Pattern-retaining Method for Displaying Large Volumes of Geographic Based Data Using Statistical Depopulation

摘要

Disclosed herein are various embodiments of a method for graphically displaying large volumes of data points on a display in an intuitive and readily understandable manner using statistical depopulation by defining multiple regionation levels using a combination of location based data and density based data with a random selection process to add more data points as more detail is requested while retaining the same overall pattern as when all points are displayed. Also disclosed are various embodiments for using the geographic bounds of a screen display to determine the appropriate level of data to display. The embodiments described ensure that the user is not overwhelmed by too much data on screen for areas with multiple data points, while ensuring that areas with few data points are also represented on the display.
