STAC API Query Example

Demonstrates querying a STAC (SpatioTemporal Asset Catalog) API endpoint:

node examples/stac-query.js

This example shows how to:

• Connect to a STAC API endpoint
• Retrieve endpoint information and capabilities
• List all available collections
• Get detailed collection metadata (extent, providers, license, etc.)
• Query items with various filters:
  • Limit (pagination)
  • Bounding box (spatial filtering)
  • DateTime (temporal filtering)
• Retrieve a single item
• Build custom query URLs

The example queries the public STAC API at:

• https://api.stac.teledetection.fr
• https://catalog.maap.eo.esa.int/catalogue
• https://stac.dataspace.copernicus.eu/v1/
