Is your feature request related to a problem? Please describe.
The goal is to improve the user experience when browsing collections containing coverages. As a user, I would like to see a preview of what the coverage contains instead of just its bounding box.
Describe the solution you'd like
The proposal is to add a field to the configuration of coverages: either thumbnail or preview or overview, like e.g.:
providers:
- type: coveragename: rasteriodata: data/stuff.tifthumbnail: auto
For (very) large datasets, generating a thumbnail/overview might be troublesome, and data providers might already have overview images, so it might be also possible to think of something like:
thumbnail: data/stuff-preview.png
Additionally to the thumbnail/overview generation, it should be displayed in the collection/coverage webpages when browsing - that means a bit of Leaflet work.
Describe alternatives you've considered
Assuming that the coverage is a GeoTIFF, fetching the overview (or the 0-th image in the file) is not a viable solution because of the lack of HTTP range requests.
