I'm working on a project in ArcPro 2.3 that has multiple independent feature layers, as in over 50, that need to be combined into one working feature layer. At the moment, each layer is a simple hand-drawn polygon. The polygons all regard the same category of data so I would ideally like to have the layers combined for easier processing, as well as all attribute data into one table. I plan to eventually join a data set to the combined attribute table, hence the need for the feature layers to all be on one layer.
Anyway, does anyone know of a tool or workflow that I could go about for combining the large amount of feature layers into one layer?
Apologies if this is unclear.
ArcGIS Online has the Merge Layers tool, which sounds like it may work for you.
Since you mentioned you are working in Pro, you could use the Merge tool but you would first have to export all existing data to file geodatabases, and use the resulting feature classes as inputs since the tool doesn't take feature layers as inputs.
I hope this helps a little!
