A heat map (or density grid) is used 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 proximity of nearby points, optionally weighting each point using a weighting value. Heat maps use color palettes that represent the values from low to high. Unlike a choropleth map, a heat map does not conform to geographic locations such as states, counties, postal codes, or land parcels.
Heat maps 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.
