HI Dan, great resources, thanks for sharing!

It seems that the blogpost https://community.esri.com/groups/dan-patterson-test/blog/2016/01/01/circular-mean-for-directional-d... is not open for public access.

[DanPatterson_Retired]

Thanks Xander, I will fix it and update the link.

Had to repost. The link in the above listing has been corrected.

The new direct link is Circular mean for directional data

[XanderBakker]

Yep, it's working now. Thanx!

[SimonKettle]

Hi Dan, This is a great resource! Thanks for all your efforts!!!

Cheers,

Simon

Dan, just noticed this tool when looking thru the help for something else.  You should add it to you links re: Desktop to Pro help, if it isn't there already.  I have not tested yet but looks promising.

Analyze Tools For Pro—Help | ArcGIS for Desktop   10.3

Analyze Tools For Pro—Help | ArcGIS for Desktop   10.4

Summary

Analyzes Python scripts and custom geoprocessing tools and toolboxes for functionality that is not supported in ArcGIS Pro.

There are differences between ArcGIS Pro and ArcGIS 10.x that may mean changes to some custom tools and scripts so they run successfully in ArcGIS Pro. These changes include geoprocessing tools and environments that are not supported in ArcGIS Pro, the replacement of the arcpy.mapping module with the arcpy.mp module, unsupported data formats (such as a personal geodatabase), and an upgrade to Python 3.4 from Python 2.7.

Thanks Rebecca, I will have a look for sure, especially to see how the checks for python 3.4+ went.
