AGOL nahradit existující data novými daty

Question

<\/HEAD>To může být samozřejmé pro ty z vás, kteří jsou s AGOL více obeznámeni: Vytvořil jsem loni mapu AGOL s 'loňskými daty'. Nyní mám 'tato roční data' Chtěl bych jednoduše nahradit stará novými a zachovat svou symbologii. (Data mají stejná pole jako loni). Kromě mapy jsem vytvořil dashboard. Pokud budu schopen aktualizovat mapu, na kterou se dashboard 'dívá', bude to bezproblémové?<\/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.
