예: 오프라인 워크플로에서 사용하도록 Esri 베이스맵 준비

Portal for ArcGIS는 ArcGIS Online에서 베이스맵 컬렉션으로 미리 구성되어 있습니다. 이 베이스맵은 오프라인 워크플로에서 사용하도록 지원되지 않습니다. 예를 들어 Collector for ArcGIS에서 이러한 미리 구성된 베이스맵을 오프라인으로 가져올 수 없습니다.

다음 Python 스크립트가 기본 ArcGIS Online 베이스맵을 가지고 와서 포털의 맵 항목으로 추가합니다. 베이스맵 맵 항목은 오프라인으로 가져올 수 있고 오프라인 워크플로에서 사용할 수 있습니다. 스크립트를 실행하려면 ArcGIS Online 계정 자격 증명을 제공해야 합니다.

스크립트를 실행할 때 다음과 같은 정보를 지정해야 합니다.

  • Portal for ArcGIS 접근에 사용되는 URL. 이는 ArcGIS Web Adaptor URL(예: https://webadaptorhost.domain.com/webadaptorname) 또는 포털을 호스팅하는 머신의 URL(예: https://portal.domain.com:7443/arcgis)이 될 수 있습니다. URL을 지정할 때 머신의 정규화된 도메인 이름을 포함해야 합니다.
  • 포털 계정의 사용자 이름과 비밀번호
  • 새로운 맵 항목이 생성될 폴더의 이름 이 정보를 제공하지 않으면 맵 항목이 루트 폴더에 생성됩니다.
  • ArcGIS Online 계정의 사용자 이름과 비밀번호. 이 스크립트는 ArcGIS Online 자격 증명을 새로운 맵 항목으로 임베드하며, 이를 통해 베이스맵의 오프라인 기능이 활성화됩니다.

다음 예에서는 루트 폴더에 베이스맵 컬렉션을 생성합니다. Collector for ArcGIS 같은 응용프로그램을 오프라인 워크플로에서 사용할 수 있도록 베이스맵이 ArcGIS Online 자격 증명을 포함하고 있습니다.
