything visual to display on the map. It can be frustrating to click around without knowing which collections will have a visual output.

Acceptance Criteria

• UI that allows users to filter STAC data catalog by items that actually have something visual (COGS) to display on map

It could also be an option to filter non-compatible Collections by default. Will need to look at the metadata at the Collections level - it would be optimal to know the Collection's Items formats, without having to query for the items.

I will be taking this ticket to get started

Just contributing some ideas from a UI perspective we can all talk through more.

Question - is the filter at the collections level or the items level?

• Collections level:

• Items level: or another possibility is a toggle by the title

Question - is the filter at the collections level or the items level?

I believe it's both, although what's missing in the current build is at the Collections level.

This is reading from the item_assets property on the selected Catalog Collection.
