3 years ago This commit allows user to map ONE band to the <featurecaption>, which admittedly is not too useful, but it's a first step. Thinking about allowing multiple selections in the dropdown choice (which would likely be useful sometimes for vector attributes, too), as well as perhaps a templating mechanism, allowing a formatted string to be included, so the band names would be read in a more user-friendly manner.
Similar to vector feature layers, it should be possible to map a coverage "band", or a concatenation of coverage bands to the
<featurecaption>that is emitted when querying the coverage. Otherwise, coverage data has no accessible name and won't be correctly read to the user. For some types of coverage data, there is only one band e.g. elevation. For other types of coverage there can be more bands and so we should allow the creation of a<featurecaption>from one or more of these (in the case that one band is not meaningful e.g. an RGB value needs all three values to be a color).
