Is it possible to Publish from Arc Pro two Polygon shapes as a single hosted feature layer to Arc Online
Without merging them first
Do you mean two polygon feature classes as a single web feature layer? Or two polygons in a single feature class as a multipart polygon as a single web feature layer?
Two polygon features (keeping their attributes) into a single feature class as a multipart polygon as a single web feature layer?
Ideally without having to Merge. (which requires additional geo-processing steps and ungroup prior to publishing)
While it is possible to publish a single web feature layer with multiple feature classes, there wouldn't be a way to combine those multiple feature classes into a single feature class with some type of geoprocessing beforehand to combine the data. If the final goal is the combine both polygons into a single multipart polygon, then the Merge would need to be used.
That would seem to be the case. I shall pursue.
One way round was to use the merge tool pencil symbol > to draw a series of polygons and then merge these with an existing one – then all would be saved as a single layer.
Thanks for the response.
Most probably merging them first will be the easiest way to accomplish what you want.
An alternative would be to publish one first and then append the second one to it.
