Overview of this book

This book is ideal for Python programmers who are tasked with or wish to make a special-purpose GIS application. Analysts, political scientists, geographers, and GIS specialists seeking a creative platform to experiment with cutting-edge spatial analysis, but who are still only beginners in Python, will also find this book beneficial. Familiarity with Tkinter application development in Python is preferable but not mandatory.

In this chapter, we built the core foundation of our application. In each of our vector and raster folders, we created three new modules that allow us to access, edit, and share some popular geographic data formats. Our folder structure should, therefore, look something like this:

Summary

This is the minimum we will need for any type of GIS application. We can theoretically, at this point, make a minimalistic application focused only on loading and handling file formats. In the next chapter, we jump straight into making the visual interface application, so we can have a real interactive application up and running as soon as possible.
