Mastering Geospatial Analysis with Python

By: Silas Toms, Paul Crickard, Eric van Rees

Overview of this book

Python comes with a host of open source libraries and tools that help you work on professional geoprocessing tasks without investing in expensive tools. This book will introduce Python developers, both new and experienced, to a variety of new code libraries that have been developed to perform geospatial analysis, statistical analysis, and data management. This book will use examples and code snippets that will help explain how Python 3 differs from Python 2, and how these new code libraries can be used to solve age-old problems in geospatial analysis. You will begin by understanding what geoprocessing is and explore the tools and libraries that Python 3 offers. You will then learn to use Python code libraries to read and write geospatial data. You will then learn to perform geospatial queries within databases and learn PyQGIS to automate analysis within the QGIS mapping suite. Moving forward, you will explore the newly released ArcGIS API for Python and ArcGIS Online to perform geospatial analysis and create ArcGIS Online web maps. Further, you will deep dive into Python Geospatial web frameworks and learn to create a geospatial REST API.

Installing PostgreSQL and PostGIS on Windows

You can install PostGIS by installing PostgreSQL and then install PostGIS afterwards, or you can install PostgreSQL and then use Stack Builder, which comes with PostgreSQL, afterwards to add PostGIS. Using Stack Builder allows you to download the desired PostgreSQL version and with a single-click also get the correct PostGIS version.


When I installed PostgreSQL 10, Stack Builder did not include PostGIS. By the time of publication, this should have been added. Screenshots may show a different PostGIS version because I used an old copy of PostgreSQL to show how Stack Builder would work. You can download PostgreSQL from

As we proceed, I will walk you through installing PostgreSQL and then using Stack Builder to add PostGIS and a database. After downloading the executable, run it by double-clicking it. You will see the wizard as follows:

You can choose where to install PostgreSQL, but it is probably best to leave...
