Is there a way to find the mean center of a group of point features in ArcGIS Online?

Answer

The Mean Center tool is only available in ArcGIS Desktop applications, and there is no equivalent tool to find the mean center for simple point features in ArcGIS Online. However, there is a way to find the mean center of a group of point features in ArcGIS Online. The Find Centroid tool in ArcGIS Online is similar to the Mean Center tool in ArcGIS Desktop. When finding the mean center of a group of points, the Find Centroid tool only takes multipoint features as input.

To find the mean center using the Find Centroid tool in ArcGIS Online, follow the steps below:

1. Use the Dissolve tool in ArcMap or ArcGIS Pro to create a multipoint feature out of the original point feature class.
2. Publish the output of the Dissolve tool to ArcGIS Online, and use the Find Centroid tool to obtain the mean center. For more information on the Find Centroid tool, refer to: Find Centroids

Note:
If the at the true centroid option is checked, a new point is created based on the x and y coordinates of all the points in the multipoint feature. If the contained by input features option is checked, the output centroid created is coincident to one of the points in the multipoint feature.
