By popular demand we have published a blog post outlining a workflow to create track heat maps using GeoAnalytics Desktop tools in ArcGIS Pro. Check out the blog and try the workflow for yourself using the provided sample script and data, here: Track Heat Mapping with GeoAnalytics Desktop tools
Spoiler alert! Here's a quick GIF from the blog that demonstrates how effective the workflow is in visualizing and uncovering patterns in track datasets:
I'm excited to hear any feedback about this workflow and if it was able to help you complete your track analysis workflows.
The blog contains a link to a sample notebook that you can modify to use with your own GeoAnalytics Server, as well as instructions on how to run this through REST. This functionality exposes capabilities of the spatiotemporal big data store that is also used with GeoEvent Server.
