AGOL 既存のデータを新しいデータに置き換える

Question

<\/HEAD>AGOL に詳しい方には当たり前かもしれませんが：私は昨年「昨年のデータ」で AGOL マップを作成しました。今、「今年のデータ」があります。シンボルはそのままに、古いデータを新しいデータに単純に置き換えたいと思っています。（データは昨年と同じフィールドを持っています）。マップに加えて、ダッシュボードも作成しました。もしマップを更新できれば、そのマップを参照しているダッシュボードもシームレスに更新されますか？ <\/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.
