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.

Signing up for a CARTO account

To be able to use CARTOframes, and to interact with data stored in the cloud-based PostGIS database service that CARTO offers, it is necessary to sign up for a CARTO account. While free accounts are available, with limited storage capacity and access to existing data resources, it is necessary to have a paid account to use CARTOframes, as these accounts are provided API keys. The API key will be used by CARTOframes to identify the account, with each data request sent to the user's cloud geodatabase.

A free trial of CARTO

By signing up, the account is initially a paid account with access to all CARTO features. The paid account offers a free 30-day trial that can be used to for evaluation purposes. Go to the site and create an account:

Once the account has been created, the 30-day trial period begins. This will allow you to add data to the cloud database, or to access publicly available data from the CARTO library. It also allows you to...
