Hi @Smaran
To visualize data using the built-in Explorer, you must have the following elements of your STAC Collection set-
The item_assets field in the STAC Collection JSON must be set. Setting this field establishes the key-value pair that is mandatory for the tiler to understand where the data to visualize is located.
- The render configuration must also be setup to tell the tiling system how to visualize the data.
