Getis-Ord (Gi*) Hot Spot

Getis-Ord (Gi*) allows you to assemble a hot spot map based on statistical confidence. This kind of hot spot map is useful in crime analysis; it can be particularly efficient when querying small areas.

Getis-Ord hot spots can highlight significant clusters that are both hot and cold (i.e. areas with particularly high incidence and particularly low incidence). This is in stark contrast to KDE which can only highlight hot spots.

Select Analysis > Hot Spot > start the Hot Spot wizard.

TIP: We recommend initially running the analysis several times altering settings and styling so the created Grid is optimized for its purpose.

If the Grid is stored within an internal overlay, you can find it under 3D as Grid:
