The spatial-temporal cube of ArcGis : 2- Hot and Cold Spots

In the previous article (Le Cube spatio-temporel d’ArcGis : 1- découverte) we discussed how to create a spatial-temporal cube from a cloud of XYZ points.

  The points are grouped into ” boxes ” (bins) corresponding to 3D pixels.
We have discussed how to depict them in an ArcGis Pro 3D scene. In this article we will discuss how to analyze the temporal trends of the bins values, using the analysis of emerging hot spots. Continue reading “The spatial-temporal cube of ArcGis : 2- Hot and Cold Spots”

The spatial-temporal cube of ArcGis : 1- discovery

One of the domains of GIS where still remains a lot to be done is the field of temporal analysis  . While almost all the available tools focus on the spatial evolution of a phenomenon, we are left helpless when trying to visualize or analyse a phenomenon that changes as a function of time as well.

For some time, we have the support of animation tools that allow us to see a sequence of maps and perceive the change over time. Regardless of how useful they are for communication, they are useless to perform a serious data analysis. In this series of articles, we will discuss new  ArcMap and ArcGis Pro tools available  in the form of a Toolkit Tools model for the  spatial-temporal exploration (Time Pattern Mining). An example has been selected in order to process, at first with ArcGis Pro, and, later, with ArcMap.
