What is heat map in vMAP?

Heat maps are used to visualise areas that have different densities of spatial entities on the map. The vMAP Heat map can be used to visualise geographic data which is generated with different colors to show where higher density areas occurs. It helps convey the relationship between values in an accessible way. For example, you can create a heat map to show the density of households. The areas with more households will have a darker color and the areas with fewer households will a brighter color. By looking at the heat map, you would be able to quickly tell which areas have more households.
