Learning Geospatial Analysis with Python - Third Edition

By: Joel Lawhead

Overview of this book

Geospatial analysis is used in almost every domain you can think of, including defense, farming, and even medicine. With this systematic guide, you'll get started with geographic information system (GIS) and remote sensing analysis using the latest features in Python. This book will take you through GIS techniques, geodatabases, geospatial raster data, and much more using the latest built-in tools and libraries in Python 3.7. You'll learn everything you need to know about using software packages or APIs and generic algorithms that can be used for different situations. Furthermore, you'll learn how to apply simple Python GIS geospatial processes to a variety of problems, and work with remote sensing data. By the end of the book, you'll be able to build a generic corporate system, which can be implemented in any organization to manage customer support requests and field support personnel.

Python and Remote Sensing

In this chapter, we will discuss remote sensing. Remote sensing is about gathering a collection of information about the Earth without making physical contact with it. Typically, this means having to use satellite or aerial imagery, Light Detection and Ranging (LIDAR), which measures laser pulses from an aircraft to the Earth, or synthetic aperture radar. Remote sensing can also refer to processing data that's been collected, which is how we'll use the term in this chapter. Remote sensing grows in a more exciting way every day as more satellites are launched and the distribution of data becomes easier. The high availability of satellite and aerial images, as well as interesting new types of sensors launching each year, is changing the role that remote sensing plays in understanding our world.

In remote sensing, we step through each pixel in...
