Geospatial Data Science Quick Start Guide

Overview of this book

Data scientists, who have access to vast data streams, are a bit myopic when it comes to intrinsic and extrinsic location-based data and are missing out on the intelligence it can provide to their models. This book demonstrates effective techniques for using the power of data science and geospatial intelligence to build effective, intelligent data models that make use of location-based data to give useful predictions and analyses. This book begins with a quick overview of the fundamentals of location-based data and how techniques such as Exploratory Data Analysis can be applied to it. We then delve into spatial operations such as computing distances, areas, extents, centroids, buffer polygons, intersecting geometries, geocoding, and more, which adds additional context to location data. Moving ahead, you will learn how to quickly build and deploy a geo-fencing system using Python. Lastly, you will learn how to leverage geospatial analysis techniques in popular recommendation systems such as collaborative filtering and location-based recommendations, and more. By the end of the book, you will be a rockstar when it comes to performing geospatial analysis with ease.

Shortest path analysis on a simple graph

Suppose you want to connect to Barack Obama through LinkedIn; how many degrees of connection do you have to go through to reach Obama? A first-degree connection is someone who is connected to you on LinkedIn. A second-degree connection is someone who is connected to your first-degree connection and so on. Assuming that each of your connections and their connections respectively are interested and ready to help you network with the Obama, research says that it only takes an average of 5 degrees of connection for you to connect with Obama, or anyone in the world, for that matter. In other words, the shortest path between any of us and Obama is less than or equal to five. That sounds strange, right? This is known as the small-world phenomenon. And, fortunately, the shortest path between This author and Obama is only three.

This means that...
