3 weeks ago I just noticed that #28 duplicates some of the request in this ticket, mainly for WMTSCapabilities that is discussed extensively there. As displaying STAC catalogs is also a good idea, I will leave this ticket open to address STAC, and we can address WMTS in #28
The workflow-generated imagery layers would benefit from the addition of a metadata document to enhance their accessibility and reusability. This document could be incorporated into an ADC data package along with the tile files. It could also be used to provide instructions for map tools on how to render the data.
A few potential formats have been identified:
WMTSCapabilities Document: This document offers an overview of the server capabilities and metadata about the dataset, and while Cesium doesn't seem to support it, several other significant map tools (e.g., QGIS, ESRI) do. We could potentially add our own method in MetacatUI to parse a WMTSCapabilities doc and use it the configure a layer in the map.
STAC Metadata: The SpatioTemporal Asset Catalog (STAC) provides a standardized way to describe geospatial assets, which could facilitate discovery and reuse of our datasets.
We may also want to explore the potential of using other metadata formats.
The goal of this issue is to investigate metadata formats specific to geospatial assets, to decide on the most appropriate format(s) to use, and to create a mechanism that automates the creation of these metadata for future datasets.
