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.

Chapter 5. Managing and Organizing Geographic Data

Now that we have an up-and-running explorative application, we can move on to developing some more day-to-day practical features. A common task for users of geographic data is to prepare, clean, restructure, and organize data. In this chapter, you will do the following:

  • Create a window for inspecting the basic properties of each layer
  • Build some convenience functions for commonly needed management tasks, and later add them to the user interface. These functions are as follows:
    • Operations on individual layers being available when the user right-clicks on each layer in the LayersPane widget (splitting, geometry cleaning, and resampling)
    • Batch operations on multiple layers available as buttons in the top ribbon area (merging and mosaicking)
  • Assign dialogue windows to set the parameters when running each tool
