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.

Building a graph based on a road network

In the previous sections, we learned about the fundamentals of the graph and many of the operations that we can perform on a graph using sample data that we defined. In this section, we will discuss how to import real-world data such as a road network and translate it into a graph and perform analyses on that. For this purpose, we will be importing sample Open Street Maps (OSM) road data that we have provided with this chapter.

Open Street Maps data

OSM provides a rich set of open source and crowdsourced geographic data of many parts of the world. In particular, we are interested in the road data they provide. For the US, they are baselined on census TIGER road shapefiles and benefit...
