O Portal for ArcGIS vem pré-configurado com uma coleção de mapas base do ArcGIS Online. Estes mapas base não são suportados para utilizar em fluxos de trabalhos offline. Por exemplo, você não pode utilizar estes mapas base offline pré-configurados no Collector for ArcGIS.
O seguinte script do python utilizam os mapas base do ArcGIS Online padrão e os adicionam como itens de mapa no seu portal. Os itens de mapa do mapa base podem ser utilizados offline e em fluxos de trabalhos offline. Para executar o script, você precisará fornecer suas credenciais da conta do ArcGIS Online.
Você é solicitado para especificar as seguintes informações ao executar o script:
- URL utilizada para acessar o Portal for ArcGIS. Esta pode ser a URL do ArcGIS Web Adaptor, por exemplo, https://webadaptorhost.domain.com/webadaptorname ou a URL da máquina que hospeda o portal, por exemplo, https://portal.domain.com:7443/arcgis. Você deve incluir o nome de domínio qualificado completo da máquina ao especificar a URL.
- Nome de usuário e senha de uma conta no seu portal.
- O nome de uma pasta onde novos itens de mapa serão criados. Se não fornecido, os itens de mapa são criados na sua pasta raiz.
- Nome de usuário e senha de uma conta do ArcGIS Online. Este script embutirá suas credenciais do ArcGIS Online nos novos itens de mapa, que ativa os recursos offline dos mapas base.
O seguinte exemplo cria uma coleção de mapas base em sua pasta raiz. Os mapas base incluem suas credenciais do ArcGIS Online, então aplicativos como Collector for ArcGIS podem utilizá-las em fluxos de trabalho offline.
