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.

GeoDataFrames and geometries

In this section, we will learn the basics of loading and processing location data using the GeoPandas library. GeoPandas is built on top of the pandas and NumPy libraries. Like pandas, GeoPandas' data structure contains GeoDataFrames and GeoSeries. GeoPandas provides not only the capability to read and manipulate geographic data easily, but it can also perform many essential geospatial operations, including geometric and spatial operations, topological analysis, and geographic projections. You can also visualize and plot maps with GeoPandas (providing a high-level interface to the matplotlib library) by using the plot() method on a GeoDataFrame or GeoSeries. An important technique in location data analysis is the ability to convert simple CSVs or pandas DataFrames to GeoDataFrames, and that can be easily done in GeoPandas.
