The goal of the application is to quickly generate maps in order to do summary analysis on a data set. The application leverages OLAP technology to quickly perform the summary analysis then generates a map to reflect the analysis. An example of summary analysis could be to calculate the number of precipitation observation measurements during the decade of the 1990s for each state. Each query submitted has a spatial component, and the results of the query are displayed by coloring the spatial extent based on the results of the query. The result is a choropleth map.
Here is a link to a STORET instance of the map making application.
