Getting Started with HxDR Catalog
The HxDR catalog follows and implements the STAC specification (opens in a new tab) 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.
