Three items were developed, and described below:

ThemeAdd

This button opens a shapefile, renames it and joins it to another shapefile, then giving the user a choice to open additional shapefiles.

QuerySkew

This button displays a GUI-based query tool, and saves the resulting selection to a shapefile. The derived shapefile is then tested for a skewness in the distribution, based on a user-entered (numeric) field.

GeoSelectTool

This tool item acts as a region select based on a user-defined selection box, The QuerySkew tool is then applied to the selection.

This application was designed to work with a specific dataset, however the code is as generic as possible. You may use it as you wish.
