Overview of this book

Geospatial analysis is used in almost every field you can think of from medicine, to defense, to farming. It is an approach to use statistical analysis and other informational engineering to data which has a geographical or geospatial aspect. And this typically involves applications capable of geospatial display and processing to get a compiled and useful data. "Learning Geospatial Analysis with Python" uses the expressive and powerful Python programming language to guide you through geographic information systems, remote sensing, topography, and more. It explains how to use a framework in order to approach Geospatial analysis effectively, but on your own terms. "Learning Geospatial Analysis with Python" starts with a background of the field, a survey of the techniques and technology used, and then splits the field into its component speciality areas: GIS, remote sensing, elevation data, advanced modelling, and real-time data. This book will teach you everything there is to know, from using a particular software package or API to using generic algorithms that can be applied to Geospatial analysis. 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. "Learning Geospatial Analysis with Python" will round out your technical library with handy recipes and a good understanding of a field that supplements many a modern day human endeavors.

Chapter 8. Advanced Geospatial Python Modelling

In this chapter, we'll build on the data processing concepts we've learned up to this point to create some full-scale information products. We will introduce some important geospatial algorithms commonly used in agriculture, emergency management, logistics, and other industries.

The products we will create are:

  • A crop health map

  • A flood inundation model

  • A terrain routing map

While these products are task specific, the algorithms used to create them are widely applied in geospatial analysis. The examples in this chapter are longer and more involved than in the previous chapters. For that reason, there are far more code comments to make the programs easier to follow. We will also use more functions in these examples. In previous chapters, functions were mostly avoided for clarity. But these examples are sufficiently complex, such that certain functions make the code easier to read.
