Book Description

PostGIS is open source extension onf PostgreSQL object-relational database system that allows GIS objects to be stored and allows querying for information and location services. The aim of this book is to help you master the functionalities offered by PostGIS- from data creation, analysis and output, to ETL and live edits.

The book begins with an overview of the key concepts related to spatial database systems and how it applies to Spatial RMDS. You will learn to load different formats into your Postgres instance, investigate the spatial nature of your raster data, and finally export it using built-in functionalities or 3th party tools for backup or representational purposes.

Through the course of this book, you will be presented with many examples on how to interact with the database using JavaScript and Node.js. Sample web-based applications interacting with backend PostGIS will also be presented throughout the book, so you can get comfortable with the modern ways of consuming and modifying your spatial data.

What you will learn

• Refresh your knowledge of the PostGIS concepts and spatial databases
• Solve spatial problems with the use of SQL in real-world scenarios
• Practical walkthroughs of application development examples using Postgis, GeoServer and OpenLayers.
• Extract, transform and load your spatial data
• Expose data directly or through web services.
