Geospatial analysis is industry agnostic and a powerful tool for answering location questions. Combined with the power of SQL, developers and analysts worldwide rely on database integration to solve real-world spatial problems. This book introduces skills to help you detect and quantify patterns in datasets through data exploration, visualization, data engineering, and the application of analysis and spatial techniques.You will begin by exploring the fundamentals of geospatial analysis where you’ll learn about the importance of geospatial analysis and how location information enhances data exploration. Walter Tobler’s second law of geography states, “the phenomenon external to a geographic area of interest affects what goes on inside.” This quote will be the framework of the geospatial questions we will explore. You’ll then observe the framework of geospatial analysis using SQL while learning to create spatial databases and SQL queries and functions.By the end of this book, you will have an expanded toolbox of analytic skills such as PostGIS and QGIS to explore data questions and analysis of spatial information.
Geospatial Data Analytics on AWS. Discover how to manage and analyze geospatial data in the cloud
Scott Bateman, Janahan Gnanachandran, Jeff DeMuth
Managing geospatial data and building location-based applications in the cloud can be a daunting task. This comprehensive guide helps you overcome this challenge by presenting the concept of working with geospatial data in the cloud in an easy-to-understand way, along with teaching you how to design and build data lake architecture in AWS for geospatial data.You’ll begin by exploring the use of AWS databases like Redshift and Aurora PostgreSQL for storing and analyzing geospatial data. Next, you’ll leverage services such as DynamoDB and Athena, which offer powerful built-in geospatial functions for indexing and querying geospatial data. The book is filled with practical examples to illustrate the benefits of managing geospatial data in the cloud. As you advance, you’ll discover how to analyze and visualize data using Python and R, and utilize QuickSight to share derived insights. The concluding chapters explore the integration of commonly used platforms like Open Data on AWS, OpenStreetMap, and ArcGIS with AWS to enable you to optimize efficiency and provide a supportive community for continuous learning.By the end of this book, you’ll have the necessary tools and expertise to build and manage your own geospatial data lake on AWS, along with the knowledge needed to tackle geospatial data management challenges and make the most of AWS services.

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.

From Python programming good practices to the advanced use of analysis packages, this book teaches you how to write applications that will perform complex geoprocessing tasks that can be replicated and reused.Much more than simple scripts, you will write functions to import data, create Python classes that represent your features, and learn how to combine and filter them. With pluggable mechanisms, you will learn how to visualize data and the results of analysis in beautiful maps that can be batch-generated and embedded into documents or web pages. Finally, you will learn how to consume and process an enormous amount of data very efficiently by using advanced tools and modern computers’ parallel processing capabilities.
If you want to learn network analysis and visualization along with graph concepts from scratch, then this book is for you. This is ideal for those of you with little or no understanding of Gephi and this domain, but will also be beneficial for those interested in expanding their knowledge and experience.

Tym razem manna naprawdę spadła z nieba i... pomieszała wszystkim szyki. Zapowiada się kolejny nudny dzień na mławskiej plaży, przy pobliskim jeziorze... Co można zrobić, by jak najlepiej wykorzystać czas studenckich wakacji? Czy jest jeszcze szansa na to, by wreszcie zdarzyło się coś ciekawego? Dżako i Wór to znudzeni studenci na wakacjach pod miastem. Bez kłopotów i jakichkolwiek perspektyw aż do chwili, gdy pod ich stopy spada z nieba... sto kilogramów białego proszku. Na kilka dni ich nudne życie zmienia się w sensacyjną przygodę. Wpadając w kolejne opresje, poznają przestępczy świat i na chwilę zostają jego częścią. Wiesz, co to może być? Skinął głową na kupę białego proszku. Obaj wiedzieli już, co to może być, ale żaden nie śmiał tego powiedzieć pierwszy. Nie co dzień zdarza się, żeby z nieba spadała góra narkotyków. Podeszli bliżej. Zaczęli dotykać proszku palcami, brać na język. To chyba kokaina stwierdził Dżako, którego raz w życiu ktoś poczęstował podobnym towarem." Gerappa" to przezabawna czarna komedia z absurdalnymi zwrotami akcji, ironią narratora i soczystym językiem kolorowych, choć niekiedy bezwzględnych, bohaterów: przemytników z Tybetu, zakonnic dilerek, schizofrenicznego policjanta i niejednego prawdziwego mafiozo.
