DEFINITION

What is a Density Grid?

A density grid is a way to visualize and analyze point data by transforming the points into a regular grid. Each resulting grid cell is assigned a value that is determined by the density of nearby points, optionally weighting each point using a weighting value.

Density grids are useful for mapping crime data to show hot spot locations, mapping vehicle miles traveled to spot areas of congestion and higher air pollution, and analyzing the pattern of clients around a store weighted by the cost of their purchases.
