Claim:
1. A pattern-retaining method for allocating large volumes of geographic data points to regionation level data sets for providing displays of data points at user controlled zoom levels that are representative of the data distribution and density comprising: determining the desired number of data cells; retrieving a requested data set; randomly selecting from the requested data set one data point from each cell that contains at least one data point to represent that cell and placing the selected data points in location handled data set S removing the data points in location handled data set S placing the remaining data points from the requested data set in density handled data set S allocating data points from location handled data set S creating a table of N regionation levels and specifying the number of data points to be placed in each regionation level and; creating regionation levels 1 through N by repeating the following steps:
