Learning Geospatial Analysis with Python

By: Joel Lawhead

Overview of this book

Geospatial Analysis is used in almost every field you can think of from medicine, to defense, to farming. This book will guide you gently into this exciting and complex field. It walks you through the building blocks of geospatial analysis and how to apply them to influence decision making using the latest Python software. Learning Geospatial Analysis with Python, 2nd Edition uses the expressive and powerful Python 3 programming language to guide you through geographic information systems, remote sensing, topography, and more, while providing a framework for you to approach geospatial analysis effectively, but on your own terms. We start by giving you a little background on the field, and a survey of the techniques and technology used. We then split the field into its component specialty areas: GIS, remote sensing, elevation data, advanced modeling, and real-time data. This book will teach you everything you need to know about, Geospatial Analysis from using a particular software package or API to using generic algorithms that can be applied. This book focuses on pure Python whenever possible to minimize compiling platform-dependent binaries, so that you don’t become bogged down in just getting ready to do analysis. This book will round out your technical library through handy recipes that will give you a good understanding of a field that supplements many a modern day human endeavors.

Tracking vehicles

For our first real-time data source, we'll use the excellent NextBus API. is a commercial service that tracks public transportation for municipalities, including buses, trolleys, and trains. People riding these transit lines can then track the arrival time of the NextBus. What's even better is that with the customer's permission, NextBus publishes tracking data through a Representational State Transfer or REST API. Using URL API calls, developers can request information about a vehicle and receive an XML document about its location. This API is a straightforward way to begin using real-time data.

If you go to (!/mu-rht/1/portlouis/margstan_o), there is a web interface to the data as well, as shown in the following screenshot, of the city of Los Angeles, California's metro system:

The system lets you select several parameters to learn the current location and time prediction for the next stop. On the right-hand side of the screen...
