Como atualizar camadas de feição hospedadas corretamente?

Question

<\/HEAD>Estou tentando atualizar uma camada de feição hospedada via um arquivo zip contendo arquivos shape alterados. Embora a atualização seja executada corretamente, o resultado é que as feições são apenas duplicadas em vez de realmente alteradas?<\/P> <\/P> Alguma sugestão sobre por que isso acontece? Fundamentalmente, quero uma camada de feição hospedada que eu possa atualizar frequentemente sem a necessidade de gerar e enviar novas camadas de feição toda vez.<\/P><\/BODY><\/HTML>

Hello Ben,

Could you provide some more information as to the workflow you're using? Are you going to the Item Details page of your data and clicking Append? If yes, this process looks for a unique identifier field and uses that to identify data that needs to be overwritten vs. added as new features.

The following page has a run-down of this workflow:

Manage hosted feature layers—ArcGIS Online Help | ArcGIS

You can set one of your fields as a Unique Identifier by going to the Data page (top right of the Item Details page), then going to Fields in the top right, selecting the field in question, and changing the Field Value Type to Unique Identifier. Then try appending again and it should overwrite matching unique identifier features.

Let me know if I need to clarify more, not sure if that's clear. Thanks!

Best regards,

Rachel
