Hi All,
I am performing an emerging hotspot analysis in ArcPro on my 14-year data. The space-time cube was created by aggregating data onto 1-year interval and using defined locations. After performing the emerging hotspot analysis, I used Visualize Space-Time Cube in 3D to display Hot and cold spot results year by year. I found the results did not match the hotspot pattern I got by running a separate HotSpot analysis on the same-year data, although the values are the same.
I was wondering whether I got something wrong here. Any advice? Thanks!
screen grabs of what you are referring to would help visualize
So when you say that the results of the Emerging Hot Spot Analysis didn't match those of Hot Spot Analysis (Getis-Ord G* ?), you just mean the symbology, right? Because the values are the same.
That makes sense because Hot Spot Analysis is symbolizing z score and p values at one time (a single time slice of a space time cube):
And when you visualize the space time cube through running Emerging Hot Spot Analysis, the symbology is representing the change over time.

Note how the symbols represent a comparison over time:
I'm not an expert in this realm, but I think this describes what you're seeing.
