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 operations

In this section, we will use the GeoDataFrame point that we just created and the polygons of the NYC census tracts to demonstrate different spatial operations. Before we can do any meaningful location data analysis, we need to check the geographic CRS of our data. As we have already mentioned, we have WGS84, and the coordinates are defined as decimal degrees.

Projections

It is a common process to reproject data from one format, such as WGS84, to other formats. There are many different projections; some distort shapes, others distort size, while other projections maintain an equal area size. Doing so is very useful for visualizing how different projections transform data, as is made clear at https://map-projections...
