Getting Started with HxDR Catalog

The HxDR catalog follows and implements the STAC specification making Hexagon Geospatial content available and searchable by capture date, location and collection.

Query available collections

A collection is a predefined set of related data which can help you getting started. To start with the HxDR catalog you might like to browse all available collections of data using a graphQL query:

query collections{
  collections
  {
    title
    features(limit: 5000){
      total
    }
    description
    crs
  itemType
  }
}

The response will included content collections such as Basemap_collection or 3DNL. Start by inspecting the collection data in more detail.

query getCatalogFeatureItems
 {
  search(collections: ["basemap_collection"], limit: 10, offset: 0) {
    total
		contents{
			id
			type
			properties{
				title
				referenceToRawOutput
				 data_type
				 format
				 productCode
				 provider
				 srs
				 sensorType
				  referenceToRawOutput
				 detailedGeometry{  bbox}
				 year
				 dateTime
				 startDateTime
				 endDateTime
				layerAddress{
					... on LayerAddressHspc {
						id
						type
						label
						endpoint
						sourceEndpoint
					}
				}

			}
		}
  }
}

This will show the connection details for several context items such as the available sentinel2-cloudless-2018 imagery wms service.
