Overview of this book

If you are an experienced Python developer and wish to get up-to-speed with geospatial programming, then this book is for you. While familiarity with installing third-party Python libraries would be an advantage, no prior knowledge of geospatial programming is required.

Accessing PostGIS from Python

So far, we have installed some tools and libraries onto your computer. Now it's time to use those tools and libraries to do something interesting. In the remainder of this chapter, we are going to import the World Borders Dataset into a PostGIS database, which we will call world_borders, and then use Python to perform various queries against that data. We will also see how we can manipulate that dataset using PostGIS and Python.

To start with, create a new directory named world_borders and place it somewhere convenient. You will use this directory to store the various files you create.
