Aggregation is summing numeric values to a larger geographic feature from a smaller feature. It is common to have a map layer, such as ZIP Codes, that contains data such as population, number of customers, or sales amounts. You can use mapping software to get the population, number of customers, or total sales for a sales territory, a county, or a whole state by aggregating the values from the ZIP Codes that the larger features comprise.
