Basic Tools / Data Access

This application acts as a primer to working with the ArcView / Avenue API.

avenue API

Three items were developed, and described below:


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


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.

skew algorithm


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

skew algorithm applied to selection tool

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.
