An overview of the Space Time Pattern Mining toolbox

The Space Time Pattern Mining toolbox contains statistical tools for analyzing data distributions and patterns in the context of both space and time. The toolbox contains two tools: Create Space Time Cube and Emerging Hot Spot Analysis.

Create Space Time Cube takes point datasets and builds a multidimensional cube data structure (netCDF) for analysis. Emerging Hot Spot Analysis then takes the cube as input and identifies statistically significant hot and cold spot trends over time. You might use Emerging Hot Spot Analysis to analyze crime or disease outbreak data in order to locate new, intensifying, persistent, or sporadic hot spot patterns at different time-step intervals.

Note:

An accompanying sample script utilities toolbox for use with ArcGIS Pro is available for download at www.esriurl.com/SpaceTimeCubeUtilitieswhich includes tools for visualizing your cube data in 2D and 3D. These tools can be used to understand the structure of the cube, how the cube aggregation process works, and also to visualize the patterns over time at specific locations of interest. See Visualizing the Space Time Cube to get strategies allowing you to look at cube contents.

Tool	Description
Create Space Time Cube	This tool summarizes a set of points into a netCDF data structure by aggregating them into space-time bins. The points are counted within each bin, and for all locations, the trend for counts over time are evaluated.
Emerging Hot Spot Analysis	This tool identifies trends in the clustering of space-time point data, including new, intensifying, diminishing, and sporadic hot and cold spots.
