Learning Geospatial Analysis with Python - Third Edition

By: Joel Lawhead

Overview of this book

Geospatial analysis is used in almost every domain you can think of, including defense, farming, and even medicine. With this systematic guide, you'll get started with geographic information system (GIS) and remote sensing analysis using the latest features in Python. This book will take you through GIS techniques, geodatabases, geospatial raster data, and much more using the latest built-in tools and libraries in Python 3.7. You'll learn everything you need to know about using software packages or APIs and generic algorithms that can be used for different situations. Furthermore, you'll learn how to apply simple Python GIS geospatial processes to a variety of problems, and work with remote sensing data. By the end of the book, you'll be able to build a generic corporate system, which can be implemented in any organization to manage customer support requests and field support personnel.

Geospatial PDF

The Portable Document Format, or PDF, is a file format for storing and presenting digitally-formatted text and images in a cross-platform and application-independent way. PDF is a widely used document format that has also been extended to store geospatial information.

The PDF specification, starting with version 1.7, includes extensions for geospatial PDFs that map portions of the document to a physical space, also known as georeferencing. You can create points, lines, or polygons as geospatial geometries, which can also have attributes.

There are two methods for encoding geospatial information within a PDF. A company named TerraGo created a specification that has been adopted by the Open Geospatial Consortium as a best practice which is not a standard. That format is known as GeoPDF. The extensions that were proposed by Adobe Systems, which created the PDF specification...
