Is there a way to do an emerging hotspot analysis that illustrates the change in values associated with points or polygons over time as opposed to simply counting the number of points that occur over time?
I am thinking not natively. I wonder if you would need to have an extra attribute that records this change in time and then do the emerging hot spot analysis.
I think I might have the same question. We have data of fire hydrant assessments by several crews over several weeks. They record several different factors about each hydrant such as: Pressure, or length of time it was flowed for. It’s relatively easy to find trends in each of these dimensions like:
But I want some kind of multivariate analysis and the problem with Emerging HotSpots is that they will only assess a single analysis variable at a time (eg: Assessment Count, or ave FLOWTIME, or Std Dev of PRESSURE) and tell me if, over time in that area, that variable goes hot (increases) or cold (decreases), oscillates or is sporadic. What I want is to know if COUNT lowered over time in this AREA as Std Dev of PRESSURE increased. Thoughts?

Hi Jennifer Weaver,
With the Create Space Time Cube By Aggregating Points tool you can add summary fields so that values associated with your points are summarized.
Available statistic types are:
With the Create Space Time Cube From Defined Locations tool you can provide point or polygon data with values at the same location over time and analyze them without spatial aggregation.
Hope this helps,
