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.

Spatial autocorrelation

Spatial autocorrelation is considered an Exploratory Spatial Data Analysis (ESDA) method where the concern is to visualize different patterns and clusters through geovisualization and formal statistical tests. Here, the intent is to highlight and explore the similarity of any given value in a dataset to similarity in terms of locations. Therefore, the concept of spatial autocorrelation relates to the combination of similarity between attributions and location.

In contrast to traditional statistical correlations, it does not target the relation of two variables and the change of one value in relation to the other. But spatial autocorrelation focuses on the value of the interested variable in relation to its location and surrounding locations. In other words, spatial autocorrelation allows us to study and understand the spatial distribution and structure...
