I have uploaded a layer onto the ArcGIS online and collected field data using the collector app. I now want to download or sync the data with my desktop version of Arcma. Is this possible and if so how do I do it? Thanks in advance for any responses.
In ArcGIS Online, you'll want to go to the item details page and export the updated layer to the data format of your choice.
Once this is downloaded to your device, you can pull it into ArcMap. You can then either just incorporate this updated layer into your map, or possibly use the Append tool to join it with the existing layer.
Would this achieve what you're hoping to do? Hope that helps!
