AGOL substituir dados existentes por novos dados

Question

<\/HEAD>Isso pode ser óbvio para aqueles de vocês mais familiarizados com AGOL: Eu criei um mapa AGOL no ano passado com 'dados do ano passado'. Agora eu tenho 'dados deste ano' Eu gostaria de simplesmente substituir os antigos pelos novos, mantendo minha simbologia. (Os dados têm os mesmos campos do ano passado). Além do mapa, eu criei um painel de controle. Se eu conseguir atualizar o mapa que o painel 'visualiza', será que será transparente?<\/P><\/BODY><\/HTML>

I fiddled around a bit and added the new data to the original map and did a 'save as' to 'this-years-map'  Turns out the data is a little more dyanmic year to year than I thought.  I did look at the append and overwrite options as shown in the suggested help files.

Thanks for the suggestions!

Can you also still follow the suggestion in this thread by editing the layer within Arcmap and then posting the updates back to the hosted layer?

Hi Joe,

I'd suggest either overwriting the feature layer with the new data like Katie suggested or using the append tool to add the new data to the existing dataset while filtering out your previous years data. Web maps and dashboards read the data and symbology from the item (layer item) and from the services url. If you use either overwrite or append, the itemID and service url remain the same, enabling a seamless transition once the underlying data is updated. The method you choose will really depend on the data that you want to store in ArcGIS Online, one year or multiple years.
